- Glad to have you studying with me! I have more content in the works and I hope you'll enjoy it. For those that are interested, the best textbook out there is this one: amzn.to/47VNed8. However, it's a little old now (two of the authors have passed away) and if you prefer a newer textbook, I would recommend this one: amzn.to/45UFDcR
For other introductory geology lectures: • Introduction to Geology
This video is my lecture on sedimentary rocks. It covers the textures and origins of sedimentary rocks, the minerals frequently encountered, and the depositional environments. I hope you enjoy it! This video is also closed captioned.
You have helped soooooo much in my Geology class. I’m 68 years old and I don’t remember being so excited for a class during all my studies as a younger person! Thank you!
You are so welcome!
I'm a retired commercial fisherman who loves geology. I love these lectures thanks for posting them.
So grateful to hear that!
Mars! I knew it. You are a great teacher. Don't normally do hour lectures, but you keep your cursor on the things you explain.
This has answered alot of my questions on the different types of rocks I've found on the shores of the great lakes. Even answered a question on fossil coal I thought was just a cool collection piece. I love learning about our earth thank you for being a cool teacher with passion of the same.
This was a fascinating video! Thank you for sharing your knowledge in such a clear, understandable way.
Truly, this series of lectures are a treasure for a layman like me.
Best lecture so far on UA-cam.
These lectures are such a gift! Thank you!
You are so welcome!
If you learned general chemistry, because NaCl salt is aqueous, which could be further marked as NaCl (aq), it is dissolved in water. When water is evaporated in that case, the solid salt is what is left
Excellent series of very useful videos - thank you!
Glad you like them!
Thank you for help us expedite research supports and translational sophistication with open honesty, taking us futher than lesser examples unwanted.
"Detribal set if rocks" ! Thank you so much!

Gracias por compartir, saludos desde Venezuela
As usual, great class! Please keep them coming.
More to come!
Great presentation thank you!
This lecture series is a treasure! I have watched the first 10 lectures and enjoyed all of them. Plan to watch all. You do not get enough exposure! This course should be in Coursera.Thanks a million!
Excellent video! Great teaching! I learn so much from listening to these videos. Please keep it up.
Thank you! Will do!
Excellent presentation as always- thank you !
Thank you!
This was a good watch.
I did ask a chunk of Kimberlite why it has angular and rounded minerals in it's matrix why it is not a conglomerate or breccia but looks like one. It said because water has nothing to do nor ability and time to react with me.
I watched all your episodes, and this is my favourite section. Thank you so much for putting this together it's so much fun to know how what to look for when doing a research about any of those subjects
Thank you for your appreciation!
You should introduce the theory of "inorganic origin of oil" which is very popular and important now. So much of methane in other planets in our solar system and they can be the source of the oil/gas in our earth.
thank you !!! GREAT LECTURES !!!!!
Chalk under a microscope looks....interesting, woah. Might gave a peek at it myself.
Also, this lesson was very exciting for me. Ty
So a question I've always wondered about might be only vaguely related to the deposition of sediments along the coastline, but it got me thinking about the footprint in a million years for future geologists (you know, after we've all left the earth and it becomes a nature preserve) looking at the Galveston Bay area and how it has been affected by the urbanization of the area. But I digress. I've been told that the dirty murkiness of the Galveston Bay water is due to run off from Houston and the churning up off silt by the huge ships entering the Houston Port. So, as far as the Facies go does it push the mud layer further up or will it adjust property dragging the finer sediment further out to sea?
The silt and clay (mud) particles that are suspended in the water will likely be discharged further out to sea rather than depositing in Galveston Bay due to the environmental perturbations. Great question!

We have recently moved to SW Missouri, where all of the rock is sedimentary. It lays in beautiful layers, some very thin while some of the mudstones appear to be quite thick. We also see examples of changes in the composition of the layers, from sandstone, gravels, limestone, dolomites, etc. My question is: How do we tell the time lines of these layers? Some are likely single events (such as the thin white line we see in a particular road cut), while others are repetitive uniform layers. So, what is the time factor? Can some of the thin layers be as short as annual? Are some millennial? Is there anyway for a casual observer to make an educated guess?
THIS IS BEAUTY OF NATURE
What geology book do you guys recommend?
Awesome video!!!!
Me, a senior in college: wow fascinating! I love all of these lectures about sedimentary rocks. I've learned so much about myself. In addition, I was born and raised in Moab, Utah, so these rocks are a part of my cultu-
The video: geology 10
Me: 😭😭😭😭😭😭😭😭😭😭
Ok thank very much i understand，and please keep up the excellent work i have learned alot about geology without spending a day at a university. Thanks again
thank you! Can you recommend a study book?
🙏 many thanks for all these videos, they help a lot.
Great lecture! thank you
You are welcome.
Excellent video
Thanks. real cool information.
So informative 👍👍👍
Hey im a prospective student of the university of Guyana and just want to know if the opal (fire opal) is really a mineral or a mineraloid since it dont have a crystalline form or structure?
It depends on the type of Opal, but almost all fire opals are opal-A where the "A" stands for amorphous. True opal-A is a mineraloid. However, many opals evolve over time and crystallize to Opal-CT, at which point water is expelled from the mineraloid and cristobalite and tridymite form as diagenetic replacements minerals.
awesome lecture
I have enjoyed the class...
Fantastic. Thank you.
Why doesn't sandstone form in the bottom of lakes ? Is it the lack of a good mineral matrix that deposits from water, as in seawater ?
Mainly because sand forms and deposits in higher energy environments like rivers and beaches. Lower energy environments, like a lake, don’t typically have the energy to move large-grained material, like sand.
makes sense, although i find interesting that lakes are still able to round pebbles, maybe they'd take a lot longer than the sea to make sandy areas@@EarthandSpaceSciencesX
@@mahneh7121 lakes can definitely round off cobbles and even create sand along the lake edge if there’s any wind-generated waves. The Great Lakes are an excellent example of that.
thank you for your videos and for replying, i'm grateful for this.@@EarthandSpaceSciencesX
Yes, well done !! 😍😊😎🎶😃✨
Wonderful
Great Lectures..thanks for posting them..quick question...i have been drilling in clays and have notice black nodules no more than a couple millimeters...What would these be?...Thanks
It depends on so many factors that I doubt I could answer that question reliably.
Give information for water bearing strata in alluvial zone in Sabarkantha district in Gujarat
good show
I love you. Seriously
What kind of microscope are you using during min 13:50 ??
It's a standard petrographic microscope under cross-polarized light.
Nice lecture
Thanks!
At 15:31 You are seeing a sloped surface which looks like a water eroded face, but it is muscle tissue of a creature, and what you see is a sarcomere, or pinch muscles which are found in the diaphram or other areas where squeezing or contraction is followed by regular expansion. The same structure is found in Petra (Edom) in Jordan in the treasury building, carved out a red sandstone, again muscle tissue. Roger at mudfossil university has documented two DNA tested humanoid giants of about 50 and two hundred feet height, and he explains the earth is mostly body parts, humanoid and dragon. The first image at the beginning is muscle tissue of a shoulder region, it is easy to see, even from that one image, this is not from erosion, and that is impossible given the fluting is visible and not along any watercourse. Yes this is being suppressed but many geologists have simply been sucked into the British idea the earth is really really old, and there is no God. THE flood is the source of the all granite, which is flesh, and so is mudstone and shale, which is tendonous and sandstone can often be tendons.
in inorganic limestone: did the calcium carbonate still in the first place originate from lifeforms but it has been entirely dissolved, transported, and re-presipitated into travertine, ooids, or some other formation. i.e. we could say lifeforms produced the material, but not the formation?
Turns out that life is not required to form oolitic limestones or travertines. Travertines formed in Italy, which are famous for building construction, originate through carbon dioxide reactions associated with volcanism. All that need to be present is sufficient carbon dioxide and the right environment. Also, many evaporite deposits contain considerable amounts of abiotic calcite. Hope this helps.
i experienced that sandstone can form in a few months with multiple lines and all
It can form quickly under certain conditions. Beachrocks are an example of this.
Thank you so much for the great series :)
55 million years old yea? How exactly did you come up with that calculation might I ask?
Very good my friend
Cant sed. R8cks be deposoited into the oc3an and then later be pressured to Stone? Like how did Oil happen. Sorry for spelling
Why does salt prevent things from growing
Good!
Thank you! Cheers!
Love your lectures! One thing, it seems that what you called a "fire opal" is actually a "precious black opal" I may be wrong but thought id put it out there
Would like to see you on Modern-Day Debate or some other channel to debate people like Kent Hovind. Would be nice to have people exposed to hard science rather than bickering and arguing. I think you could present such a nice presentation.
Hi Debating KH is a waste of time. He would value the publicity. "Never wrestle with a pig. You just get dirty and the pig enjoys it".
THANKS
You're welcome!
Nice

I need to add Chert / Flint to my collection
I knew the upper left picture was Mars. I can't believe it, someone likes coins. The arkose sandstone has an Indian Head penny (1859-1909) on it!
As a life long numismatist myself, I just had to use that photo in the presentation!
Thanks sir great lecture
Show!
👍👍👍
lookup Peter Mungo Jupp's instant fossilization and Andrew Hall's shock wave geology
Why?
Made so simple

Oil is better understood as igneous or abiotic. It does not come from decaying living matter.
😯🙏👍👍
Mudstone is cool because it is anoxic, i.e. formed before there was oxygen in the atmosphere.
formed by supersonic wind and plasma, magnetic fields separate the materials and lay them down instantly.

This is exciting and beautiful
I know of a missing link in the education of geologists. They tell us that our planet Earth has the most to fear from an asteroid impact or volcano eruptions. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Mayans and others. They tell us about a cycle of seven disasters that separate the eras from the world. Certainly, regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and small and larger meteorites. Forests that existed are flattened and because of the pressure from the layers on top the wood is changed into coal. These disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its chronology and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
The link is missing for a reason. It's pure BS.
@@alanthompson8515 Thank you for your reply. This is not a matter for geologists only. This recurring disaster is alive and kicking throughout the history of mankind and its religions.

Caption not available and I can’t understand your language because I am Indian while I was interested
cool beans. when you talked about agates and and chert you said flint sparks, not true. flint and steel sparks because the flint is harder than the steel and is shaving the steel . carbon steel that is. you dont need flint for that you need a rock that is harder than the steel.
Thank you for the interesting comment.

I'm already guessing MARS!
Yup.
Andrew Hall has a different story
Pictures of Mars... o..k..
Sedimentary rocks was formed after the Great Flood in Noah's time. I think the waters washed inland in tsunami fashion and then flowed back off the earth similar to the action of tide.
Beautiful sceneries though
The Flood is a myth .
Kaip koks sluoksniuotas tortas
The biblical flood is the best explanation for all geology on the Earth. Its how you interpret the facts we have many layers millions of fossils that's a fact but how they got here and what happened is all assumptions and ideas
B*ll*cks! You clearly have never even started a Geology 101 course. Finish one (you don't even need to pass) and then make comments based upon knowledge rather than dogma.
@@alanthompson8515 I study geology plenty and I know the flood happened, the evidence is everywhere but people choose to deny it.
@@phillipgray7371 Taking you at your word, your geological knowledge should make it easy for you to mention an example or two of this evidence that is "everywhere". It's your claim, so naturally, you go first.
Perhaps you could predict something that would be visible after such a deluge? Something NOT explainable by other natural processes?. Something that operated on a global, not just local, scale? And then point out places where evidence that this prediction is correct can be seen?
As for myself, I also "know" that the Genesis Flood did NOT happen as literally described in Genesis unless (i) the supernatural exists, (ii) a deity as described in the bible exists and (iii) that deity is a trickster who makes natural laws only to break them as and when the whim takes him/her.
If you remove the God Did It excuse from the scene, and make the natural assumption that (God's?) natural processes remain basically unchanged through time, then it is 100% certain that the Genesis Flood COULD NOT have happened.
BTW if you wish to challenge this assumption, please tell me a reason (other than the deceit already mentioned) why the deity WOULD change them or how they COULD change naturally.
@@alanthompson8515 I do take the biblical account as a witness to the flood when I do all my examination I look through the eyes of the testimony of the flood now I can't show you my evidences through this chat I have to have an email but there's some UA-cam videos out there you can go watch one is the hydroplate theory with Brian Nichols I don't escribe to all his theories but most of them work I have scientific studies of mountains forming and how and how Continental shelves formed and river valleys and observe them myself What we observe in nature could not have been slow tectonic processes. IT had to be rapid the way the layers are smash without breaking proving they were soft, polystrate fossils ,fossils in general,rocks suspended in Upper layers that came from the lower layers coal seams,oil and gas if you've been educated in the current system you'll be blind to these facts but I'd love to try to open your eyes if you're willing but don't waste my time if you don't have an open mind please.
@@phillipgray7371 Ah! So NO predictions that can be checked?
You somehow CAN'T show any evidence (BTW the word evidences is a verb not a plural noun).
You point me to UA-cam videos, which everyone knows are always totally reliable sources of scientific knowledge. NOT.
You mention PRATTs like hydroplate theory, polystrate fossils and hydrocarbon formation despite the existence of longstanding, elegant and very well understood explanations for all of them.
It is YOU that has the closed mind - there are none so blind as those who will not see. I know this because I was once as deliberately blind as you. Luckily for me, my loving and very devout parents encouraged me to always do my best at school. Thus I discovered the undeniable power of the scientific method. In time, 1 Corinthians 13:11 kicked in. I lost faith and started instead to trust.
Unlike you, I soon found that science was not a pick 'n' mix assortment. All its disciplines shared the same approach - methodological naturalism - so to diss one was to attack all. While parents and pastors loved to deny speciation (biology) and deep time (geology) they quite happily embraced the many and varied fruits of scientific endeavour, such as anything powered by electricity. This struck me as hypocritical. How does that sound to you as you type away on the internet?
This is a petrified slab of meat from a giant. You are looking at layers of the body---not geology.
Not buying all of this.
What if I told you that's tree rings? Your sandstone beds are the remains of Assyrian. A giant cedar.
