- CWU's Nick Zentner from his home in Ellensburg, Washington on Tuesday, May 12, 2020 during the global coronavirus pandemic. Common rock-forming minerals, identification, cleavage planes, hardness test, etc.
I know I’m late to the party, I accidentally came across your channel, all I can say is that you are a gifted individual, this world needs more teachers like you sir, thank you for sharing your knowledge
Man, this is great. I wish I'd found this channel sooner. Started watching Nick on the Rocks early in 2019 and love it, but I think this lesson on minerals is the best video yet by Nick. Thanks again Nick!
Another great learning experience.
Thanks from Australia 👍😎
Holy cow! You were so spontanaetous you made me sneeze!!
I'd like to thank you for all the videos you post, past, presently and future ones. I find them very useful in understanding geological processes and I find your delivery very engaging. Scotsman
Dang it, Prof. Zentner! I've only been following your Big Floods channel! This is a whole treasure box of videos to watch while I am also drinking wine!!! Thank you!

I'm so glad to review these! I've learned so much since your first sessions, but there's still a lot to put together. Thank you, Nick.
Lovin' this one Nick. Learning and laughing at the same time. How can you beat that?
I loved this basic Geology 101 lecture. Thank you!
Watching this was so much fun! I've only been watching Nick videos for a couple of weeks. Wish I'd discovered them earlier, but I can see they'll keep me entertained for a long time to come. I don't mind saying I'm a 69 year old woman, been collecting rocks and minerals for 40 years just because they fascinate me, and I've never taken a geology class (but I read a lot). (I got most of the mineral samples correct.) I would love to have taken your classes; you really make this fun and interesting! Thank you.
by far the best quarantine content ever. I can't believe how much you are teaching us all, it is a huge service. Taking the whole program with notes!!
I have waited YEARS to see your collection, Nick! Thank you!
I'm really enjoying your videos, Nick. I'm learning so much. I want to thank you for not monetizing them since you clearly have enough subscribers and viewers to do so.
True. I would watch anyways but I sure do enjoy watching without the constant ads.
Memories. That 2nd book you showed, "rocks and minerals", was one my mother the geology hobbyist had -- and used a lot. We moved to Butte when I was 7, and she discovered the library at the Montana School of Mines (now Montana Tech) and was in 7th heaven. We moved back to Bozeman in 61 after my dad retired, and later we as a family joined the local rock club, with one of the lecturers being Dr. Montagne from MSU there.
Those two yellow stones look a lot like Apatites. Galena is one of the heaviest minerals, and it is the primary source of lead, and that is why it is so heavy. Thanks, Nick. Since I am a rockhound, I loved your presentation. And thanks for hauling over your rocks.
I would have loved to be in your class! Thank you so much for your wonderful lesson! Much love to you and yours from Windsor, ON Canada.
Watching from New Braunfels, Texas - Limestone galore
I always love your lectures Nick! I learn every time! A couple quick notes on it though, plagioclase and the orthoclase feldspars both come in a wide variety of colours (I'm Canadian, that's how we spell colour). I have peristerite that's so pink it's almost red, and peristerite is in the plagioclase series (albite with about %10ish anorthite). Opal isn't a true mineral because it doesn't always have the same or even any crystal structure. Calcite does not effervesce because of the calcium. The reaction is occurring between the acid and the carbonate component of the mineral. All carbonates effervesce, regardless of the metal ion.
Wow, learned a lot today. Completely new field of knowledge for me. I actually enjoy learning about the nuts and bolts, but that’s the kind of musician I am, preferring scales and technical exercises to learning pieces.
Looks like you need a Grip😀
By the way, Nick, you are a blessed man. So many people think about you in their days and then send gifts to help you and yours understand how happy you make us with all you teach.
Thank you.
Okay, you stumped me on the calcite. I did not recognize that. I'm used to more clear forms of calcite. This was a great class, Professor Nick :)
Janet from Ridgefield, Wa - thank you so much for this. I learned a bunch and relearned a little.
Hey Nick! Love the videos! I was curious to know if I or anyone could get a copy of that mineral identification guide from that lab manual. Seems very useful! Keep up the work!
yes indeed
As someone suggested, take a screen shot.
Ours is the Crater Rock Museum in Central Point, Oregon. If anyone is in the neighborhood you should stop by.
I find peristerite in the ballast on the train tracks near my house. That *blue* me away, ahahahaha....
After how many lessons can we virtually graduate? From The Netherlands a nice day.
DANG ! THAT"S EXACTLY WHAT I'M THINKING ! ¿¿¿🤪¿¿¿
-an 'Eratic' day (but a great one !) 🖖
You make me want to attend your classes. Thank you
Rutile is another mineral that regularly forms twinned crystals
Thank you, Nick. Loved the lesson and learned loads. Cheers from Hereford in England.
Rutley's Minerology used to be the go to book. No fancy photos though! :)
I cant believe how much of a nerd I've become because of your videos. I'm expecting a giant wedgy any day now!
Thank you !
Love your teaching programs as a retired Firefighter HazmatTech I suggest you get ride of the swirly light in your lamp or anyplace else they are highly toxic and I don't want you to be lost to us before your time! :)
Come on, you have break the light and the amount of mercury in them is about the size of a period on a printed page. As you must realize, many people have been exposed to far more mercury than that back in the day when we played with mercury thermometers. And also, how about all the millions of fluorescent tubes that use mercury vapor? They've been around for a very long time and are still in most commercial buildings. So obviously, the term 'highly toxic' is overblown. Be careful with them and recycle them. LEDs are more efficient so as the twisty bulbs go bad, use LEDs to replace them. No biggy.
The fact that there is a small amount does not negate the fact that it is still highly Toxic. Its bad enough that the E.P.A. has a notice dedicated to the hazards of the clean up.
Its not any worse then any of the other nonsense going on right now in this country but hey you got your two cents in. I hope it fixed your need to be correct, right, righteous
Accurate and upright.
@@davidstarr3566 So you are purposely putting out information that isn't very accurate and you don't mind? And when I point out that it isn't a big danger like you made it out to be, you get upset because you don't think anyone should ever correct you and then you have the audacity to tell me I have a need to be correct? You need to cut back on the alcohol or whatever.
Love the show
Considering we are sharing cleavage we should have an intimate relationship LOL 😂 I have really enjoyed this lecture and am going to watch the whole series 😊 Thanks for your time and hard work.
SUBTITLE: Always get permission first if you want to use something you found in the basement AND YOU DIDN'T PUT IT THERE.
HOW DOES OR DOES MINERAL HARDNESS AFFECT FOLDING AND FAULTING?
That was awesome!
I suppose that I am a Grandpa that liked Deep Purple as I'm so old !
OMG! Them cookies look sure damn good!! (hahaha)! The Harvard Mineral Museum in Boston is pretty darn good! There is a lot of mineral information on the Internet, including the geologic, scientific, and metaphysical aspects of minerals.
Colour? Why it occurs is easy. It's all to do with electrons in chemical bonds absorbing only some frequencies of light: the ones they don't absorb are the ones that you see as the colour. If everything visible gets absorbed it's black. If nothing visible gets absorbed it's white.
So what determines which frequencies exactly get absorbed? This is where it gets complicated.
Most crudely it depends on which chemical elements make up the mineral in question. Vanadium minerals absorb differently to iron minerals and copper minerals are different again etc, etc. Oxides are different to nitrates or chlorides. Each chemical element has a fundamental configuration of its electrons, determined by quantum mechanics. The exact interactions of the different electron configurations vary from mineral to mineral.
However it's not just the chemical elements themselves which matter. The ratio between the elements in the mineral matters. For example two main copper oxides exist: CuO and Cu2O. The former is red or yellow in colour and the latter is black. In other minerals copper is famous for its strong green colour.
Then there are other factors. Particle size determines whether CuO is red or yellow. Impurities can also be strongly determining of colour: fluorite in its pure form is colourless and the yellow, purple, green and blue crystals shown in the illustration all have different impurities in them.
Sometimes physical arrangement of atoms can also be very important. Diamond and graphite are both pure carbon. The only difference between them is the physical arrangement of the carbon atoms.
So yes what determines the exact colour of a particular mineral is very complicated.
34:50 Just realised Nick sounds like The Dude from the big lebowski
Jeff bridges.
love love that movie, you are right, he does sound like Jeff bridges,
One of my favorite movies. You’re right! I first discovered Nick’s podcast and thought the same thing.
If someone spiked his white russian with amphetamines...
cant w8 for sutarday. much to explain, much to learn. :)
Why are certain minerals in certain places? Why some minerals are mixed together like cuartz/metal ores??
"Should I?" F**k yeah!
Your lectures and information give me hope. It appears that not all content on youtube is meant for the morally and mentally bankrupt. Thank you.
I wonder what the black is in Biotite Mica (is it Horneblend?). I have learned in my mining years that lots of minerals have other minerals nearby. In a pegmatite, if you see Lepidolite, Tourmalines are not far behind. Galena (a source of lead) is definitely in the heavy category. What is the name of the last book that you showed with the Halite? I love you too!
Hi Nick do you have any recommendations for places/websites to obtain geology equipment like you use to break minerals and rocks apart?
What a beautiful street you live on. Unfortunately, the grey color in the grey houses and grey sky didn't work with a grey rock!
Glad we went back in BUT I hope you can show us those rocks again in the bright sunshine-field trip?
Do quartz crystals ever naturally have a pyramid at both ends, or are the ones in shops that do, ground to look 'whole'? I've only seen natural ones growing out from amorphous bases, so there is usually only 'one end', and without cleavage planes, single crystals can only be got by breaking them.
I know this is late out of the gate, but Nick, could you tell me if there is a mineral similar in appearance to pyrite that is a silver gray in color? The daughter of a friend gave me some samples and there is something like that in there. I'm wondering if the thing is naturally occurring or some kind of industrial waste she may have picked up. I'm not sure, but if I remember correctly she picked it up on a trip to the White Mountains of New Hampshire.
Nice shot on that halite!!!
1:28:50 The most perfect crystals actually grow out of (aqueous) solution. That's certainly true for Quartz crystals. At the temperatures and pressures that water can take on deep underground, it can dissolve enough SiO to allow Quartz to deposit out of it. (In fact, even Gold is concentrated and deposited that way.)
Could what you think is a mineral actually be a rock composed of different minerals of the same color?
Im not sure if it was you or not but I tried to get a quartz with inclusions identified at the rock show in kitsap county think i accidently said psrk instead of buckhorn forest of the national forest
Doesnt hornblend have something to do with radiation or nuclear science?
In *GENERAL,* "no cleavage" may actually be "Conchoidal fracture" (as in the sea shell, do an Internet search on "Conchoidal fracture"). Some rocks/minerals with conchoidal fracture are: _agate, flint, glass, obsidian, petrified wood, and quartz / quartzite._
*Spoiler(s)* : _Obsidian,_ an igneous/volcanic/natural glass, can produce extremely fine, brittle, and sharp edges. A fractured edge can be a mere molecule thick and much smoother and sharper than surgical steel _(see obsidian edge vs. steel scalpel edge under a microscope)._ Thus, if you are faced with surgery and wish to have little to no scarring afterwards....require the doctor to use, expensive, obsidian scalpel blades.
- *WARNING* -
Because obsidian edges can be so sharp, be careful in handling - treat it with great care and respect. Otherwise, you might wind up in an emergency room...
_See also, "flint knapping" or making stone arrowheads, projectile points._
A new kine of mineral on Tower hill in Monroe Wa.
The Wifie's Mason Jars... LOL Know your boundaries! Learning a lot from you!
Thank Eugene? or Thank you, Gene, or Thank you, Jean? And was that cookie Conglomerate, or Breccia, or both (raisins AND chopped nuts) ?
talk/present and speak to the LENS of the camera not the viewfinder--otherwise well done!!
Great information. Intriguing and excellent geology lessons. Thank you.
Love from India 😆😆
Are the rare mineral samples rare because they are hard to find or is it because the Earth does not produce that much of it?
Both. Some require lots pf pressure or heat, at great depths; some form magma at shallow depths.
you lost me at healing powers or was that power rangers
You aren't kidding text book racket. The profs that require theirs or a friends book with hundreds to spend is ridiculous.
@A Sojourner Fore sure. Sports and recruiting are all standardized but the text book games ridiculous. Deans probably are getting a cut through printing companies its so dumbfounding. Probably an even bigger bust than the pay to have your kid enrolled in schools.

just a thought about dating, there is new information that the speed of light is NOT constant and many datings may not be as accurate as formerly thought.
I don't know why the speed of light would affect the dates. The fact that we get the light from the sun in about 8 minutes would imply that even if the speed has varied, the amount would be so small as to be meaningless inside our solar system.
@@jollyandwaylo explaining the science would take pages, in short carbon would still decay at a set rate but the mechanism would not account for the variations in light molecules measured. and it would definitely be obvious inside the solar system
@@elizabethjansen2684 Light molecules? I'm lost. I guess I'll wait for one of my science sites to bring it up.
What a load of pseudoscientific nonsense!
If you are saying that the speed of light in a vacuum isn't constant you are saying that Einstein's theory of general relativity is wrong. We know general relativity is incomplete and a considerable refinement is needed to merge it with quantum mechanics. That is NOT the same as claiming that the speed of light is not constant!
Does the speed of light in different mediums vary? Yes. That's why refraction occurs. However when people make claims like the above that isn't what they mean. What they mean is the speed of light in a vacuum. What they mean is that they are disputing general relativity. Any disputation of general relativity has to reproduce all of the correct predictions of the current theory and then make further accurate predictions that general relativity does not make. This is a hard task and is certainly beyond the ability of some random UA-cam commenter!
Also another thing that makes this pseudoscientific nonsense is that radioactive decay is NOT an electromagnetic phenomenon. Radioactive decay is governed by the weak nuclear force. The kind of physics needed to unify weak and electromagnetic forces into the electroweak force is so exotic as to be discounted in ordinary conditions on earth.
Don't try and make claims that are pseudoscientific claptrap in the comments of this channel. There are enough people who watch the videos with real, significant science backgrounds (like me) around to call things like that out. Doing so merely makes you look incredibly foolish.
I love talkin rocks
21:09 Krystle Carrington ?
diamond is also th efirst mineral in the universe
I don't know. Certainly Carbon is an early element produced by fusion in stars, but there are other carbon minerals (ie,: graphite) that don't nee the pressures needed to produce diamond.
@@judychurley6623 First minerals are nanocrystalline diamonds, which condensed from gases ejected when the first generation of stars (gen III stars) exploded.
Jesus Marie....
Try discussing meteorology with someone who gets weirded out by the word "moist."
Doesn't work either :P
