B Type Veins in Porphyry Copper Systems
Вставка
- Опубліковано 8 лип 2024
- B Type veins are a unique indicator of the magmatic hydrothermal transition environment where porphyry type copper, gold and molybdenum deposit form. Learning to identify them is a really useful tool in the kit for mineral exploration geologists.
They were first identified by Gustafson and Hunt in the El Salvador porphyry copper deposit in Chile:
Gustafson, L.B., and Hunt, J.P., 1975, The porphyry copper deposit at El
Salvador, Chile: Economic Geology, v. 73, p. 600-607.

Just got back home from my physical geology class and had a lecture about geologic resources so now I see this in my recommended... Great timing!
The UA-cam algorithm is scary smart!
Tried to learn about this on my own for about 10 years and one day I watch a video and it all makes sense
Thanks very much Kevin. If I transferred understanding, then my work is done!
This is some good content about B Type veins and their role in magmatic-hydrothermal transition mineralization environments. Keep up the good work!
Thanks. Hope it helps you find the next porphyry copper deposit!
I'm a biotech master's student, I've no idea how I ended up here but it sure rocks!
Haha, the UA-cam algorithm works in mysterious ways!
Thanks for the video sir! and also Thank you very much for sharing your knowledge! greetings from Chile!
Thanks. Lots of B veins in Chile!
Thank you. With your videos, I am beginning to be a confident young geologist
Great. There is a lot to learn, but it's fun!
Wonderful, thank you for being such a great teacher!
Thanks for supporting my videos with comments!
Nice presentation. Clear, concise. That's the way to do it!
Thanks Kirk. I hate it when people waste my time. I am determined not to do that to others!
Duuuude you have no idea how helpful this is. Gracias.
Thanks very much. If it is helpful, I have succeeded!
I think that this guy is in the rock library and has no difficulty understanding the content. Great stuff.
;)
I just love the fact that you got all dressed up to prospect in a car park. A true professional 👏
Haha, Korean Exploration always starts in a carpark, but it goes bush very quickly up the hill.

Thanks for sharing such a good information.
Thanks. B-Veins are very useful things :)
A real explorer! Great Job!
Thanks Hamdollah. Discoveries like this one make exploration a very rewarding job.
Thank you for such a good content.
Thanks Anuson. Hope it helps you to find the next porphyry copper deposit.
Another great video...people passing by may look at you and say... OMG he is talking to the wall! I find cladding on walls and tiles on floors of airports and shopping malls to be excellent polished outcrops on which you can spend time ...!
Actually there is an interesting tour of building stone in Adelaide. I made a start on videos for that, but it's a long term project!
@@GeologyUpSkill It will be very interesting to watch ... please try and capture the reaction of the public around you when you are talking to the wall ! Like your videos, please keep on posting!
Gracias por compartir. Saludos desde Venezuela
Thanks for commenting. Greetings from Australia!
What an amazingly skilled and knowledgeable geologist you are. I'm not, but I have an amateur interest. I'm subscribed.
Thanks John. Really, I'm just an ordinary geologist who spent too many years in the field and learned how to use a camera...
@@GeologyUpSkill ah. I sense humility. Nothing wrong with that.
You have a really efficient look for prospects and good vue for minerals papa
Thanks Nikolas. If you want to be a good exploration geologist, it is good to think like a prospector and use what you learned at university as tools of the trade.
@@GeologyUpSkill I am just an amateur I work more to improve my generale culture geologie vulcanologie astronomie paleontologist etc....we need specialist like you who go deep inside the history of minerals bravo my way is to have a 360 degree globale view I am a french sailor 37 years living on the sea
Thanks for sharing
Thanks Christian. Hope you find a few B veins too!
Thanks a lot, very interesting
Thanks Kolo. Glad you enjoyed it.
Awesome vid 👌
Thanks!
very cool!
Thanks!
Please make a video on D-type veins
D type veins are a much more difficult issue because the textures and mineralogy are similar in a wide variety of deposit styles. If you already know you are in a porphyry system, life is a bit easier, but still plenty of room for argument!
Are b veins likely to be present in an epithermal lithocap? Tomorrow is trying to high grade sample a hill of residual quartz, replacement and breccia... barren lithocap with patchy Fe and argilic zones
It can happen when a high sulphidation epithermal system above a porphyry collapses downward onto the top of a b vein zone.
@@GeologyUpSkill thanks ... seems to be low sulfidation and the top 20m is now spread on pine forest roads... but we might get lucky and find a gold mine in a quartz quarry. 👍
Could you please explain about Hydrothermal and epithermal system?
Epithermal is a low temperature type of hydrothermal system.
Wow I love these videos. You just earned a sub my friend 👍
Thanks very much. The UA-cam algorithm seemed to think geology wasn't much of interest to anyone, but this week, it seems to have decided that EVERYONE needs to know about B-Veins!
@@GeologyUpSkill I'm glad I found your channel. Gonna be binge watching as much as i can today. Keep up the good work and be safe out there. Thanks for the knowledge!
Say I found an area with extensive b-type veins. Where should I be looking for the ore body?
Right under your feet!
Nice teacher
Thanks Ahmed.
Muito bom bonito de mais 💯👏👏👍🤝
They are a thing of beauty!
Hey Nick, great explanation about B veins! Do a colab with Mr Peter Pollard!
It's in the editing room now!
thanks again Nick very interesting information just would like to no if you have information for prospecting for gold at all
You might find this one interesting. It's all about how to identify old alluvial workings. They are a great prospecting guide. ua-cam.com/video/w-u_haWkVlk/v-deo.html
Thanks Nick great video
سلام رگه های طلا در دل طبیعت پنهان را چگونه تشخیص بدیم
هر چیزی با گوسان بعد از سولفید شروع خوبی است.
I found a nice band of quartz with a thin black stripe running parallel to it in a finely grained gray metamorphosed hornfel earlier last month and wondered what in the world it could be. This has got to be it! Thank you!
That sounds exciting. If the rocks are hornfelsed, the intrusive can't be far away!
Another Hot Tip" Video!
Those veins are just so useful!
OK I figured out how to translate Auzzy to English. "Vine" is actually vein. And "nynain" is the number 19.
Haha When you upload to UA-cam there are several varieties of Engrish you can assign to the voice but Auzzy isn't one of them!
I presume you are in the Gawler Peninsula?
This one is in South Korea.
Is there a Sodomitic zone, too? I.e. with an enhanced sodium content?
In this case yes. Actually many porphyry style hydrothermal systems develop a core of sodic rather than potassic alteration (like this one) but they all get lumped into potassic because it is nearly impossible to distinguish alteration k-feldspar from alteration albite reliably in the field.
Hay bud if you get satellite map of Australia and then turn map upside down then look far right near coastal township of Karratha western Australia and then look closely and you'll see two huge eyes on head with a bird beak type snout with wings spanning across continent and tail feathers ending up near Adelaide South Australia. If you zoom down near Queensland northern territory border you'll see feather striations on the landscape. Mayby Uluru Ayers Rock could have been it's heart. Amazing incredible a winged serpent dragon Phoenix creature spanning two thirds of the continent. This only could have been discussing due to modern satellite technology. The story of our beginnings literally written declared in the landscape. Give it a crack and check out on g maps.👍 FN amazing!
Google earth is an amazing free resource no matter how you look at it!
@@GeologyUpSkill hay also check out satellite map of morocco and you'll see dragon image on map over 1000 miles long devouring fish similar size.if you travel down neck of dragon and zoom in you'll see scales on the landscape and the cut mark supposedly done by Zeus. Then go to Libya and you'll see huge hand with egg in it with a serpent surrounding egg then go south east of this and you'll see graphic image of woman against wall giving birth to something. Check them all out amazing! The story of the beginnings of this planet are literally written declared in the landscape. Only modern day satellite technology could reveal this. JESUS is Lord!
@@GeologyUpSkill if you go smack in the middle of Algeria on satellite map you'll see like a dragon horse type feature in the landscape. Check it out! Only a higher power could have made these images possible and deffently not paragloia! Ie seeing faces on clouds. Mother nature supposedly made these hmmmmmm I don't think so. A divine creator. Giants and flying beasts once walked the earth and their bodies have become part of the landscape through fossilization processes and the great flood of Noah!
@@GeologyUpSkill there's a great geological site called " mud fossil University" a guy Roger has this channel and gets heaps of stick from his fellow geologist biologists community. The evidence speaks for itself. Check out elephant rock in Iceland and the "Moana" lady giant in Maya bay Thailand. Awesome fossil giants. Check these out as well. Can't play games denying " FACT" enjoy! Research and homework.
@@GeologyUpSkill do you believe in yahweh God or are you a Darwin worshipper?
B veins are common in porphyry environments but not unique to mineralized ones. The exploration world needs to spend some time looking at what the geological norm is !
Yes. B veins only tell you that there is an intrusive issuing fluid. If that fluid is just bath water (the most common situation) you get nothing but quartz and a bunch of altered rock. Mineralization is a whole nuther story!
@@GeologyUpSkill This is a great channel. I will send to my students.
@@MrCinnabar That's great. I aim to make videos that will prepare students for field work.
The observations are great, but so called "B veins" are a made up term that essentially describes a relative timing or paragenesis/mineralogy, so something to be AVOIDED! A good description and measurement of the vein orientation, mineralogy, relative timing and mode of opening (extensional, extensional-shear, shear, unknown) is always preferable, rather than use outdated (1975) terminology. But again, some great observation and description skills here! :)
Thanks Agatha. I did note the origins of the name in the video and, like most pigeonholes in geology, it has become enlarged and distorted over time, but for me, it's just a convenient name for the collection of characteristics that I described in the video. I have found that collection to be a very useful exploration guide when I'm looking for porphyry type systems. There are similar arguments to be made about the "porphyry" system label, but again, it's just a convenient name that works.
Any chance its petrified biology
No. They are most commonly in igneous and volcanic rocks. Much too hot for plants!
are b veins related to metamorphism?
No. They represent hydrothermal fluid coming out of a crystallising magma.
