B Type Veins in Porphyry Copper Systems

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!

[kevintewey]

Tried to learn about this on my own for about 10 years and one day I watch a video and it all makes sense

[KimPhilipDalanon]

I admire your simple but informative lesson.

[martinovando]

Thanks for the video sir! and also Thank you very much for sharing your knowledge! greetings from Chile!

This is some good content about B Type veins and their role in magmatic-hydrothermal transition mineralization environments. Keep up the good work!

My favourite YouTuber!! Greetings from an Ecuadorian living in Australia 😁

[krr]

Wonderful, thank you for being such a great teacher!

[GreenMonkeyToaster]

I'm a biotech master's student, I've no idea how I ended up here but it sure rocks!

[kirklaird]

Nice presentation. Clear, concise. That's the way to do it!

[ToastytheG]

Duuuude you have no idea how helpful this is. Gracias.

[infinitygeospatial]

Thank you. With your videos, I am beginning to be a confident young geologist

[KF-bjce]

I think that this guy is in the rock library and has no difficulty understanding the content. Great stuff.

[SenorTucano]

I just love the fact that you got all dressed up to prospect in a car park. A true professional 👏

[johnlomax]

What an amazingly skilled and knowledgeable geologist you are. I'm not, but I have an amateur interest. I'm subscribed.

[ahmedaziz]

Thanks for sharing such a good information.

[manininikolas]

You have a really efficient look for prospects and good vue for minerals papa

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 ...!

Gracias por compartir. Saludos desde Venezuela

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

[MerchantMarineGuy]

Say I found an area with extensive b-type veins. Where should I be looking for the ore body?
