The Fascinating Process of Gold Formation in Quartz Veins 

Your presentation is obviously from years of reading combined with lots of practical experience. You mentioned important things that are often ignored by many "professionals". I wish we were neighbors because you have a wealth of experience that needs to be shared. I'm looking forward to watching all your other gold related videos. Thanks for posting.

Very good. Here is Southern California, you hunt the iron saturated quartz that looks like red rust on the faults. They call it reef gold, meaning it is always microscopic. The goldless quartz is the clear to white milky quartz, called bull quartz. Here is the US and Canadian shield, metal bearing ore deposits are commonly in volcanogenic massive sulfide (VMS) vents of Precambrian age. The sulfide zone forms the top caprock. Stockwork gold is lower down in the pipes and fissures of the vent. Looking top-down, you get the sulfates in the outer ring (aureole), the sulfides ringed inside that and the ore body proper in the center. The common sulfate indicator is barite, often for lead deposits, which mix with gold and silver.

Great video, a little deeper understanding than the other videos. Loved the explanation of intersecting faults and the formation of rich pockets. Much appreciated.

You have much common sense on the nature of where gold lives. Thank you for sharing! My experience in the USA suggests that gold deposits often wear an iron hat and come dressed in a white coat with color that may include red and, or, orange...Believe it or not gold is very common way down deep at the gold layer. What makes gold rare near surface is a lack of transport and porosity mechanisms.

A big thankyou for sharing this information my friend,, i really enjoyed this lesson,,it makes sense without the BS,, i did not know this as in depth as what i just watched,,,,once again a very big thankyou,,cheers

Amazing explanation, that just connected all the dots very quickly. Down and dirty! Thank you!

Thanks that was a great presentation.The key to successful prospecting is to take your time and think about the knowledge you have learned and apply in the field. Cheers Greg

Thanks for the simple visually aided explanation Bruce, much appreciated!

this quartz theory of gold Very helpful to me Appreciate your style Thank you

I always wondered how gold formed. This is so interesting. Very educational. I picked up two pieces of grey and black granite of with small bits of gold in my veggie patch. We live on low hills with, I heard dolomite domes inside. Down at the river I found some of this cement like crumbling rock with very small thin specs or flakes in shiny gold colour. Most of the specs I believe is calcite as it shines white. I have seen outcrops of snow white quarts fault lines running in places next to our streets continuing underneath and popping up on other side of roads, running into some yards. 🥰Thanx. Very interesting. Now I can stop wondering as my books on minerals did not share this expert knowledge.

Thank you for sharing so much knowledge with us. Its so nice to learn these things to be able to use in the field.

I really appreciate your enthusiasm. After watching this, the only thing stopping me from finding gold in western Australia is that I am not in Australia or remotely close. Still, great video.

Thank you very much Really interesting I did like geology at school .loving that I can learn this now .Thanks again

Great Video! I live on iron ore rich grounds and I’ve seen many different quarts veins and rocks. Very interesting, Thank you for your knowledge

Brilliant presentation thank you

Hi Greg, Your Videos are a breath of fresh air. I have done a course to find gold. Well at least get closer to the gold and have applied it and have succeeded by good fortune or good detecting don't know but yes, I have learned to look for this type of quartz crossed with mineralization and have agreed with you white quartz that covers 90% of the Earth surface and it definitely does not always have gold! When I try to explain that gold has come only 5 to 10 klms to the surface of the earth in the goldfields I get a blank stare. People say gold is where it is! What a statement. Gold is getting harder to find if you spend your time around mines and drill holes. Having knowledge of what you have explained here is phenomenal! Keep the videos rolling. Regards and cheers for the New Year.

I’m in Oregon just wishing I could walk Australia grounds for like a week! Y’all have the coolest gold hunts tbh!

Excellent, thank you! Very interesting how W.A. gold differs from the East. e.g. Victoria. W.A. gold is old gold connected to regional enrichment thru Achean rock. As you stated billions of years old. Typically you find low grade ore in this ancient parent rock. Yet Victoria was the opposite. Volcanism! The East Coast was a "hot" bed. Lot's of "hot" stuff leaking to the surface. Result "large" nuggets!!!!! ❤❤❤❤❤

Hello, God bless you. The explanation of tectonics and formation of gold with quartz was excellent. My question is about the formation of large nuggets similar to the Australian formation. Also, there is fine-grained gold as small as 70 microns in the mines of the Middle East, which is why there are coarse gold nuggets in Australia and Africa. But in the Middle East, gold is 30 to 100 microns? Thank you in advance for your answer.

Excellent description! Thank you very much!

Great presentation,thank you. I know in a previous presentation you mentioned the information available from drill reports ect. Perhaps if find time you could do more in depth talk on how to find these reports and obtain the data in them.

Thank you you answered alot of questions.

Hi Bruce that was a excellent video thank you cant wait for the next

Like your information just getting into prospecting understanding where to find gold and understand geology.

Great. Learning a lot of stuff

Thank you for this information.

I've crushed and tabled many tons of beautiful brecia here in Arizona seems to have similar geology to areas of Australia but I find little gold so far I would love to live near the Australian gold field great video thanks.

Bro I subscribe. How can I not when Russell crowe's teaching me about precious metals ! 😂😂 Awesome video dude, How many times have you heard that in your life... Keep it coming Man I'm loving your content

Thankyou for sharing your good information .

Thanks a lot for all these golden scientific informations your brother from morocco

Cheers thanks for your incites!

Great explanation. Makes it clear that the earth is no longer in a state favorable for new gold deposition, and what we find is only from being placed during the planet's infancy. Also a great visualization as to why the fault strikes alway occur on an angle.

Could I suggest to you that quartz turns into gold due to its interaction with cosmic energies that are constantly bombarding and travelling through the earth. Quartz over a long period of time turns into gold.

Nice work Bruce

Super educational! Thank you.

Awesome stuff, well done 👍

Lightning strikes can turn quartz into gold. Believe it or not!

Thanks for the great information. I believe that most reefs run in a North - South orientation. Is this true and if so, why does this happen? Thanks, I look forward to watching more of your presentations.

Never knew a Seth Efrican who was so helpful. Well done, excellent presentation. ✅

Great video ,

I haven't seen all your videos, but would like to see one, where the Au forms in Shales, with a Carbonate gangue.

Excellent video, thank you. May I ask why adding Iron to the solution causes the gold to precipitate? Does it 'simply' change the phase diagram of the solution and so at given themperature the gold starts to solidify, or is there some other reason?

Monzanite intrusions and as it cools in the zones thats where you get that juicy shiny.. slicknslides clay zones into Argilic alteration zones, porhyritic zones, in replacement series, manganese, iron, copper, sulphur Arsenic etc, in contact with carbonate zones , roses, bands in quartz episodal growth series. But i know you know all that. I find it all fascinating.

You didn't mention the importance of subduction zones of ancient water loaded sedimentary rock, high pressure superheated water dissolving minerals, crystallization of minerals out of that hot solution not magma and injection into rock above

Fantastic!

Thanks great job.

Thank you!! 💛💙

Hi again Bruce, just a question.What has more important reference to a gold location on the top of the surface,a fault or a shear zone .Thanks Greg

It's helps me, of some how valuable stones come s from Jamaica wi, and seems some amount of goals as it's fine will tell s.

Thankyou very much! i have to do more reading. Any suggestions on books?

My friend has few acres n rocks all white few black lines other rock a little brownish/orangy color one is 33 lbs. Lots smaller rocks too at ground some lg flattish rocks protruding other areas. In Lancaster Co pa. Should he look deeper?

Are you talking about a greenstone belt hosted gold deposits like Abiibi in Canada?

Hello my teacher I want to look for gold. I came across quartz stones, but I'm not sure if it's gold. How can I be sure?

Now when all that gold over millions of years washed into the sea, since its very heavy is it at the bottom of the sea? like the bering sea?

So if I want to use a "Your mama so fat..." joke on someone who knows geology. I can say "Your mama so fat - she comes last up the fault line" right? Bad jokes aside thanks for the content. Very informative.

Now when the quarts moves up into the crack is it liquid? Is it soft. or is it solid?

Is it because of mineralization of the hot crust squishing molten gold around

Cool

Gold is very rare 3 parts per billion .

Ouch so 20 minutes until we get the answer to why gold forms in quartz?

Ta

Not to pick you out of geologist because I laugh at all geologist or anyone else it says it took Q billion or 5 billion or 1 billion years that developed in that take place when it's not observable nontestable and non-scientific to say that it's all speculation and I guess when we canthe processes within hours in a laboratory which you and other geologist most or what the other ones are saying without giving it any thought no it didn't take that many years at all it took hundreds of years maybe billions of years

The thing obvious is the bs

The first thing that struck me was that you know very little about geolgical processes. You used the term suck up when speaking about movement in a fault zone. Have you had any education in geology? You also do not comprehend what differentiation is. When geologists speak of differentiation in magama chambers we are talking about minerals that crystalize from the magma and either sink or rise. But you seem to be talking about elements like Au, Ag, Cu. They have nothing to do with crystal differentiation. As minerals like olivine, pyroxene, and plagioclase start to crystalize, they form with very few trace elements in their structures. This concentrates elements like Au and Ag in the magma. You do not appear to be familiar with Bowen's reaction series. You talk about quartz being at the top of the magma chamber because it is light. Well that is not true. Quartz is the last thing to form. Si which is a major component of quartz (the other being O) is concentrated in the magma as the other minerals in BRS settle out or rise to the top (plag up and OL PX down). Not only is Si being concentrated but other elements/compunds are also - such as Au and Ag and water. It is the water that carries the Si and precious metals into fractures. You don't necessarily need faults either. This is the reason why you have quartz forming with gold. It is carried in hydrous fluids and deposited. Good lord. And I suggest you go and learn about orogenic gold deposits which are probably not formed from magmas but metamorphism with hydrous fluids. You should not be making videos because you read a book. I stopped listening after the first 6 minutes so maybe you managed to get a few things right after I turned it off. you seem like a nice fellow but a geologist you are not.

gold is heavy and have nothing to do with gold going up! Gold is in our blood, so when you die the gold in your blood will go to the lowest part of your body to the ground! There were Giants in the Earth! Read the bible, the word of God!

no one knows, that is the beauty of science fact,thre is no 100 percent certanty!
