Epithermal Quartz Textures

[@MrGoblin60]

Thank you Nick. You managed to cram a range of geological terms and some botany into a comprehensive three minutes. My kind of lecture.

[@GeologyUpSkill]

Video editing consumes a lot of time. I dont like to waste it with filler!

[@lachlanscanlan5621]

what a magnificent rabbit hole these epithermal systems are, the questions are endless. I have many intrusion (granitoid) related gold systems in my area. They appear simpler than these epithermals which are also in the area, and yet even there after 20 years most of my questions about the metal genesis and contact alteration, relationships between rock types, never seem to resolve. I need another three of me to gain the time.

[@GeologyUpSkill]

That's what keeps geologists employed!

[@mustafa_mohammadpoor20]

Very good doctor Tate 👌

[@GeologyUpSkill]

Thanks Mustafa.

[@gavinkalaher7314]

Love a bit of epithermal. Very nice textures.

[@GeologyUpSkill]

Yes indeed. Especially in a new discovery :)

[@gavinkalaher7314]

@@GeologyUpSkill congrats, great discovery!

[@richardhaselwood9478]

Thanks Nick. Great to be reminded of this stuff decades after I left uni ;)

[@GeologyUpSkill]

It all comes back when you stumble across a new one :)

[@mayramuzo1756]

Thank you for sharing!

[@GeologyUpSkill]

Thanks for taking the time to comment. It helps KZbin to share the video with people who will enjoy it.

[@braydenst.pierre9761]

Another great video. Thanks for sharing!!!

[@GeologyUpSkill]

Thanks for taking the time to comment.

[@brunoandrenacci3466]

Thanks Nick

[@MerchantMarineGuy]

Great info, very helpful!

[@GeologyUpSkill]

Great. I hope it helps you to find something similar.

[@geoffgeoff143]

Wonderful

[@GeologyUpSkill]

Thanks!

[@jdean1851]

VERY EXCITING FIND and SAMPLES!

[@GeologyUpSkill]

Agreed. Not often you find something like this without any sign of previous work.

[@robertnewland90]

Looks similar to some outcrops near my house in the rural area of Darwin NT.

[@GeologyUpSkill]

Better grab some samples then!

[@robertnewland90]

​@@GeologyUpSkillI will do, crush and pan technique for sampling you reckon?

[@GeologyUpSkill]

That is the fastest way and will get a result in 90% of cases.

[@GeologyUpSkill]

That is the fastest way and will get a result in 90% of examples.

[@phaithoonvongsinery893]

Very clear sir

[@GeologyUpSkill]

Thanks. I try to make videos that show important things clearly.

[@Coltbreath]

I want to just geopick on that outcrop

[@SenorTucano]

Leave no outcrop behind!

[@GeologyUpSkill]

Yep. It's hard to walk past those if you still have some empty sample bags in the backpack.

[@zenatrue7613]

Fascynating!

[@jacksprat9972]

A+.......Great job. You rock, LOL

[@jdean1851]

WHAT a GREAT REVIEW" WHEN/IF? I EVER GET 2 SEE "THOSE TEXTURE'S" in the FIELD ...I'll probably "PASS OUT" AMAZING SHARE! THANKS" from the Clearwater Embayment on the Colombia Plateau-IDAHO! jd

[@GeologyUpSkill]

Keep your eyes open. I'm sure there are plants in Idaho that also indicate copper and base metals.

[@afandipolontalo5759]

It would be great if you could visit and discuss deposit types in Indonesia

[@GeologyUpSkill]

Thanks. I actually worked in Indonesia (Sulawesi) many years ago but it was before I learned how to make video.

[@afandipolontalo5759]

@@GeologyUpSkill That's amazing, I'm also a resident of Sulawesi. Sulawesi is an island with a complex geological structure, as well as a location of diverse hydrothermal deposits. May I know where in Sulawesi you worked before? I hope I can meet you someday

[@GeologyUpSkill]

@@afandipolontalo5759 I worked on the Wonggahulu and Petulu porphyry prospects and later on the Bulagidun breccia.

[@Aurelius-el3rn]

Can I ask why Rhyolite is not a suitable host for epithermal systems? Not a geologist but have an interest in mineral forming systems and was just wondering the logic behind that

[@GeologyUpSkill]

Igneous systems with rhyolitic composition seem to contain less gold so there is not much to leach out and precipitate in the epithermal veins, but it is not an absolute rule. There are some exceptions, particularly in systems with a mixture of rhyolitic and andesitic volcanics.

[@sagebryant902]

Hi Nick, great channel! could you share your thoughts on something please? I want to pursue a career in geochemistry here in Australia and its almost time for me to finalise my university major. I am having a hard time deciding what degree would be most beneficial for this type of work, do you think a chemistry degree with a geology minor or a geology degree with a chemistry minor would best equip me with the fundamental knowledge/skills needed to be a good geochemist?

[@GeologyUpSkill]

The simple answer is to major in the subject you enjoy most. Chemistry is probably more useful to a geology career than geology is to a chemistry career, but if you love what you do, work will seem like play.

[@Zloner]

Hey Nick, How would the texture reflect the fluid's boiling conditions? (Pressure-Temperature conditions?) If this question is too broad for KZbin could you recommend any papers on the subject? I am a PhD student and I am studying fluid inclusions in quartz veins just to get that out of the way.. Great video! Alon.

[@GeologyUpSkill]

Most of the direct evidence comes from textures observed in systems drilled for geothermal energy where the boiling is still active. Try searching that area of literature. Lots of work done in Newzealand.

[@phaithoonvongsinery893]

Hi,​ex-old boss. Could you remember​ me? Nices​ to see you sir.​

[@GeologyUpSkill]

Ye. How is Lao exploration industry?

[@taylorrose5760]

Could this be a area where free gold occurs?

[@GeologyUpSkill]

Yes. Low sulphidation veind often have free gold in the oxide zone, but it is usually fine grained.

[@GeologyUpSkill]

Thanks. My Australian accent is a bit thick, but if you turn on autogenerated captions, KZbin will sort it out for you :)

[@dolobatheophilekoivogui9227]

@GeologyUpSkill spite of the that I'm not a native english speaker, I often get a couple of things from your tuto including: 1-scientific and technical geoligical notions. 2-not only I'm getting used to australian accent but also achieving new geological glossories that strengthen my geological and english skill. Therefore be blessed
