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

@@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

Thanks. Breccia recognition is a much under-rated skill.

As far as I understand, a phreatic breccia is the result of an explosion from overpressured groundwater (probably due to heat from a distant magmatic source). They typically contain a mix of wallrock and vein clasts, but no evidence of igneous magma. A magmatic breccia is one resulting from movement of magma breaking up surrounding rock (not necessarily involving any fluid). They just look like an igneous rock with lots of xenoliths. A phreatomagmatic breccia results from direct contact of magma with groundwater. They look similar to phreatic breccias, but have some clasts of igneous material and sometimes infill of igneous material between clasts.

Thanks. Much appreciated.

If you want people to accept your advice, it's a good idea to make a video that explains the benefits of that adice. Renaming your youtube channel to something other than "Shuddup Yakunt" would probably help.

Yes indeed!

The areas of granite previously got little attention. Suddenly they are a potential host.

@@GeologyUpSkill Thanks Nick!

Thanks. Hope it helps you to make a discovery.

No he trabajado en muchos de esos. ¡Si lo hago, ciertamente haré algunos videos!

It is pretty tricky, particularly if it's fine grained. If you see a rock that looks like beige coloured marble in a system with lots of clay silica and pyrite, it should trigger suspicion.

@@GeologyUpSkill it has the added problem of being associated with the bonanza grades the old timers chased... I'm yet to find that too.... It's a MS overprinted by a LS driven by Cretaceous breakup of east Gondwana and now over planted with yummy apples.... It's been flooded and unexplored since 1903.... Until Patreon got me a ROV.... ua-cam.com/video/6Zng9u1Wv0k/v-deo.htmlsi=YK4gUnioz3JZFBGc

@@GeologyUpSkill it's the salmon coloured crystals that caught my eye as maybe it's not a feldspar...

If you can see good crystals, alunite is distictly tabular and occasionally in slightly radiating groups. Feldspar crystals are more blocky. Salmon pink could also be rhodochrosire in intermediate sulphidation epithermals.

@@GeologyUpSkill I'll look out for MnCO4 thanks ....hardware store HCl is my best friend and makes the UV phosphorescent calcite easy to spot... Fluids came up between felsic gneiss and ultramafic-amphibolite which was already hosting orogenic pegmatites. Cool Epithermal Muscovite and tourmaline pseudomorphs... I'd love to see you discuss komatiite vs bladed metamorphic olivine because this is mixed up in it too 🤔... Thanks for the great videos 👍

It works!

Breccias are always interesting rocks!

Lumpy surface without the usual flat surfaces created by joints.

@@GeologyUpSkill Okay. Thank you.

The flesh of the animals decayed, but the bones were remarkably well preserved in extraordinary numbers.

Machines make mistakes just like humans. Those mistakes are opportunities for those who work differently.

Agreed. One of the best I have seen.

Best to connect with me on Linkedin.

Experience is the most valuable thing you own!

Thanks very much.

Next video coming soon!

@@GeologyUpSkill Great, thanks!

Here it is :) ua-cam.com/video/1j3_GiR7HNM/v-deo.html

@@GeologyUpSkill Thank you Nick.. what you are showing is a feeder zone below the core of the porphyry orebody .. is that correct ?

None that I was sure about. Certainly a lot of sampling required!

I thought so too. Hence the video!

Thanks. B-Veins are very useful things :)

Yes. What do you need to know?

Residual since all of the soil material is derived from the rock beneath.

Thank you. That makes sense.

Those dumps are from a copper mine :)

It's amazing how much good stuff there is here!

The good stuff is always well hidden!

Thanks. Work really finds you in this industry. You just have to put the signposts in place for it. Most of that is about getting to know people who will be future employers. Working a lot of shorter contracts does that best, but traditional "networking" and now social media posts that highlight you particular skill set are a great addition. This video covers the basics ua-cam.com/video/qOYiMx8ctFQ/v-deo.html

It would be good farmland if it wasn't -40 degrees in winter!

@@GeologyUpSkill Ha ha ha, but so true.

Most of the historical placer work was done without explosives and with a minimum of infrastructure, although I have seen some where long contour channels were cut to bring water from higher elevation to run sluicing operations.

That's pretty much the approach, but alteration mapping is really helpful to put all of that other data in context.

True. Both disciplines are useful to each other.

Yes indeed. There are hamster holes everywhere here!

Congratulations on your vast army of research assistants .

Thanks very much. I learned quite a lot putting that video together :)

Learning from history can save you a lot of time!

Life was different then!

Well back then when the earth was much hotter with higher C02 levels the rates of CO2 fluctuations were at which organisms were able to adapt and evolve to climate change. Basically enough time for the the oceans to absorb CO2 to maintain an equilibrium in the atmosphere, enough time to suck CO2 out of the air through the weathering of rocks, and enough plants to absorb CO2; all these mechanisms relatively not disrupting plant growth and life.

Thanks, but I am not on UA-cam to make money.

Good strategy!

Both of those pursuits are great for networking and not so great for your liver!

Hopefully I will find some more people who know their stuff very well and are prepared to sit in front of the camera!

Thanks. Much appreciated.

Yep you have to enjoy learning. It's a pretty steep curve at first.

That advice is certainly valid. I managed to chip the back blade of one test hammer by hitting it into a crevice in a hard quartz vein at an angle, but striking with the hammer angled slightly to the right or left will contact along he full length of on edge of the face. I have never chipped a front face using that technique, but it certainly breaks rock much more effectively than a regular hammer. I also trialled a stinger for a while, but I found it was prone to spin violently if I mis-hit my target (because most of the mass is near the centre of rotation).

Whenever I see something useful in the rocks :)

I hope so. Exciting rocks!

@@GeologyUpSkill your very good at mineralogy, please do more on minerals and their alteration over time. This is something lacking in undergrad courses and up.

Actually I have a series on basic mineral recognition in the field currently in planning stage. Hope I get time to work on it later this year.

Rule #20!

Yes. A fantastic place full of big fluid systems.
