My ore deposits class was never this straightforward. I was constantly overloaded with minutia and struggled to grasp the big picture. You are an excellent teacher!

Academic research, by it's very nature, seeks more and more detail for the chance to make a discovery that has not been covered by previous workers. Occasionally that pursuit makes spectacular discoveries in science, but we entrust those same people with training new geoscientists who need to understand the big picture before diving into the detail. Only a few of them are able to step back and remember what it was like to see a phase diagram for the first time.

I've studied alteration halo's but never knew this. 🤔 There's a big leap in geology in field and in classroom.

Low sulphidation systems used to be thought of as a separate species, but it now appears that some of them are distal or evolved parts of the same fluid systems.

Thank you for the video. Your video is really helpful. I'm currently doing a research about High Sulfidation Epithermal deposit for my final assigment but I still can't determine which one is alunite and which one is pyrophyllite during my field mapping. I already took a lot of notes on how to describe and differentiate those 2 minerals from you video and I hope it'll be a very useful guide for me during my field work. Keep up the good work sir 😁

this maybe a silly question ... but canyou polish aluntie that mixed with sandstone ???
@GeologyUpSkill
12 күн бұрын
You probably could, but since it is a lot softer than the quartz grains in a sandstone, it would be difficult to get a smooth surface.

Dear, could you share with me a clear image where the pyrophyllite and alunite, of advanced argillic, are observed, that is, when it does not look crystalline, please!
@GeologyUpSkill
9 ай бұрын
The sample at 2:24 in the video is typical of pyrophyllite without obvious crystals in advanced argillic alteration systems. Alunite almost always shows some crystal reflections even when it is an alteration mineral (like the examples at 1:16), but they are much finer grained than the infill alunite in veins.

It commonly forms a halo around high sulphidation epithermal style gold deposits. That's a pretty useful guide!

is there a field test to distinguish sericite from pyrophyllite
@GeologyUpSkill
2 жыл бұрын
Sericite is basically a bucket term for white micas formed by alteration. Most of them have crystals large enough to see some reflections in the sunlight with a handlens, particularly on freshly broken dry surfaces. Even the really fine grained ones have a silky appearance that is different to the dull waxy sheen of pyrophyllite.

@@runnikcatti5997 OK, so the white patches are probably indicating acid groundwater leaching due to weathering of sulphide in the veins. Not original hydrothermal vents, but a good exploration indicator!
