I've learned more about copper minerals and minerals associated with them in this video than I have learned in the past 40 years in rock hunting! Detailed/clear/no nonsense way of teaching a audience about geology/rocks. SUBSCRIBED!!!!
@@GeologyUpSkill Great point. Keep up the EXCELLENT work. I crave what you know, (on the subject of Geology) just like millions of others out there in TH-cam land.
Black looking oxides can also be tested for copper by scratching them to form a powder, adding a drop of HCl, then mixing it with the clean tip of a standard metal nail where the copper will plate onto the nail.
Great video, thank you. I have a question, is it possible to find secondary minerals like malachite directly associated with a primary mineral like chalcopyrite?. Gretings from Ecuador
Yes it is possible a little above the water table where chalcopyrite is only partially oxidised, but most locations at surface the chalcopyrite is completely oxidised away and you only see malachite and some boxworks where the chalcopyrite used to be.
Real ones will go to the link in the description and purchase the Fieldcraft for Geologists course. Nick Tate is a towering Golden God. We are not worthy!
I much appreciate those who purchase the fieldcraft course. Every one of them helps me to make more videos and that helps to bring the free versions to thousands of people who don't have the resources to learn.
One of the great things about TH-cam is that there is no limit to the number of students who can benefit from the knowledge you share. Offline teaching is more fun, but the reach cannot compare!
I don't have this course accredited for professional development since it is just a random collection of the useful things that I find in the field. Perhaps I should make it more complete so it could become certified professional development, but that would make it more expensive :(
I definitely enjoy the channel. Having a couple semesters of Chemistry and a Geo 101 make your presentations even more positive. These videos certainly enhance my prospecting adventures and general knowledge as well. Keep up the excellent content. Thanks.
Budding geologists: decent crystals of azurite, chalcocite, and cuprite are highly valued by collectors, and malachite and turquoise are valuable gemstones. If you find interesting specimens in your travels, get in touch with a mineral dealer. Good specimens and cutting material can be very profitable to mine, even on a small scale. A single outstanding piece can bring four or five figures. Don’t send them to the smelter for ten cents worth of copper content!
That conundrum has always been an issue for mines. Many of them prohibit mineral collection because they fear it will result in a conflict of interest for employees and a danger for visitors. One exception in my experience was the Zaaiplaats tin mine in South Africa (now closed). They actively mined specimens in large vughs in the host granite. Many 5 figure museum quality specimens came out of that mine.
Bonjour mr je répond au nom de heritier kamwanya, juste pour savoir le prix pour le vidéo il y as que des vidéo ou bien il y 'aurais aussi un certificat de cette formation ?
Pour l'instant, il ne s'agit que d'une collection de vidéos. Vous pouvez choisir ceux qui vous intéressent. Vous n'êtes pas obligé de les regarder tous pour obtenir un certificat.
@@heritierkamwanya71 La plupart des formations de premier cycle menant à un diplôme en géologie se déroulent dans les universités. Si vous avez déjà obtenu un diplôme de géologue, recherchez des cours proposant un développement professionnel certifié (CPD).
This video was shot on a November morning. If you look closely at some of the shots, you will see the rocks shimmering due to heat distortion of the air between the specimen and the camera.
Knowing your in the Mount Isa area. Wondering if any turquoise has been found in Phosphate Hill area? Can you do a video of the Schist and staurolite (Maltese cross) area south of Mount Frosty? Found abundant examples of the same minerals in your video many years ago at the Hard Rock mine halfway between Mount Isa and Mary Kathleen. Was near the Aboriginal Sun Rock site.
@@GeologyUpSkill Small Uraninium deposits North East of Lake Moondarra. I know this because of a geology field trip with Geiger counters when I was a kid. They area was more low rolling hills with basaltic outcrops compared to the steep rocky hills closer to Isa.
I've noticed a yellowing on large boulder of malachite. I even found a chunk of this yellow rock that was hard & solid enough to polish. Due to it being heavily silicified. Rare. As most of is crumbly. My found piece really took a good polish. A bright sun yellow. I keep trying to find more of it ha. Does limonite form on these copper type of boulder? Any idea what yellowing is? Thanks
Harder yellow oxide minerals are often jarosite that commonly forms where there is lots of pyrite beneath the weathering zone. Mixtures of jarosite and silica can make them hard enough to take a polish so I suspect you are correct there.
Thanks for mentioning jarosite Never heard of it A picture on the wiki page Sure does resemble my piece I visited your web page Maybe during the summer months When hounding is off limits Due to nothing butte hot rocks I can join sure do hit on many of the types of geology I explore Thanks
Thank you for the very good information. I am learning about the copper ores that I am finding in the mine tailings piles. Your video quality and clarity was awesome.
By weathering of primary copper minerals (most commonly chalcopyrite). How those primary copper minerals got in to the rock is a long and interesting story which is why I studied geology!
Learned alot on this video. I found some copper precipitate mixed within a predominant vesicular basalt groundmass several months ago and decided to take it out of storage and examine it more closely in my lab. I'm going to attempt to extract the copper from the basalt. Should be pretty interesting whatever the outcome. Great video!!!!
Just occasionally, vesicular basalts contain native (metallic) copper. You can usually only see it in a fresh broken piece because it gets coated in green secondary minerals after it has been exposed to the air for a while.
@@GeologyUpSkill specimens we're retrieved in an area of a predominance of rhyolite. It's a mountain region with an oregeny of 24-36 million years old (Oligocene/Miocene). After failure of obtaining no copper sulfate precipitate in samples I placed some of sample from the bottom of beaker onto a microscope slide. I observed grains of isometric/cubicle in shape (possible rhyolitic groundmass?) Instead of a misdiagnosed basalt? I based my beginning statement as a 'vesicular basalt' sample because of observed filled cavities of green colored material. Another hastily mistaken observation it would seem. Other microscope grains observed threw the microscope were what appeared to be grains of peridoitite? Red colored grains as well.
@@GeologyUpSkill in the end the quartz grains in the micro sample had me leaning towards a rhyolite with some unknown green material imbedded within the greyish colored groundmass. Whole specimen displaying as a porphyry.
@@themainediverschannel4495 If it contains quartz grains then it is more likely to be rhyolite than basalt. The greenish grains may be chlorite which contains no copper.
There is an old saying about gold specimens: "If there's any doubt, there's no doubt". Meaning that when you see real gold, it is really obvious. If you are at all unsure, then you can be certain that it's something else.

Yep, that trick is explained in the full version of the video.
Just bag it and have the lab analyze. No muss no fuss!

Green is good!
Hello, can you do one with regard to coltan and minerals associated with them please
If I work on a project with coltan I certainly will.
What about the ones that looks completely greyish but heavy .
That is most likely chalcocite.
@@GeologyUpSkill I wish I can send pictures
hello sir, please how to have the videos, then is it certified or is it just the videos? because I need all this knowledge
I don't have this course accredited for professional development since it is just a random collection of the useful things that I find in the field. Perhaps I should make it more complete so it could become certified professional development, but that would make it more expensive :(
Here in Butte Chalcanthite and other copper sulfates can be easy to confuse with azurite. They are water soluble and will not react with HCl.
That's true. Chalcanthite is also a little softer than azurite, but difficult to determine in small crystals.
Brochantite, antlerite, and melanterite are also commonly mistaken for their more famous cousins.
@@blackpowder4016 usually some atacamite also if you have that set.

Thanks very much. Every subscriber is appreciated.
is there a website with pictures that list the gaps/holed that signify what mineral is being leached?
The best resource for that is a book Gossans and Leached Cappings Field Assessment by Roger Taylor

short but very informative :)
as a young professional geologist who loves minerals and exploration geology this video is very helpful and inspiring
That's great. I trying to inspire more geologists!
I have
Great!
How hot is FNQ at the moment? The Bowen Basin is hot enough, don't want to think about Cloncurry/Mt Isa

Hey Mr.Nick
l am a geologist from Egypt and hope to contact with you... You are a great geologist
