This is awesome multiplied by 1*10^35. Thank you. In year 1976 I found a chunk of metallic ore here 36.577383,-115.675902 but I had no knowledge what the metallic is, except that some of the content is a pyrite, until I watched this video. I kept that ore up to present day: it is sitting on my desk right now. It is chalcopyrite, probably from a gravel quarry, that was transported from the mine at 35.549194,-115.277748 to be used to "pave" dirt roads. Lucy Grey mine, Sunset District, Clark Co., Nevada, USA. Of course I could be wrong: I am uneducated. I worked a turquoise mine at 35.43028,-115.95639, living at another turquoise mine at 35.426276, -115.955615. Golly, that was a miserable job.

And it is common and cheap and makes up the core of US pennies. It replaced copper in this role when copper became more valuable in the 70's. Thank you for covering these deposition processes, and why zinc is often mined as a less valuable component in a more desirable ore.

The biggest zinc mine in Europe is the Tara Mines at Navan in Ireland. It was discovered in 1970 and is still producing 50 years later. The deposit is a variant of a MVT and is hosted in flat-lying Lower Carboniferous limestones. Silve and germanium are the two trace elements commonly associated with these Zn-Pb deposits, but other elements can be found in small quantities too, like the nickel in the Lisheen deposit, (Ireland).

Navan is great, I've visited there many times with students! A really well run operation and very interesting geology.

@@ourmetallicearth What interests me is where the metal came from, hydrothermal fluids rising yes, but are they leaching metals from sediments - the current theory? Perhaps there are VMS deposits or granites in the Lr. Palaeozoic or crystalline basement.

@ourmetallicearth 4 ай бұрын

I think the metals are believed to originate from the Red Beds that overlie the basement, but for sure if there are any deposits in the basement they could also contribute.

@karhukivi 4 ай бұрын

Yes, that is the current sedimentary-origin proposed. However, the Red Beds thin northwards yet Navan is the largest and furthest north. Bouguer gravity data shows the basement underlying the Midlands to be quite heterogenous, and not all the variations can be explained in the current horst & graben model.

Your videos are really good. I liked the manganese video a lot. It brings me to a question/thought I have all the time. I am a fan of caver youtubers, for example "Action Adventure Twins". They are always going to different caves and bringing their camera and posting edits of the trips. One thing that I always wonder about, but have no way of knowing, is how many of the caves they visit are also some sort of mine. Sure, a cave can form naturally, but once there is a way to access an underground area, perhaps miners would scout it, and if they found a vein, exploit it (just at some point in history) ... Or ,, in some other cases, perhaps miners were exploiting a vein, and during this, they encountered a cave. Well, I know for sure this has happened, and there are some examples that are unmistakable, but there are LOTS of times when I see a video, and it LOOKS like the manganese mine, but there's no way for me to tell if it's a natural cave or a mine, and the cavers always seem to just assume it's a natural cave. Another thing I always think about, particularly here in the US, is that so many mines may have existed illegally/undocumented. I always imagine some little group of people trying to keep a small mine a secret and then dodging their taxes, in the same way that the gold rush went down. I suppose someone very familiar with all of the ways a historic mine could look might be able to just see which passages are which , but I often can't help but imagine that perhaps some of the more "natural" passage are actually also some exploitation or some impact from exploitation. An example of this wondering is some of the flowstone,,, could it have been possible that use of chemicals to isolate minerals from ores and then the unregulated dumping of those acids/chemicals might have caused more rapid dissolving of rocks below the dumping grounds,, resulting in flowstone formations that could then be identified as this??

@ourmetallicearth 10 ай бұрын

Yes I think a lot of the caves are actually historic mines. It's quite hard to make a natural cave unless it's limestone or similar rock that is easily chemically dissolved by surface and ground waters. There are natural caves in limestones but also literally hundreds of historic mines in the UK alone that are now popular destinations for cavers.

Thanks for watching! If you mean gold nuggets in alluvial sediments, they are liberated from source rocks via erosion. I will do a video on gold at some point so that will hopefully give you all the info you need

Another interesting fact about zinc is that it can only be produced in supernovas. The fusion process in stars only produces elements up to iron on the periodic table. Zinc is a necessary nutrient for life. This means that if it wasn't for the phenomenon of supernovas we would not be here.

I have a friend who specializes in sphalerite in his mineral collection. It is a very boring and drab mineral in my opinion. Then again, he has little competition and can always get the best deals at the shows. In my line of work, a lot of ground water contamination is caused by leaking underground steel tanks containing gasoline. This can be prevented by attaching sacrificial zinc anodes to minimize the corrosion of the steel tanks. Unfortunately, the anodes need to be checked every few years, and a lot of station owners fail to do this.

Sphalerite is one of the most fascinating and beguiling minerals in existence. Under ultraviolet illumination it will fluoresce brilliant yellow and orange, sometimes blue, and depending on purity can phosphoresce for minutes after the light is off. It's also triboluminescent and thermoluminescent. It's a semiconductor with a wide band gap and has useful infrared properties.

I'm sure hoping I have a lot of zinc under my land! Zinc is one of the main metals found in my mining district.

@americanadventureoutdoors4213 Жыл бұрын

Nice 👍🏻 , not the main metal found in my mining district but there is quite a bit of sphalerite, interesting enough is that that sphalerite is carrying some gold in it . I find that interesting as a lot of people use zinc to capture gold when smelting !
