Thanks Phil! Yes, mine dumps are a great place to find stuff. And the geology of Scotland is very interesting. Lots more going on than here in England.
Awesome, thank you. As for green copper, often the layer on the outside is malachite, which is, I believe, an oxidation. Also, the patina on bronze statues is technically malachite. (It is not, however, the same as rust on iron. The patina actually protects the bronze, whereas rust of course does not protect iron based material.) As for calcite, I have become cautious because it looks very similar to dolomite. A hardness test can distinguish between them.
Yes, it is malachite for sure. As for the calcite, it might be dolomite as you say. It seems pretty equal in scratch tests to some calcite I had before (but that might be dolomite too!). No glass scratch so definitely not quartz. Not much fizz from weak acid either, which suggests maybe dolomite. It could be not naturally from the area, brought in with limestone as a reducing agent in the furnace.
@surreygoldprospector576 Here is a video I made recently on dolomite vs. calcite. Your acid test is also useful, but I don't have any relevant acids myself. th-cam.com/video/IhcBRV4b9Y0/w-d-xo.html
@@spiritualpathseeker Thanks, that was useful. They are pretty similar, so difficult to tell apart. I have a box of calcite that is probably a mixture of both.
Great vid, Checkout Mindat for that location, it may help identify the other minerals. And checkout a book called Minerals of Scotland by Livingstone. The green mineral is likely to be pyromorphite, a lead secondary.
Thanks for your comment and the information. I took a look at Mindat and it was very interesting. There is a lot of mining history in that location. It listed 56 minerals found there (of which 25 copper-based ones) so didn't help narrow down much, but a great place to have a rummage in the rock piles! I didn't mention it in the video, but I now suspect a lot of the rocks I found had been through the smelter (or at least the crusher) so may have been altered from their natural state.
👍🙂 Enjoyable video, thanks for posting.
Thank you!
You did really excellent you got some nice specimens of rocks good job my friend

Fantastic Stone and Mineral. 😊
Thank you! Grazie! :o)
@surreygoldprospector576 Thanks to you, always a pleasure to meet another enthusiast. 👍
Love the video! Cool rocks you've found!
Thanks mate! Lots of interesting stuff around mine dumps.
Great specimens at the end!
Thanks!
NICE ONE BRO THANKS FOR SHARING 👍👍
Thanks Chambo.

Was the pyrite or gold deposits on the quartz? ⚒👍🤠
Sadly, not gold!! :o( I think it was Bornite on the quartz, which is a form of pyrite with copper as well as iron.
@@surreygoldprospector576 thanks for the information. I was blinded by the yellow shine 😆
@@Ltn.Immelmann Ha ha, yes I like the shine too! If it was gold I would be a rich man now!
