Cornish granites - tectonics, metals and mining
Вставка

- Part of The Shear Zone Channel. Granites control the development of the World-famous Cornish metal province. This video visits granites near Land's End, to explore their structure, petrogenesis and the underlying tectonics. It's a necessarily complex, multidisciplinary story - one that leads into the sustainable development of some of the critical earth resources we'll need to make the transition to low-carbon societies. But the story has only just begun - there's lots more to find out about the tectonics and mineralisation.

Being a Janner that didn't learn too much in school I have aften wondered how the beautiful lands around us were formed. An excellent video!
Very interesting but a little top technical for me.
Great job on interpreting this complex geology.
You have a wonderful ability to describe, communicate and understand these geological processes
Thanks for all of your hard work
Glad you enjoyed this - thanks for the comment
Very insightful in terms of magma emplacement and evolution. Thank you and nicely done!
Thanks - glad you enjoyed it.
randomly stumbled onto this video having lived down in plymouth for almost 20 years now really interesting will defo look at granite differently when i see it on dartmoor or on trips down into cornwall
Thanks for the comment - glad you found the video useful...
We love our "environmental impacts" :-) eg. there's hectare-sized areas where no plants have grown in 170-ish years since mine abandonment. Okay it would be good if a new phase of mineral extraction could very much minimise "stray streams" and environmental effects.
Modern mining/mineral processing accompanied by tough (and enacted) regulation means modern mining can have very little negative impact... as you note - the historical examples leave a long legacy....
This was great! Thank you!
Thanks - glad you enjoyed it. Hope to get more minerals and tectonics videos together in the coming months.
Great video, only one bad point
- the duchy is not in England , never was and and never will be 😂
Apologies for the Anglo-centric commentary!
@@robbutler2095 You had no chance, we aren't recognised on the maps as anything but.
This is really good. I’m playing with the mid continent rift. I don’t have experience with rifts. I will.
I got someone to drill my Andean chile project. fun…but…14-16k elevations ahh..cliffs.
Anyway…Man heavy geochem and rock lithology. I have to go over this a few time and this is my professional specialty. Keep up the good work!
You might have a look see at my efforts to understand the role of anhydrite in generating copper in copper porphyries.
So why tin there and not elsewhere? Shouldn’t all S-type granites be good? I mean Colorado is full of S type with similar metamorphic units. Two mica granites all over the place in Colo. uraniferous peg’s etc….even lamprophyres. I think there is a story there.
Thanks for the interest - and comment! Role of "secondary" units in mineral deposits is interesting... the distribution of tin in these systems certainly patchy... does it reflect the types of country rock around the granites....?
Im excited for South Crofty to reopen. My Geology teacher just told us that they are applying for miners, which is really good for the area. The red river might finally be red again!
Yes - re-development the mining industry in the SW is great... though hopefully the environmental protections will be more robust. There's no need for the extractive industries to have the (negative) environmental impacts tat they have had historically...
@@robbutler2095 Iron oxides in the river aren't much of a negative. But you have a good point. Walking down the road and dying of arsenic or heavy metal poisoning is not great.
