    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!

    Tour de Force! Incredible scope - from a subterranean furnace past, through the present and then from that intellectual promontory, look into the future. I have to watch it again, impossible to catch all the fascinating geological picture in one viewing. 👏👏👏😲💢

    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

    Thank you for producing this interesting video. The way you and others have worked out where all the rock types originated off what would have then been the South of Gondwana (where Madagascar is today) is very impressive. So too is the story of their metamorphosis.

      Thanks - the fundamental research laid out in the film was obviously done by others - but putting the story together is interesting. It was a nice prelude to my films on Morocco and on the Rio Tinto stuff...

    Very insightful in terms of magma emplacement and evolution. Thank you and nicely done!

      Thanks - glad you enjoyed it. Hope to get more minerals and tectonics videos together in the coming months.

    Talk of regulation is rather optimistic given the exploits of corporate profiteering in evidence to day. Thanks for the trip down memory lane which was the 1970's for me.

    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

    There is so much pseudo geology on You Tube, this is super and useful

    - the duchy is not in England , never was and and never will be 😂

    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.

    • @robbutler2095
      @robbutler2095  5 місяців тому

      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 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....?
