I've watched them all several times. All it took was coming upon a bunch of garnents in mica schist when I was out working and fell in love with rocks and had to learn 7th grade science all over again and boom this has been the best series. The only series without a bunch of astrology like crap telling me that this Rock's going to heal this and what not.I just like pretty rocks.
Greenstone/schist belts or rather metasediments that have made their way or exposed at surface is where I find my gold. If I can find Plio/Pleistocene metasediments that are implications(movements/exposure) of the late Miocene that are non-marine/lacustrine.... bam!.... there’s gonna be gold in it. But that’s just my local western Mojave Desert.
