Скачать или смотреть Part 2 Diamond Hill Crystal Formation at The Mine 2 for STMS

I have returned to Diamond Hill Mine to show you the open pit mine where I collected the specimen that is in the STMS library. Also, it show the drastic differences between 40 Acre Rock Heritage Preserve and Diamond Hill mine even though the origins of each are form the original formation of intrusive igneous rock. Both plutons formed from magma flows that cooled deep in the Earth.
40 Acre Rock was pushed to the surface where you see the current pluton exposure.
Diamond Hill Mine was a pluton that remained deep in the Earth and under went chemical weathering creating saprolite. The saprolite and Quartz Veins
were forced to the surface where you are digging through 400 million old material.
