Document Summary
3 of bierman and montgomery (last chapter in coursepack)) Silicate minerals most suscepible to weathering and the one least suscepible to weathering, and why. Sequence of weathering of the upper earth"s crust (most of which is feldspars) . Quartz is the most resilient mineral to weathering because it is the most stable mineral at earth"s surface and because its hardness and lack of cleavage is resistant to physical weathering. Be familiar with the two essenial carbonaion/carbonate reacions: . and how shiting the irst reacion one way or another will cause the second reacion to shit one way or another. Shiting the irst equaion to the right will increase h2co3, which would cause the second reacion to shit to the right to balance the increase of h2co3, which, in turn, would increase caco3 weathering. Saprolite (sketch): saprolite occurs where weathering > erosion.
