Abstract

The AA. examine a granitic, soil-mantled hillslope at Point Reyes, California, where soil production rates were determined using in situ produced cosmogenic nuclides (Be 10 and Al 26), and they quantify the extent as well as the rates of chemical weathering of the saprolite from beneath soil from across the landscape. They collected saprolite samples from the base of soil pits. The results show for the first time that chemical weathering rates decrease with increasing soil thickness. The AA. also show that spatial variation in chemical weathering appears to be topographically controlled
