【Abstract】 Based on the recent research achievement on the thickness of the continental crust of China and the analytical data of around 1600 rock samples from all over the country, the contents of carbon, sulphur and phosphorus in the continental crust of China were calculated to be 7.67× 10(21)g, 1.47×l0(21)g and 1.51 ×10(21)g respectively. The reservoir content of carbon sharply decreases with the increase of the depth from the continental sediment compartment to the basalt compartment while the content of phosphorus increases. The largest sulphur reservoir is the continental granite compartment. 65% of the total carbon and 58% of the total sulphur in the sediment compartment are concentrated in carbonate rocks. On the contrary, phosphorus is equally distributed in various types of rocks.更多还原
