中国大陆岩石圈层碳硫磷的库存量及分配

The CONTENTS AND DISTRIBUTION OF CARBON, SULPHUR AND PHOSPHORUS IN THE CONTINENTAL CRUST OF CHINA

根据中国地壳厚度的最新研究结果和近1600份中国岩石化学分析资料,计算了中国大陆岩石圈层中碳、硫、磷的库存量和在各岩类中的分配特征。并和国际碳循环研究计划所得的全球陆壳中碳的库存量结果进行了对比.

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.
