吉南—辽北地区太古宙主要地质单元的含金性研究

The study on the Au-bearing character of the main Archeozoic geologic unit in the southern part of Jilin province-northern part of Liaoning province

本文基于吉南—辽北地区３６４件最新的微金分析资料，表明各主要太古宙地质单元的金丰度均明显低于地壳金丰度值。同时指出，本区绿岩带有关金矿的矿源是多源的，其中有相当一部分来自于深源（下地壳或上地幔）。

The gold abundance of the main Archeozoic geologic units is obviously lower than that of the earth crust from the results on the latest data(364 pieces) through micro bulk analysis, indicating are of multiple sources on origin. Some deposits are derived from deep part(Lower crust or upper mantle).
