摘要
地球化学异常的分布受制于一定的地质构造环境,不同的元素含量(或异常)分布特征,反映着不同岩体、地层及火山作用、断裂活动的特点。以1∶20万区域地球化学资料为基础,开展基础地质研究对地质找矿具有重要的指导意义。
Geochemical anomalies in desert are controlled by certain geological structures,and different distribution features of radioactive elements(or anomalies) reflect characteristics of different rocks,strata,volcanic activities and fault actions.Fundamental geological researches on the basis of data obtained from 1∶200 000 regional geochemical survey are of great guiding significance in geological ore-prospecting work.
