摘要
通过对辽宁区域岩石41种元素的区域分布研究,作者提出了辽宁岩石元素地球化学分区系统。依次划出1个地球化学省、2个地球化学区、12个地球化学分区及若干地球化学小区。以地球化学分区为基本单位,讨论了各分区岩石元素的浓集状况,指出了不同地球化学分区岩石元素分布的差异,分析了某些元素的富集趋势与成矿的联系。对探讨不同分区的地球化学演化历程,确定找矿方向,具有一定意义。
Through the study on the regional distribution of 41 kinds of elements in rocks from Liaoning, the author put forward a geochemical zoning system for rocks from Liaoning. The system successively includes 1 geochemical province, 2 geochemical regions, 12 geochemical districts, and a number of geochemical zones. Based on the geochemical districts as the basic unit, the concentration and differences of element distribution, and the relationship of enrichment trendency of elements with ore forming are disscussed in the paper. The zoning system greatly contributs to looking for mineral deposits.
