摘要
在1∶5万水系沉积物地球化学测量成果的基础上,分析了汎河凹陷东部下肥地地区的地球化学特征,认为研究区内寻找Au、Pb矿产潜力较大。结合区域地质背景,总结了研究区主要地质单元的地球化学特征,Pb在长城系三岔子群康庄子组和关门山组地层中有富集成矿的可能;Au在新太古代变质深成岩中背景极高,有很大的找矿远景,为区域地质、地球化学研究及找矿工作提供了重要的依据。
The geochemical characteristics of Xiafeidi area in east of Fanhe depression was studied based on the 1:50000 stream sediment survey.It was of great potential to find the gold and the lead ore deposits and mineralized bodies.Combined with the geological background of the region,the geochemical characteristics of the main geological units in the study area are summarized,the lead may be enriched and mineralized in the Kangzhuangzi and Guanmenshan formations of the Sanchazi Group of the Changcheng System,the gold has a very high background in the Neoarchean metamorphic plutonic rocks and has a great prospecting potential,which provides an important basis for regional geological,geochemical research and prospecting work.
