福建同安水洋预查区水系沉积物测量地球化学特征及找矿前景

Geochemical characteristics and prospecting potential of stream sediments in Shuiyang pre survey area of Tong’an,Fujian Province

通过对同安区水洋预查区1:5万水系沉积物W、Sn、Mo、Bi、Cu、Pb、Zn、Ag、As、Ba等10种元素测试数据的统计,总结区内地球化学特征,认为Mo元素富集、变异系数较大,在测区地质、地球化学作用强烈,元素迁移、富集特征明显,是该区内主要成矿元素;该区找钼多金属矿前景较好,存在巨大的找矿空间。

Based on the statistics of the test data of 10 elements(W,Sn,Mo,Bi,Cu,Pb,Zn,Ag,as,BA)in the 1:50000 stream sediments of Shuiyang pre survey area in Tong’an District,the geochemical characteristics of the area are summarized.It is considered that Mo is the main metallogenic element in the survey area because of its strong geological and geochemical action,obvious element migration and enrichment characteristics,and its enrichment coefficient is relatively large The prospect of molybdenum polymetallic ore is good,and there is a huge prospecting space.
