摘　　要：塞拉利昂中北部Makong地区位于西非克拉通—苏拉山绿岩带内,地处苏拉山绿岩带的中部,该区成矿条件有利,金矿资源丰富,砂金矿是该区主要矿床类型之一。对Kangari山绿岩带开展原生金矿勘查找矿工作,是一个更为重要的找矿方向,也将会获得更大的找矿成果。在Makong地区以先期寻找砂金矿为切入点,最终以寻找岩金矿取得找矿突破,即实施砂金—岩金综合找矿,在该区是一条经济可行的勘查思路。Makong in the middle and east of Sierra Leone is located in west Africa Craton--in Sura Mountain greenstone belt,and in the middle of the Sura greenstone belt. The metallogenic condition of this area is good,and the gold deposit is rich. The placer gold is one of the main deposits of this area. It is a more important prospecting direction to develop exploring and prospecting work of primary gold deposit of the greenstone belt of Kangari Mountain, and bigger prospecting finding will be made. In Makong, finding placer gold deposit is firstly looked as starting point, at last finding the rock gold ore is looked as the breakthrough of prospecting. That means to carry out comprehensive prospecting of placer gold - rock gold is a feasible and economic exploring thought.
