摘　　要：桂北地区分布有大量的层状侵入的基性-超基性岩体,清明山岩体是出露最大的基性-超基性岩体,出露面积20 km2以上。对该岩体的区域地质背景、岩体地质特征、岩体的岩石地球化学特征等研究表明,与金川超基性岩体相同,即存在岩体底部就地熔离型浸染状矿体,也存在深部熔离贯入型块状矿体,岩体具有很好的岩浆熔离分异作用和成矿性,找到有一定规模的贯入型富矿可能性较大。There are many layered basic-ultrabasic intrusions in the north Guangxi area.Qingmingshan intrusion is the basic-ultrabasic rock body with the largest outcroped area.（over 20 Km2）.Research on the regional geological setting,geological feature and general geochemical characteristics of the body show similarities between it and Jinchuan ultrabasic rock body,i.e.in-situ magma partition of the disseminated ore bodies at bottom of the rock body and magma partition and injection of massive ore bodies at depth,The rock body is potential for development of injection of rich massive ore bodies.
