在德合龙洼矿区地表按一定的网度采集了1 228件地球化学样品,分析了20个微量元素含量,根据各微量元素的地球化学性质及其与成矿元素的相关关系进行了多元素异常组合的划分,分析了该区地球化学异常结构模式.研究表明该区地球化学异常结构模式与实际情况基本吻合,区内发育有3条构造破碎带,本区的岩浆活动以及矿体的产出均受这3条构造破碎带的控制,构造破碎带是本区进一步开展找矿工作的重点地段.%1 228 geochemical samples were collected according to a certain grid in the surface of Dehelongwa mining district, and the content of 20 trace elements was analyzed, by the geochemical properties of each trance element and the co-relationship between each trance element and ore-forming elements,abnormal combinations of multiple geochemical elements were divided,and the abnormal geochemistry structure mode in this area was analyzed. The research shows that the abnormal geochemistry structure mode does consistent with actual situation in this area. There were three structural broken belt were developed in research area, the magmatic activities and forming of ore bodies were all controlled by this three structural broken belt So the structural broken belts are the important areas for the further ore-prospecting work.
