Jinchang gold deposit of Heilongjiang is a large rock gold deposit dominated by explosive brecciation pipe type mineralization. Taking the explosive brecciation pipe type J0 ore body as the main example, the authors discussed the geochemical characteristics of this kind of ore body through the geochemical analysis of lithological trace elements in six defferent levels. The results showed that among the twelve analyzed elements, the anomalies of Hg, As, Sb mostly occurred at the top up of gold ore bodies; the anomalies of Ag, Pb, Zn, Cu mainly occurred in the middle part of gold ore bodies; whereas the anomalies of Ni, Mo, W, Co are mostly located at the lower part or at the tail part end of the gold ore bodies. The distribution characteristics of the elements anomalies can be used as indicators for evaluating the gold-bearing features of the explosive brecciation pipes and predicition analysis of deep prospecting potential in Jinchang gold mining district.%黑龙江地区金厂金矿床是以爆破角砾岩筒型矿化为主体的特大型岩金矿床,以矿区J0号爆破角砾岩筒型矿体为主要对象,通过对其6个不同标高水平的岩、矿石微量元素地球化学分析,探讨了该类矿体地球化学特征.结果表明,在所分析的12种元素中,Hg,As,Sb异常多出现于金矿体顶部及上方;Ag,Pb,Zn,Cu异常主要出现于金矿体中部;而Ni,Mo,W,Co异常主要发育于矿体尾部和下方.这些元素岩石地球化学异常分布特点可以用于金厂矿区爆破角砾岩筒的含矿性评价及深部找矿前景预测分析.
