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��
