东乘公麻金矿床是青海省巴颜喀拉造山带北缘Au-Sb成矿带上新发现的中型金矿床，由于受“生态保护第一，尊重群众意愿”政策影响，勘查工作主要以深部勘查为主，本文选择该矿床有代表性的VI号矿体，研究其构造原生晕轴向分带序列。研究结果表明：VI号矿体原生晕分带序列为：(Au、Sb、As)→(Bi、Pb)→(Ag、Cu、Zn)；分带序列呈现“反分带”趋势，地球化学参数“反转”，前、尾晕共存，预测VI号矿体深部延伸较好或有隐伏矿体存在的可能性，圈定了成矿靶区，以期为矿山下一步探矿工作提供科学依据。

The Dongchenggongma gold deposit is a medium sized gold deposit found in North Qinghai province with Au-Sb mineralization of Bayan Har orogenic belt, due to the"ecological protection first, respect for the wishes of the masses"policy implications, exploration work mainly in the deep exploration, The paper has selected the representative No. VI orebody of this desposit to study the axial zonality sequence of tectonic primary halos. The results have shown that the axial zonality sequence of tectonic primary halos of No.VI orebody can be concluded as fol owing sequence:(Au、Sb、As)→(Bi、Pb)→(Ag、Cu、Zn);zoning sequence is"anti zoning"trend, geochemical parameters"reversal", front, rear halo coexistence, the probability of better spread of No. VI orebody and the existence of concealed orebodies, delineation of the ore target area, and to provide the scientific basis for the next step prospecting work of mine.
