| 摘 要： | 八方山多金属矿床产于中泥盆统星红铺组、古道岭组。指示元素有Ｃｕ、Ｐｂ、Ｚｎ、Ａｇ、Ｃｄ、Ｈｇ、Ａｓ、Ｓｂ、Ａｕ、Ｂａ、Ｓｒ、Ｂ等，原生异常的轴向分带序列（从上到下）：Ｚｎ－Ｈｇ－Ｐｂ－Ａｇ－Ｃｕ１－Ｂａ－Ｓｒ－Ｓｂ－Ａｓ－Ｃｕ２、Ｎｉ、Ｃｏ、Ａｕ，具有明显多建造晕的特点。八方山多金属矿床是由海底喷流（汽）同生沉积－叠加、再造作用形成的。

| Abstract: | The Bafangshan polymetallic deposit in Shaanxi is hosted in the Xinghongpu Formation and Gudaoling Formation of Devonian.Its indicator elements are Cu,Pb,Zn,Ag,Cd,Hg,As,Sb,Au,Ba,Sr and B.The sequence of axial zoning or vertical zoning(from top to bottom) is Zn-Hg-Pb-Ag-Cu 1-Ba-Sr-Sb-As-Cu 2, Ni,Co,Au.The deposit with multiple formation of haloes could be formed by exhalation at sea bed, synsedimentation and superimposed mineralization. |

| Keywords: | polymetallic deposit sequence of element zoning exhalation ore forming and halo forming pattern |
