| 摘 要： | 根据汉中地区硫铁矿成矿特征可将其划分为沉积成因和火山成因两大类型。火山成因的主要分布于勉县、略阳、宁强三角区，沉积型分布于扬子区和南秦岭区。板块多次俯冲、碰撞与深大断裂系在火山型硫铁矿成矿成岩中占有重要地位，沉积型硫铁矿的形成则与陆源物质、有机质和造海运动关系密切。

PYRITE DEPOSTS IN HANZHONG DISTRICT:A DISCUSSION OF ORE TYPE AND MODEL |
| |
| Abstract: | Abstract Two main genetic types. sedimentary and volcanic, were clhofied for the pyrite deposits in Hanzhong district in relation to their characteristic mineralizations. Mainly reding in a V-shaped area covering Mianxian, Lueyang and Ningqiang, the volcanic type resulted from repeated subduction and collision of plates compered with the sedimentary type which bed a close genetic link with the coincidence between terrigenous and organic material supplying and sea--making movement. |
