| 摘 要： | 月西硫铁矿床位于秦岭褶皱系南秦岭印支褶皱带内金鸡岭向斜西部。矿体赋存于上泥盆统冷水河组的变泥钙质石英粉砂岩和泥砂质微晶灰岩中，受层位及北西西向次级断裂的控制。矿体在地表氧化成褐铁矿，氧化深度浅。成矿物质可能来源于多源。成矿温度低，压力小，是在弱酸性的弱还原条件下进行的。初步认为，该矿床属沉积再造单一硫铁矿床。

| Abstract: | The Yuexi pyrite deposit is located in western section of Jinjiling syncline within InoSinian folding belt of southern Qinling Mt., which belongs to Qinling fold system. Orebodies occur in meta-argillaceous calcareous quartzose siltstone and argillaceous sandy micrite that is Lengshuihe Formation of Upper Devonian series, and the orebodies are controlled by strata and NWW trending subsidiary fracture. The orebodies in surface have been oxidized limonite and oxidize depth is shallow. Mineralization substances may be multiple source.The author considers that the deposit belongs to sedimentary-reconstruction simple pyrite one, according to mineralization temperature is lower and pressure small as well as mineralization in condition of weakness acid and reduction. |
