| 摘 要： | 浙江平水铜矿(原名西裘铜矿)是20世纪70年代初期探明的中大型块状硫化物矿床,位于扬子板块和华夏板块结合带(即钦杭结合带)北东段的典型的块状硫化物矿床。本文系统研究了平水铜矿与条带状矿石伴生石英中的流体包裹体,发现流体包裹体类型比较简单,主要是富液相的气液两相包裹体,分为2类:一类IIa原生的流体包裹体,其均一温度从192~245℃(平均217℃),盐度从2.75%~5.7% NaCleqv,另一类IIb次生的流体包裹体,其均一温度从158~189℃(平均173℃),盐度从2.75%~4.6% NaCleqv拉曼测试也表明流体包裹体的气相成分基本为水蒸气,未鉴定出其它气体成分。这种流体包裹体数据符合典型的火山成因块状硫化物矿床的流体特征,进一步证实了平水铜矿的成因类型和成矿模式。这一认识对深入了解平水铜矿的成因、形成和演化具有重要地质意义。 |

| Abstract: | The Pingshui copper deposit found in the 70's is the biggest copper deposit in Zhejiang Province,and is a typical massive sulfide deposit in the northeast part of Qinzhou-Hangzhou collision belt between Yangtze and Cathaysia blocks.However,up to now the researches about ore-forming fluid,especially fluid inclusions on it are still lacked.This study made a systematic research works on fluid inclusions in Pingshui copper deposit.The type of fluid inclusions is very sample,mainly the liquid(H2O)-rich inclusion... |
