摘要

对新疆阿舍勒铜矿中的石英进行了二维、三维热释光和光释光的分析

对该铜矿附近的凝灰岩、玛尔卡库里大断裂中的石英脉、金矿和花岗伟晶岩中的石英矿物进行了热释光、光释光的分析与对比。铜矿体中的石英的释光特征与凝灰岩、断裂带石英脉、金矿、花岗伟晶岩中石英存在较大差异。铜矿中石英在170℃有2个发光峰

波长段分别为340nm和405nm左右

而没有如金矿和断裂带石英中存在的与热液成因相关的560—590nm附近的发光峰

也没有如花岗伟晶岩石英中存在的与深成岩浆作用有关的476nm和625nm附近的2个发光峰。结合对样品的稀土元素进行的中子活化分析

证明铜矿的形成与金的流体成矿不同

属于火山成因铜矿床。

Abstract

Characters of 2D TL

3D TL and OSL of quartz occurring in Ashele copper deposit

Xinjiang were ana- lyzed.The contrast experiments of TL and OSL of quartz occurring in tuff

Markakuli fault zone

gold deposits and granite pegmatite close to Ashele copper deposit were also conducted.Notable difference was found in TL and OSL of the quartz samples.The 3D TL of quartz samples from Ashele copper deposit have just two TL peaks at 340nm and 405nm at 170℃.However

there was a TL peak at 560—590nm

which is related to hydrothermal genesis

in quartz samples from the gold deposit and fault zone

and there were TL peaks at 476nm and 625nm

which are related to hypogene magmatism

in quartz samples from the granite pegmatite.The luminescence characters of quartz com- bining with the REE analyses suggested that the ore genesis of Ashele copper deposit is different from hydrothermal genetic gold deposit and Ashele copper deposit is an volcanogenic deposit.
