epithermal gold deposit meaning in English
浅成低温热液金矿床
Examples
- The characteristics , distribution and prospect of epithermal gold deposits
分布和找矿前景 - The geochemical characteristics and ore - forming model of the epithermal gold deposit in west tianshan mountains
西天山地区浅成低温热液型金矿地质特征及成矿模式 - The axi gold deposit ; laumontitization ; epithermal gold deposit ; geothermal fluid minerogenetic system ; west tianshan
阿希金矿浊沸石化浅成低温热液型金矿地热流体成矿系统西天山 - The ore - forming material is mostly from volcanic rock , and sub volcanic rock provides the main thermal and some mineral materials . the ore - forming fluid is from meteoric water . as a result , it should be a kind of adularia - sericite type of epithermal gold deposit
成矿物质主要来自矿区火山岩围岩，次火山岩提供了主要热源和部分矿源，成矿流体来自大气降水，矿床成因类型为低硫化物冰长石?绢云母型浅成低温热液型金矿。 - Through field investigation , microscopic study , x - ray phase analysis and mineral infrared spectrum analysis , the authors determine the laumontitization had occurred widely in the axi gold field . according to the development of laumontitization and its relationship to mineralization , authors reveal that the laumontitization appeared mainly at the top and periphery to ore - bodies . it befallen at the edge of the geothermal fluid system or happened in the late stage of geothermal fluid system evolution , hence can be assigned as an indicator to prospect for epithermal gold deposit . the fluid causing laumontitization in the axi gold deposit is similar to those causing hot spring type gold deposit or in modern geothermal field . the fluidization of the axi gold deposit happened in carboniferous , showing the west tianshan is a good district for epithermal gold mineralization and preservation . so west tianshan is prospecting for exploring epithermal gold deposit
通过野外考察显微镜下薄片鉴定x射线物相分析和矿物红外光谱等研究，确定了阿希金矿浊沸石化的普遍存在根据浊沸石化发生的规律及其与矿床形成的关系，确定浊沸石化主要见于矿体的上部和外围，发育在地热流体系统的边缘和演化晚期，可作为寻找浅成低温热液型金矿的标志之一。导致阿希金矿浊沸石化的流体性质与热泉型金矿成矿流体和现代地热田类似，流体作用发生在石炭纪，证明西天山地区具有良好的浅成低温热液型金矿的形成和保存环境，因此找矿前景较好。
