hydrothermal alteration meaning in Chinese
热液蚀变
水热蚀变
Examples
- Petrological and mineralogical examinations of core material can be used to identify hydrothermal alterations .
岩芯的岩石学和矿物学研究也能用来鉴定水热蚀变。 - Hydrothermal alteration is closely associated with gold mineralization , but different types play different roles in gold mineralization
热液蚀变与金矿化关系密切，但不同的蚀变对金矿化作用不同。 - Potash micatization is one of the main hydrothermal alteration minerals genetically related to the lead - zinc - silver deposit . it usually shows as muscovitization , sericitization and illitization . this paper presents a comprehensive study on the chemical composition of potash mica , adapted the follow methods : electronic probe , differential thermal analysis , x - ray diffraction analysis . at last , the structu ral characteristics and the geological environment of potash mica forming have been discussed
系统地研究了钾质白云母化的矿物组成，采用了电子探针差热分析x射线分析等技术方法，探讨了钾质白云母的结构特征和形成的地质环境及找矿意义。 - The main achievements obtained in this paper are as follows : 1 . some of new recognitions were obtained on such aspects as strata sequence , rock type , metamorphism , hydrothermal alteration and the sedimentary environment by the study on many profiles in this area , with discovery of volcanic rocks for the first time in ore - bearing strata and ore bodies
取的了如下主要成果和认识： 1 、通过对矿区地层多条剖面的研究，对地层的层序、岩石类型、变质作用、热液蚀变及原岩沉积环境有了新的认识，特别是在赋矿地层及矿体中首次发现了火山岩。 - The hydrothermal activities which were complicated and acted a positive effect in the formation of the zhulazaga gold deposit resulted in hydrothermal alterations of multiepisode , including pyroxeneization , actinolitization , epidotization , ice - feldsparization , silicification , chloritization and carbonatization etc . the research on inclusions in quartz of the ore indicates that the hydrothermal fluid varying greatly in temperature with an average of 286 shows characteristics of high temperature
3 、朱拉扎嘎金矿的形成中热液活动起到了积极的作用，热液活动不仅复杂而且具多期性，有透辉石化、阳起石化、绿帘石化、绿泥石化、硅化、冰长石化、碳酸盐化等。矿石中石英包裹体的研究表明，含矿热液的温度变化范围较宽广，平均在286 ，显示中偏高温特征。
