绿帘石族矿物不同元素置换对其晶体结构的影响
Influence of Different Elemental Substitutions in Epidote on Its Crystal Structure
摘要
Abstract
Epidote group minerals are common hydrous nesosilicate.The unique crystal structure of epidote al-lows them to be significantly enriched in various trace elements,especially divalent large ionic lithophilic ele-ments(Sr and Pb),rare earth elements(REE),and transition group metallic elements(TME).Under certain temperature and pressure conditions,these ions will be substituted with Ca,Fe,and Al ions in cordite in a homogeneous manner.This paper summarizes the microstructural changes brought about by the substitution of elements such as Fe,Mn,Sr,Pb,Cr,V,and REE in the crystals of epidote,and aid in understandingthe im-portant applications of such microstructural properties in tracing the fluid source region,in indicating the chan-ges in fluid composition and processes,and in geochronology.关键词
