摘要
区域变质作用、韧性剪切作用和超高压变质作用为SiO2富集创造条件,印支期-燕山期的构造活动为石英脉富集定位创造构造环境。东海群地层、韧性剪切带、超高压变质带为石英脉的形成提供了SiO2物质来源。
The regional metamorphism,ductile shear and ultra-high P metamorphism provide the conditions for SiO2 enrichment.The Indosinian-Yanshanian structural movement provides the structural environment for the enrichment and location of quartz vein.And the Donghai Group strata,ductile shear and ultra-high P metamorphic zone provide the material source for the formation of quartz vein.
