摘要
通过野外地质调查、岩相学、电子探针分析、地球化学分析等方法,初步查明修武地区东部上寒武统西阳山组白色-绿色石英脉白色部分除石英外基本无其它矿物,而绿色部分却可见少量的微颗粒碳酸盐矿物、粘土矿物以及黄铁矿、赤铁矿等金属矿物。稀土特征为轻重稀土分异较强,富集轻稀土,δEu无异常,δCe负异常。石英脉为两期低温热液形成。
Depending on the field geological survey, petrographic methods, element chemical analysis and EPMA, it is found that white quartz almost has no other minerals, while green quartz contains a small amount of micro-particles of carbonate minerals, clay minerals, pyrite, hematite and other metallic minerals in the white - green quartz veins from Xiyangshan group of upper cambrian in Xiuwu easter. It has a strong fractionation between LREE and HREE, and mainly enriched in light rare earth. 8 Eu is not abnormal,δ Ce is negative anomalies. In addition, quartz veins were caused by the two epithermal.
