球粒状緑帘石产出于四川雷波基性火山碎屑岩的晶洞或层间裂隙中,与其共生的有石英、赤铁矿等矿物。镜下研究表明,緑帘石至少有2个世代,第一世代緑帘石呈浅緑色的针状体,集合体为菊花状;第二世代緑帘石呈暗緑色的柱状或楔形,集合体为球粒状或椭球状。它们都由球核与球枝两部分组成,两者间有明显的接触界线,表明球核与球枝不是同时结晶的产物,而是有先后形成关系。EPMA分析表明緑帘石成分中普遍含有较高的SrO(0.51%~1.13%),与其共生的水晶晶体的流体包裹体测温及拉曼光谱分析表明,气液包裹体主要由H2O及微量CH4组成,,緑帘石属低温(164~177℃)与低盐度(7.31%~7.73%)的热液产物。緑帘石的球粒是在低温、过饱和度大、环境条件转变时快速结晶形成的。
Pelleted epidote produced in Sichuan Leibo base volcanic clastic rocks or intergranular cracks, with its symbiotic quartz, hematite and other minerals. Microscopic studies have shown that the epidote, at least two generations, the first generation of epididymal light green acicular body, the assembly is daisy-like; the second generation of epididymides dark green columnar or wedge-shaped, aggregates For the ball granular or ellipsoid. They are composed of two parts of the core and ball branches, there is a clear line of contact between the two, indicating that the core and ball branches are not the product of simultaneous crystallization, but have formed a relationship. EPMA analysis shows that the epidote generally contains high SrO (0.51% -1.13%). The temperature and Raman spectra of the fluid inclusions of the crystal associated with it show that the gas-liquid inclusions mainly consist of H2O and trace CH4 Epinephrine is a hydrothermal product of low temperature (164 ~ 177 ℃) and low salinity (7.31% ~ 7.73%). Ephedra pellets in the low temperature, high saturation, the rapid transformation of environmental conditions formed.
