中文摘要：

球粒状铁绿纤石（？）产出于云南昭通玄武岩晶洞中，与其共生的矿物有绿帘石、硅铁灰石、水晶、葡萄石及方解石等矿物。扫描电镜（SEM）下，该矿物呈扁平长柱状，沿柱体方向呈不同程度的弯曲，并绕球粒中的包裹体聚合生长成不同形状的球粒，聚合生长的方式取决于包裹体在球体中的位置与距离，越近球粒表面，越趋于平行排列。水晶的流体包裹体测温及拉曼光谱分析表明，铁绿纤石（？）属低温（148～169％）热液产物，热液的盐度为11％-12％，富含H2O2及微量CH4，铁绿纤石（？）的形成可能与有机质（CH4）有关。

英文摘要：

The pelletal grained pumpellyite （ Fe^2＋） （ ？ ） occurs in basaltic druses of Zhaotong area, Yunnan Province. The associated minerals include epidote, babingtonite, quartz, prehnite, calcite etc. Scanning electron microscopy reveals that pumpellyite （ Fe^2＋） （ ？ ） is tabular and somewhat bended in the direction of cylinder and forms grains around the inclusions. The growth modes depend on the position of inclusions in grains, and the nearer it is to the surface of grains, the more parallel its arrangement. The fluid inclusion thermography and Raman spectra of quartz indicate that pumpellyite（ Fe^2＋） （ ？ ） is a product of low temperature hydrothermal activity（ 148-169℃ ）, with the salinity being 11% -12% and the ore-forming fluids enriched in n20 and minor CH4. In addi- tion, the formation of pumpellyite（ Fe^2＋） （ ？ ） grains is possibly related to Organic material（ CH4 ）.
