| 摘 要： | 在详尽分析西峡桑评红柱石矿床区域成矿地质背景及矿床基本地质特征的基础上，研究了成矿物质的来源；并以成因矿物学的理论为准则，用石榴石一黑云母矿物对及主要共生矿物的氧同位素地质温度计，得出该矿床的成矿温度主体为550～625C，相应的压力为380～420MPa，温度梯度为39．1C／km；进而分析了成矿的微量元素地球化学特征及稀土元素地球化学特征。最后，概括出了该矿床的成矿模式。

| Abstract: | On the base of detailed analysis of the regional metallogenic geological background and geolog-ical characteristics of Sangping andalusite,the source of the metallogenic mass was studied. The metallogenictemperature of this deposit is 55O~ 625 C,the corresponding pressure is 38O~42O MPa and the temperaturegradient is 39. 1 C /km,on the basis of minerageny theory,by use of oxygen-isotope geothermometer of ga-met-biotite mineral couple and main associated mineral. And then the metallogenic microelement and rareearth element geochemistry was analysised. Finally the metallogenic model of this deposit was generalized. |
