| 中文摘要: |
| 石灰窑稀有金属矿位于内蒙古锡林浩特市境内,与“八〇一”稀有金属矿床同产出于天山—内蒙—兴安地槽多金属成矿区沙不楞山稀有金属及多金属成矿带内,成因均为燕山期碱性花岗岩晚期岩浆热液在封闭环境中形成的分异交代型矿床。石灰窑矿床是以铌(Nb)、钽(Ta)伴生铷(Rb)为主的稀有金属的矿床。含矿岩体为燕山期碱性花岗岩,岩体普遍矿化。文章通过对该含矿岩体的地质特征、岩石地球化学及矿体特征的分析研究,总结其成矿规律,探讨其成因类型。 |
| 英文摘要: |
| The Shihuiyao rare metal deposit located in Xilinhaote region, Inner Mongolia is distributed in the Shabuleng rare metal and polymetallic metallogenic belt within the Tianshan Mountain-Inner Mongolia-Xingan geosyncline polymetallic metallogenic district as the No. 801 rare metal deposit. The deposit belongs to the differential metasomatism deposit by the late magmatic hydrothermal fluid derived from the Yanshanian alkaline granite in a enclosed environment. The Shihuiyao rare metal deposit dominates with niobium (Nb)and tantalum (Ta)and associated rubidium (Rb).The ore-bearing host rock is the Yanshanian alkaline granite which is widely mineralized. Based on the analysis and research of geology and geochemistry of the ore-bearing host rock, and characteristics of the orebody, the authors summarize the metallogenic regularities and discuss the genesis of the Shihuiyao rare metal deposit. |
