川西木绒隐伏伟晶岩型锂辉石矿床综合找矿模型的建立及在容须卡的应用示范
Establishment of an integrated exploration model for hidden pegmatite-type spodumene deposits in Murong,western Sichuan and their application in Rongxuka
摘要
Abstract
As the target of mineral exploration shifts from shallow and easily identifiable deposits to deep and concealed,difficult-to-recognize ores,the integrated application of various exploration techniques is key to achieving breakthroughs in mineral discovery.This paper,through the use of geological and integrated geophysical and geochemical data and techniques,reports the largest single lithium deposit in Asia—the Murong super-large pegmatite-type lithium deposit—which was recently discovered on the western side of the Jiajika area in the Ganzi-Litang belt of western Sichuan.Based on data obtained from the Murong mining area,an integrated exploration model for hidden rare metal pegmatite deposits in the western Sichuan region was established,which includes metamorphic mineral mapping,structural analysis,a geoelectrical chemical survey,and an audio frequency magnetotelluric(AMT)survey.With this integrated exploration model,we first delineated the strip-shaped andalusite belt through metamorphic facies mapping methods.Through structural research,the andalusite belt was found to be coupled with the schistosity zone and the bedding shear zone,which provide a space for the accumulation of rare metals.Then,based on geochemical anomalies dominated by Li,Rb,and Cs delineated by the geoelectrical chemical survey,the spatial positions of deep anomalies were located via the AMT survey,where effective validation was conducted for the deep part of Murong.The combination of exploration techniques successfully applied in this study highlight their potential for identifying hidden pegmatite-type spodumene deposits in Rongxuka,and provides a reference for the exploration of similar ore deposits in the future prospecting activities.关键词
