湖南湘东钨矿床地质特征及找矿方向
|
摘要
湘东钨矿为典型的石英脉型黑钨矿床,其资源量已经面临枯竭。通过对湘东钨矿地层、构造、岩浆岩的详细阐述,分析对比矿区南组脉与北组脉地质特征,讨论了岩浆岩成矿之间的关系,认为矿体与燕山早期花岗岩侵入有关;而通过对构造的观察与大地构造背景分析,认为矿区老山坳断层表现为先逆后正的性质,矿脉富集于该断层所派生的R与R’裂隙之中。最终,通过所建立的构造演化图,认为老山坳断层下盘深部与控盆断层深部具有一定的找矿前景。
The Xiangdong W deposit in Hunan belongs to typical quartz vein type one,its resources are exhausted.This article deals with stratigraphy,structure and magmatic rock,geological features of southern and northern veins,relationship between magmatic rock and mineralization of the Xiangdong W deposit.From those it is concluded that W mineralization enrichment is related to the early Yanshanian granite intrusion and the R and R' fissures induced from the Laoshan'ao fault.There are prospecting potentials in the deep of the footfall of the Laoshan'ao fault and basin-control fault.
