摘要
龙山金锑矿床位于湘中金锑成矿带中部,地处白马山—龙山—紫云山EW向穹隆状隆起区东部。尽管近年来区内找矿取得了一些新进展,但深部找矿尚未有重大突破。在系统总结区域成矿地质背景、矿区和矿床地质特征的基础上,对矿区成矿构造型式、构造控矿规律和构造演化序列进行了讨论。研究表明:区域上矿床分布受正向构造控制;矿区成矿构造型式为"米"字型;成矿具有明显的NWW、NNE 2组优势方位;矿体在走向和倾向上均表现出贫矿段与富矿段相间出现的规律。根据上述分析,对矿区深部进行了成矿预测,认为该区重点找矿区域为:1~#脉组101~#~105~#勘探线,垂向标高为-440^-610 m;2~#矿脉210~#~214~#勘探线,垂向标高为200~50 m,该类区域为矿区下一步找矿靶区。
Longshan Au-Sb Deposit is located in the middle of Au-Sb metallogenic belt in central Hunan Province,the east of Baimashan-Longshan-Ziyunshan east-west fornix shaped uplift area.Although some new prospecting progress has been acquired in the mining area,deep prospecting breakthrough has not be achieved.Based on systematic summary of the regional metallogenic geological background,geological characteristics of the mining area and deposit,the metallogenic tectonic pat- tern,tectonic ore-controlling regularity and tectonic evolution sequences of the mining area are analyzed and summarized.The study results show that:in general,the distribution of deposit is controlled by forward structures ;the metallogenic structural pat- tern is characterized double cross pattern;the obvious dominant metallogenic orientations of the mining area is NWW and NE ; the orebodies show the distribution characteristics of intersecting between poor ore section and rich ore section in the strike and the tendency.Based on the above discussion results,the deep metallogenie prognosis is carried out.It is indicated that the key prospecting area in this mining area is the No.1ore vein group,which is located in 101#-105#exploration lines and its vertical elevations is from -440m to -610m;the No.2ore vein,which is located in 210#~214#exploration lines,and its vertical eleva- tion is from 200m to 50re.The above areas can be taken as the prospecting target areas for further prospecting work of the min- ing area.
