| 摘 要： | 中畈金矿体产于青白口系邓家组中的碎裂岩蚀变带及其旁侧次级构造控制的砂岩蚀变带和脉岩中,受北西西向构造控制明显。近年来受业主委托,笔者组织了该区首选地段的工程施工,目前通过工程控制共圈定金矿体9个,其中Ⅰ-1、Ⅱ、Ⅷ-1、Ⅷ-2号矿体为该区主要矿体。工作中笔者采取了大量分析测试样品,进行了细致的实内分析研究,同时结合野外工作实际,系统总结了中畈金的矿石类型、矿石矿物成分、金的分布、赋存状态等特征,并对金的富集规律做了初步研究,以期对该区乃至该区域找矿起到借鉴作用。

| Abstract: | The Zhongfan gold ore body occurs in the altered zone of cataclasite of the Dengjia Formation of the Qingbaikou System,and the nearby secondary structure-controlled altered zone of sandstone and vein rock,is evidently controlled by NWW structures.In recent years,commissioned by the property owner,we organized engineering work in the priority section of the area,and outlined 9 gold ore bodies,Ⅰ-1,Ⅱ,Ⅷ-1 and Ⅷ-2 of which are major ones.Based on careful analysis and study of a great number of samples collected,combined with field work and observations,this paper summarized the ore type,mineralogical composition,distribution and state of occurrence of gold,and obtained initial knowledge of the gold enrichment,which may be helpful to regional ore prospecting. |
