摘要
江西武宁田丘地区脉石英矿赋存于新元古界双桥山群安乐林组及燕山早期侵入岩岩体之间。矿体产出受构造控制,石英脉整体走向北东,与区内断裂构造方向大致相同,沿走向延伸约760m,厚度8.15~41.56m。脉石英矿石主要为中低温石英,矿物成分较单一,SiO2含量高,矿石内包裹体以气液包裹体为主。矿床类型为岩浆期后热液型。通过总结脉石英的矿床地质特征、矿体特征以及矿石质量,分析矿床成因以及控矿因素,旨在为该区域寻找同类或类似的脉石英矿提供帮助和借鉴。
The mineral composition of the vein quartz ore in the Tianqiu area of Wuning,Jiangxi is relatively single,with high SiO2 content.The ore body mainly occurs between the Anlelin formation of the Shuangqiaoshan group in the Neoproterozoic and the early Yanshan intrusive rock mass.The occurrence of the ore body is controlled by the structure,and the overall direction of the quartz vein is northeast,roughly the same as the direction of the fault structure in the area.It extends along the strike for about 760m,with a thickness of 8.15~41.56m.Vein quartz ore is mainly composed of medium to low temperature quartz,and the inclusions in the ore are mainly gas-liquid inclusions.The deposit type is post magmatic hydrothermal type.This paper summarizes the geological characteristics,ore body characteristics and ore quality of vein quartz,analyzes the origin of ore genesis and ore control factors,and aims to provide help and reference for the exploration of similar vein quartz deposits in this region.
