一、前言湖南郴县柿竹园多金属矿床属网脉状云英岩-矽卡岩复合型钨锡铝铋矿床。矿床成矿作用十分复杂,是多次成矿作用的产物。矿体呈透镜状、似层状,形态规则,厚度稳定。矿床自上而下分为大理岩锡矿体(Ⅰ矿带)、矽卡岩钨铋矿体(Ⅱ矿带)、矽卡岩钨钼铋矿体(Ⅲ矿带),矿体之间呈渐变关系。矿体围岩为泥盆纪泥质灰岩。Ⅲ矿带是矽卡岩钨钼铋矿体,位于含矿矽卡岩体的最下部,与下伏花岗岩体顶面吻
I. Preface The Shizhuyuan polymetallic deposit in Chenxian County, Hunan Province is a network vein-hosted dolostone-skarn composite tungsten-tungsten-aluminum-bismuth deposit. The mineralization of the deposit is very complex and is the product of multiple mineralization. Ore body was lenticular, layered, morphology rules, the thickness of stability. The ore deposit is divided into marble ore body (Ⅰ ore belt), skarn tungsten-bismuth ore body (Ⅱ ore belt) and skarn tungsten-molybdenum-bismite ore body (Ⅲ ore belt) from top to bottom. Gradient relationship. Ore body rock is Devonian argillaceous limestone. Ⅲ ore belt is skarn tungsten molybdenum bismuth ore body, located in the ore-bearing skarn body at the bottom, and the underlying granite top kiss
