摘要
江西省钨矿矿点多,资源储量在全国排名第一。表现为分布集中、规模大、矿床类型多、成矿作用多样共(伴)生组分多、综合利用价值大等特点;矿石类型白钨矿和黑钨矿,以白钨矿居多,黑钨矿矿矿床类型以石英脉型、云英岩型为主,白钨矿矿床类型主要以矽卡岩型、似矽卡岩型为主。矿床空间分布表现为“三横”、“三纵”,成矿时间主要为燕山期。燕山期大陆活化造山时期地壳重熔造浆,钨元素伴随S型或I型组合花岗质侵入体而富集。通过不同围岩蚀变及热液交代,形成不同类型、不同规模的钨矿床。
More tungsten deposits in Jiangxi Province,Resource reserves ranked first in the country.Expressed as Distribution concentration,Large scale,More types of mineral deposits,Diversified mineralization,More components of Symbiosis(Associated),High comprehensive utilization value,The type of ore is scheelite and wolframite,Mostly scheelite,The types of black tungsten deposits are mainly quartz vein type and Yunying rock type,The types of scheelite deposits are mainly skarn type and similar skarn type.The spatial distribution of the deposit is expressed as“Three horizontal”and“Three vertical”,The ore-forming time is mainly Yanshan period.Crust remelting and pulping during the activation of the Yanshanian continental period,Tungsten element enriched with S-type or I-type Combine granitic intrusion and enrich,Through different wall rock alterations and Hydrothermal exchange,Form different types,Different scale tungsten deposits.
