| 中文摘要: |
| 以吉林省杨金沟和黑龙江省翠宏山两个大型钨矿床为例,阐述了吉黑造山带钨矿床的地质特征和成因。研究表明,辽宁东南部钨矿床主要表现为黑钨矿矿化,吉林延边地区以独立白钨矿矿化为主,而黑龙江小兴安岭地区则为伴生型白钨矿矿化。吉黑造山带内的钨矿床均与不同时期花岗质侵入岩有关,成因上有接触交代型和热液石英脉型两种类型。古生代以来多期次构造岩浆活动、广泛分布的花岗质侵入体以及碳酸盐岩地层,为区内钨矿床,尤其是白钨矿矿床提供了良好的地质条件。近年来的理论研究和找矿工作表明,吉黑成矿带具有较好的钨成矿潜力与找矿远景。 |
| 英文摘要: |
| This paper studies the geological characteristics and genesis of tungsten deposits in Jilin-Heilongjiang orogenic belt with case histories of large Yangjingou deposit in Jilin province and Cuihongshan deposit in Heilongjiang province. There are mainly wolframite deposits in southeastern Liaoning province, mainly scheelite-only deposits in northeastern Jilin province, and associated scheelite deposits in Heilongjiang province. All tungsten mineralization in Jilin-Heilongjiang orogenic belt, including mainly skarn and lode hydrothermal types, are closely associated with granites formed in different periods. In Jilin-Heilongjiang metallogenic belt, multiple-period tectonic activities, extensively occurring granitic intrusions and carbonate strata provide favorable ore-forming geological condition for tungsten mineralization, especially for scheelite one. According to theoretical studies and exploration practice, we can draw a conclusion that the metallogenic perspective of tungsten deposits in Jilin-Heilongjiang metallogenic belt is worth further studying. |
