辽北法库一带硅灰石矿床控矿因素分析

Analysis on Metallogenic Factors of the Wollastonite Deposit Around Faku in the Northern of Liaoning Province

简述辽宁省北部法库—调兵山一带硅灰石矿成矿地质特征及成矿带分布情况。总结出该地区硅灰石矿控矿因素主要有三个方面:一是分布有一定规模的硅灰石方解石大理岩或硅质方解石大理岩;二是中酸性岩浆岩广泛发育;三是大理岩中或接触带硅灰石化为主,矽卡岩化相对较轻。指明该地区硅灰石矿床类型属接触(热)变质型矿床。

Sketch the metallogenic geologigcal character and metallogenic belt distribution ofwollastonite deposit around Faku- Diaobingshan in the northern of Liaoning province. Summarized three metallogenic factors for wollastonite deposit in the region： First, there are a certain amount of wollastonite calcite marble or siliceous calcite marble; Second, intermediate-acidic magmatic rocks are widely developed; Third, there is condition that turns into wollastonite in the marble and contact zone, skarnization is relatively weak. Indicate the type ofwollastonite deposit belongs to contact metamorphic types in the region.
