辽西地区珍珠岩矿床成因及成矿模式探讨

珍珠岩为一种酸性火山玻璃熔岩,配用不同胶结剂可制成多种珍珠岩制品,具有重量轻、耐腐蚀、隔音好、不燃烧等性能,广泛应用于建筑、化工及国防等领域。辽西地区珍珠岩是辽宁乃至全国重要产地之一,因此研究该地区珍珠岩矿床成因及成矿模式,具有重要的现实意义。在充分收集该地区珍珠岩矿床地质特征基础上,结合前人的研究成果,总结了矿床的时空分布规律,分析了矿床成因,构建了成矿模式。结果表明,辽西地区具有较好的珍珠岩成矿环境条件,需进一步开展矿产资源评价工作。

Discussion on genesis and metallogenic model of perlite deposits in western Liaoning

As an acid volcanic glass lava, perlite can be made into a variety of perlite products with different cementing agents. These products have the properties of light weight, corrosion resistance, good sound insulation and non-combustion, and are also widely used in construction, chemical and defense and other fields. Western Liaoning is one of the important perlite-producing areas in Liaoning and even in China, so the study on genesis and metallogenic model of perlite deposits in this region is of significant practical importance. On the basis of fully understanding the geological characteristics of perlite deposits in this area, and Ombined with previous research results, the authors summarized the temporal and spatial distribution of ore deposits, analyzed the genesis of ore deposits and constructed the metallogenic model. The research results show that western Liaoning has good environmental conditions of perlite mineralization, and further mineral resources evaluation work need to be carried out.
