摘  要:针对辽西地区沸石矿产资源矿点较多,勘查及研究程度较低,不具规模性商业开发的现状,通过对辽西地区沸石矿床成因的研究,得出辽西地区沸石矿产的赋存严格受控于中生代火山喷发—沉积旋回中的中酸性火山岩,侏罗—白垩系的土城子组、髫髻山组和义县组的中酸性熔岩—碎屑岩段是矿产赋存最有利的岩性段;辽西地区的沸石矿产的成因可划分为火山熔岩型、火山碎屑岩型、火山-沉积岩型、沉积型和构造型五种成因类型,其中,前四种类型储量大、品位高,具有良好的开发应用前景,是辽西地区沸石矿床的主要成因类型,而构造型因其矿床规模一般不大、且不稳定、质量不一、品位变化也大、工业价值较小,为次要的成因类型。该结果为辽西地区沸石矿产的勘探开发提供了一定的依据。For the western Liaoning zeolite, bentonite, perlite three kinds of mineral resources, mining points more, the current low level of exploration and research, non-scale commercial development of the status quo, carried out in western Liaoning zeolite, bentonite, perlite deposits of the three kinds of geological features and genesis of the study. Emerging from the study: western Liaoning zeolite, bentonite, perlite mineral resources of the occurrence of three strictly controlled by Mesozoic volcanic - sedimentary cycles in the intermediate-acid volcanic rocks, Jurassic - Cretaceous Tuehengzi, Tiaojishan and the Yixian Formation of intermediate-acid lava - elastic section is three kinds of mineral occurrence most favorable lithologic; western Liaoning zeolite, bentonite, perlite can be divided into three kinds of minerals, the causes of volcanic lava type, pyroclastic rock type, volcanic - sedimentary rock type, sediment type and structure type are five genetic types. Furthermore, for the western Liaoning zeolite, bentonite, perlite three kinds of mineral exploration and development to provide a certain basis.
