天然沸石是在各种地质作用和不同的物理化学条件下形成的,根据成因特征天然沸石可分为以下类型:风化型沉积变质型、后生型、变质型、热液型和岩浆期后型。目前在苏联仅有同沉积和火山沉积有关的沸石矿床才具有实际意义(见表1),特别是沉积积变质型。近年来发现某些热液型矿床也具有工业价值。
Natural zeolite is formed under various geological conditions and different physicochemical conditions. According to genetic characteristics, natural zeolite can be divided into the following types: weathering sedimentary metamorphism, epigenetic, metamorphic, hydrothermal and post-magmatic posterior. At present, only the zeolitic deposits related to sedimentation and volcanic deposits in the Soviet Union are of practical significance (see Table 1), especially the depositional metamorphism. In recent years, some hydrothermal deposits have also been found to have industrial value.
