目前已知伴生铀矿化的交代变质岩有五种独立的建造类型:中温钠质交代岩和四种低温建造变质岩——钠质交代岩、钾质交代岩、黄铁细晶岩和热液泥质板岩。 作者在研究一个古生代褶皱区的热液铀矿床时,查明了近矿交代岩。按其矿物-地球化学特征,它们不同于上述的交代岩建造。仔细研究这些生成物可以判断;其中广泛发育有水云母化现象。此种情况,以
At present, there are five independent types of metamorphic rocks associated with uranium mineralization: moderate-temperature sodium-bearing metamorphic rocks and four low-temperature-building metamorphic rocks-sodium metasomatism, potassic metamorphic rocks, pyroxene and hydrothermal mud Quality slate. When studying a hydrothermal uranium deposit in an Paleozoic fold zone, the authors identified near-ore metasomatism. According to their mineral-geochemical characteristics, they are different from the above-mentioned metasomatism. Careful study of these products can be judged; among them, micritism is widely developed. This situation, with
