巴泉铀矿床花岗斑岩的钠交代作用十分强烈。通过对各采矿中段的观察,精选45米中段5号穿脉剖面为例,进行岩石学的详细研究二作。钠交代作用在巴泉铀矿床是一次独立的地质作用。它发生在花岗斑岩成岩后,铀矿化之前。钠交代作用在花岗斑(?)中,空间分布上是连续的,在强烈部位花岗斑岩可能化成合钠长石78%的交代钠长岩。
Baquan uranium deposit granite porphyry sodium metasomatism is very strong. Through the observation of the middle sections of the mining and the selection of No.5 threading pulse profile in the mid-45-meter section, we conducted a detailed study on lithology. Sodium metasomatism is an independent geologic feature in the Baquan uranium deposit. It occurs after granite porphyry diagenesis before uranium mineralization. In the granite plaque (?), The sodium metasomatism is contiguous in spatial distribution, and the granitic porphyry in the intense part may be converted into 78% metacrite albite.
