| 摘 要： | 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。

| Abstract: | Na-metasomatism is extremely intensive in the granite- porphyry in Ba Quan uranium deposit after inoestigation on many sections of the underground mining samples were under detail study collected from a representative section of NO.5 funnel in 45m depth. The process of Na-metasomatism in Ba Quan is an independent geolo- gical function which occurs after the formation of granite-porphyry. Before uranium mineralization,The space distribution of Na-metaso- matism in granite-porphyry is in continuance Granite-porphyry in the intensively albitizated part may evolve into metasomatic albitite containing 78 percen't of albite. |
