| 摘 要： | 本文作者通过对钟祥累托石粘土岩大量、系统的岩石薄片鉴定及岩石类型的研究,发现其富变余火山玻屑及火山灰球,结合宏观地质特征的研究,得出其矿床成因归属火山—沉积矿床大类中的沉火山碎屑矿床亚类的结论。这对于远火山喷发区、岩浆岩分布不广、属于正常沉积矿区的地质找矿具有现实意义。

| Abstract: | Rectorite clay ore in Zhongxiang is located 40 km west to Zhongxiang town of Zhongxiang county, Hubei and is the first industrial rectorite deposit of large scale in China. By identifying bulk and systematic thin sections of rectorite clay rocks and studying the rock types, the auther discovers that the rectorite deposit is rich in blastopyro-vitric fragment and volcanic ash balls. By the study of macroscopic geology characteristics, the auther reaches the conclusion that the genesis of ore deposit belongs to the subtype of sedimentary-volcanic clastic deposit from the volcanic-sedimentary type of ore deposit. This conclusion is of practical significance for geological prospecting in the areas of televolcanic eruption lacking in magmatite but belonging to normal sedimentary rocks. |
