摘要: 贵州普安铅厂泥盆纪主要发育中晚泥盆世的地层。区内出露有硅质岩、碎屑岩和碳酸盐岩,以碳酸盐沉积占主导地位。地层总厚1056米,由碳酸盐角砾岩、泥灰岩、灰泥岩、砂屑生物屑泥粒岩和粒泥岩、礁灰岩、含石英粉砂质泥岩、硅质泥岩和硅质岩等组成,碳酸盐岩共占83%左右。剖面上微体生物竹节石类发育,硅质放射虫和硅质海绵骨针依稀可见。区内各地重力流沉积屡见不鲜,计有碎屑流沉积、高密度浊流沉积和少量颗粒流沉积。罐二段发育深水丘状生物礁。 铅厂中晚泥盆世以深水沉积为主,包括盆地相、盆地边缘相和下斜坡环境。

Abstract: In Puan-Qianchang of Guizhou Province, the middle and late Devonian sedimentary rocks were mainly developed during the Devonian Period.In this region principally cropped out carbonate rocks, a few silieilith and terrigenous clastic sediments.All sediments, which consist of carbonate breccias, argillaceous limestones, mudstones, wackstones, packstones, reef rocks, argillites and silicilithes are about 1,056 meters thick, and are about 83% of carbonate rock.
