贵州织金煤矿区龙潭组岩石特征及其意义
ROCK CHARACTERISTICS OF LONGTAN FORMATIONOF ZHIJIN COAL-MINE IN GUIZHOU AND ITS SIGNIFICANCE
【摘要】 织金矿区含煤地层为上二叠统龙潭组,含主要可采煤层。煤系地层以含玄武岩屑、 6海绿石为特征的类碎屑岩夹碳酸盐岩,水平、沙纹、波状层理发育,煤系中稳定的灰岩、硅铁5质灰岩标志层较多,有利于煤层的划分与对比,并产丰富的动植物化石及碎块。属海、陆交替环境下的标型海陆交互相沉积。
【Abstract】 Stratum containing coal of Longtan Formation in Zhijin mine zone include mainly 6 layers of coal that can be picked. In coal beds, five sorts of clasolite with the characteristics of basalt bits and glauconite mixed with carbonate, bedding development of horizon, sand-vein, wave-shape, and lots of key beds of steady (silicon-iron) limestone, favour division and comparison. Plentiful zoolite and phytolite and fragment occur also in the coal bed. This bed belongs to typomorphic paralic deposition under paralic circumstance.
