我国南方晚二叠世煤层含有大量木栓质体,长期以来为地质学者所关注。其中以浙江长广煤田最有特色。长广煤田的C煤层不仅富含木栓质体,而且夹有丰富海相动物碎屑灰岩和介壳灰岩的透镜体。因此,研究该煤田树皮煤煤层的成因和沉积环境,探讨这一特殊煤种的成煤植物以及木栓质体的富集原因与沉积环境的关系,这对了解我国煤层的聚积环境、特殊煤种的形成,是有重要意义的。
The late Permian coal seams in southern China contain a large amount of cork body, which has long been of concern to geologists. One of the most widely characterized coal fields in Zhejiang Chang. The coal seam C of Chang-Guang coalfield is not only rich in cork body, but also contains lens bodies rich in marine marine clastic limestone and shell-shaped limestone. Therefore, the coal bark of the coal bark coal genesis and sedimentary environment, to explore the coal-bearing plants of this special coal and cork apatite enrichment causes and sedimentary environment relationship, which understand the accumulation of coal seams in our environment, special The formation of coal is of great significance.
