摘要
中国南方晚石炭世海域广大,普遍发育了一套台地相碳酸盐岩,黔南是其中的一个代表性地区。工作区晚石炭世地层发育较典型的生物泥丘,是开展生物灰泥丘研究的良好场所。本文对生物礁发育的地层开展了生物地层学研究工作,详细分析了产礁地层中蜓等生物群特征,通过对比研究,确定本区生物灰泥丘的产出层位为上石炭统上部地层,即马平组下部地层。通过与世界Waulsortian丘进行对比研究发现,黔南地区所发育的灰泥丘与Waulsortian丘具有明显的差异,因此确定黔南地区所发育的灰泥丘并非Waulsortian相,是石炭纪特殊的灰泥构造。
The sea area of south China in late carboniferous is large, it develops a series of platform facies carbonate, the south Guizhou province is one of the typically area. The carbonate platform with low water in this area is feasible for life surviving, especially for the benthos blooming,and the biological lithogenesis is very intensity. Our workaround that the stratum of late carboniferous is including kinds of mud mound, and it is the ideally area to research the mud mound of late carboniferours of south China. Through the comparative study with Waulsortian, founding that the mud mounds which develop in southern Guizhou provience are more difference with Waulsortian, so as to identify that the mud mounds are not Waulsortian like.
