摘要
本文根据近几年来柳州市1:5万区调工作中所获得石炭系较多的地层古生物新资料,对柳州市石炭系划分进行探讨。文中较详细论述了泥盆系与石炭系界线、下石炭统内部界线、上下石炭统界线和石炭系与二叠系界线划分的新证据和认识。指出位于柳州市东郊马鹿山剖面产出较丰富的(?)类、珊瑚、牙形刺化石,为当前广西碳酸盐台地相区发育良好的石炭—二叠系界线剖面之一。
Based on much information about the stratigraphy and the paleontology of the Carboniferous system from 1 : 50000 scale regional geological reconnaissance in Liuzhou in recent years. The article has discussed the classification of Carboniferous system there. The new evidence and realization of boundaries between the Devonian and the Carboniferous systems, the Upper and Lower Carboniferous series, the Carboniferous and Permian systems, and the boundary within the Lower Carboniferous series have been detaitedly expounded. Ma Lushan section located in the eastern suburb of Liuzhou rich in foraminiferas, corals, conodonts is one of the best Carboniferous-Permian boundary sec-ions in carboniferous platform in Guangxi.
