| 摘 要： | 晚石炭世—早二叠世早期黔南地区发育一套巨厚层碳酸盐岩沉积,具有分布面积广、地层发育完整、剖面连续性好、沉积环境多样、岩性组合丰富等特点,是研究碳酸盐岩沉积特征及层序地层的理想场所。本文以黔南独山地区甲刀寨剖面为基干,以数条相邻剖面为辅助。运用沉积学及露头层序地层学的有关理论和研究方法对黔南地区露头实测资料进行沉积特征分析、层序划分及对比,认为黔南地区晚石炭世—早二叠世早期主要为碳酸盐局限台地、开阔台地、台地边缘-斜坡、台盆相沉积,而独山地区仅发育局限台地、开阔台地相沉积,整体表现为北北东"台"、南南西"盆"的格局。层序充填特征表现为:早期层序充填主要受控于三级海平面变化;晚期构造运动相对加强,构造活动和三级海平面变化共同控制层序格架内的沉积充填,表现在台地内沉积的填平补齐。 |
