摘要
位于黔南贵州惠水县摆金村剖面,露头发育良好,层序较完整,作为分析黔中隆起及周缘石炭系层序地层及沉积相的典型剖面.识别出了7个层序界面,从而将该剖面划分为6个完整的三级层序.CSQ1沉积相为三角洲相,而CSQ2到CSQ3沉积相就从浅海陆棚逐渐向台地相过渡,CSQ5、CSQ6又由局限台地相到开阔台地相过渡,反映出海平面由浅变深的过程.总结出惠水地区石炭系沉积模式为三角洲-碳酸盐台地混合模式.
The section in Baijin Village of Huishui County, Guizhou, shows several good outcrops, the sequence is com- plete, and as a typical profile in analyzing the sequence stratigraphy and sedimentary facies of Carboniferous in Central Guizhou Uplift and its adjacent areas. Seven sequence boundaries have been identified, and the section is divided into 6 three- grade sequences. CSQ1 sedimentary facies is Delta facies, CSQ2 to CSQ3, the sedimentary facies started transiting from shallow shelf gradually to the platform facies, and CSQS, CSQ6 transited from restricted platform facies to open plat- form facies, reflecting the process of sea level change from shallow to deep. It can be concluded that the sedimentary model of the Carboniferous System in Huishui area is the mixed mode of delta carbonate platform.
