摘要:

针对黔南-桂中凹陷泥盆系发育的台盆沉积体系,利用露头剖面、钻井资料和古生物资料,研究了该区域内泥盆系台盆沉积体系发育特征。研究表明黔南-桂中凹陷泥盆系呈现碳酸盐岩孤台和深水台盆相间分布的沉积格局,主要发育五种台盆类型:泥岩-陆屑浊积岩型、泥岩-泥灰岩型、泥岩-硅质岩型、硅质岩-灰岩型、硅质岩(泥岩)-火山岩-火山碎屑浊积岩型。层序地层分析后认为,其层序界面一般表现为岩性转换面,少数表现为冲刷侵蚀面,层序发育完整、连续性好,能很好地反映海平面变化历史。

Abstract:

On the basis of the previous study and making use of the study on outcrop, well drilling data and paleontology adequately, the characteristics of platformbasin sedimentary system in Qiannanguizhong Sag in Devonian are summed up. Sedimentary system in the basin in Devonian includes mudstone classic turbidity, shalesiliceous rock, siliceous rocklimestone, mudstonemarlite source rock and siliceous rockformation mechanismvolcaniclastic turbidity. Sequence stratigraphy is used to analyze and research the platformbasin system deeply. Sequence boundary always represents as the surface of the change of lithology. And a few boundaries appear erosion surface. Nevertheless, integrated sequence could response to change of sea level.

Key words: Qiannanguizhong Sag, Devonian, platformbasin, sedimentary system, sequence stratigraphy
