柴达木盆地西部北区新近纪沉积体系演化及其控制因素
摘要
Abstract
There are west sedimentary source and east sedimentary source developed in the altun slope in Neogene in northwest Qaidam Basin, the west sedimentary source includes Canchaigou water system, Xianshuiquan water system, Honggouzi water system and Yueyashan water system which mainly develop fan delta and turbidite fan and lake depositional system that are mainly steep slope type. The east sedimentary source includes Hongsanhanyihao water system and Niubiziliang water system which mainly develop the fan delta and bar and lake depositional system that are gentle slope type. There are carbonate and gypsum sedimentary systems developing in the basin center. For all kinds of sedimentary systems, which lie in the edge of the basin, its development and e-volution are controlled by the altun rupture and its derived sub-ruptures activities by the study. These ruptures' activities often have many features such as stages,multi-cycles and complexities. But the development and evolution of carbonate and gypsum sedimentary system are controlled by the ancient geography relief which has many low uplifts and multiple sedimentary centers in the basin.关键词
