中国华北地台二叠纪前陆盆地的发现及其证据
DISCOVERY AND EVIDENCE OF THE FORELAND BASIN IN THE NORTH CHINA PLATFOR MIN THE PERINIAN PERIOD
摘要
Abstract
The symchronous cyclic sequence stratigraphy in the Peri nian was contrasted by the sedimentary sequence boundary of the carbonate rock-silicoclastics rock,resulted in the suddent occurrence of transgression controlled by the Cosmic-Earth system. It is discovered firstly that the North China platform had been transformed from stable Cratonic basin to the sequeezed foreland basin of trust orogenic wedge since Late Carboniferous to Early Perinian. The main evidence is that,①there is the huge thick infilled sequence and inverse graded sequence from mid-late Zisong stage (CS6-PS4 sequence),Nonglin stage and Xixia stage(PS6-PS28) in the northern part of the North China;②and at the same time, the non-compensated marin mudstones and siliceous stones deposited in the infilled sequences downlap bottom of the infilled sequence of the southern area of the North China are discovered;and ③ the backstepping ramp carbonate sequences belong to the forebuldge of appeared in the southern part of the North China. Wide existence of recycle-orogenic trust sources such as nodular-like siliceous concretion,tuff,tuffaceous deposition, the sedimental parragenetic series of slumping,turbidite, gravity flow and flysch in the sedimentary basin during the Perinian period; inmultipe times and wide development of the volcanic island arc and volcanic eruption event, the variation of the reversal of magnetic field and paleolatitude, etc.all indicate that the North China platform, Siberia-Xingmeng fold belt and convergent, collision and trust belt and foreland basin exist; and also prove that the Perinian North China platform is a foreland basin of the backarc property.关键词
