塔西南昆仑山前地区晚白垩世沉积演化
Evolution of sedimentary environment in late Cretaceous,Kunlun Mountain Front, Tarim Basin
摘要
Abstract
In order to reveal the sedimentary facies in late Cretaceous of Kunlun Mountain front, Tarim Basin, according to the outcrops, log information and the analysis of sample testing, the results show that the upper Cretaceous of Kunlun Mountain front can be divided into four formations from bottom to top: Kukebai, Wuyitake, Yigeziya and Tuyiluoke formation. Brownish red sand and silt rocks in the lower and greyish-green mudstone clip limestone of upper Kukebai formation. Wuyitake and Tuyiluoke formations have similar lithology, anointed with mudstone. Red limestone is the main rocks of Yigeziya formation. Strata of upper Cretaceous get thinner from east to west. Two large scale transgression-regression cycles can be distinguished in upper Cretaceous, and each formation or section developed typical and relatively single sedimentary facies. From bottom to top developed braided delta, evaporative sand-mud supratidal zone, carbonate platform and evaporative sand-mud supratidal zone.关键词
