塔里木盆地卡拉沙依组砂泥岩段地层对比与沉积相研究
Stratigraphic correlation and sedimentary facies of the sandstone and mudstone section in the Kalashayi formation of Tarim Basin
摘要
Abstract
The sandstone and mudstone section in the Carboniferous Katashayi formation of Tarim Basin has been studied and analyzed for stratigraphic correlation, strata contact relationship, and the types and distribution of sedimentary facies based on a huge data of core observation, outcrop, wireline logging, mud logging and outcrops. The study shows that the Kalashayi formation had developed interbedded sandstone and mudstone section across most part of the basin; the sediments are coarse toward southeast and contain gypsum - salt rock in the southwest; the sandstone and mudstone section is in unconformable contact with overlying limestone formation and dominated by continental sedimentation of fluvial - delta facies in most of the basin, and there starts to occur marine facies of tidal flat, lagoon and open platform from Bachu to the southwest. The palaeogeomorphology of Tarim Basin in this stage was high in the east and low in the west, with sediment source coming from the east of the basin.关键词
