摘要

通过岩心观察、薄片鉴定、X衍射矿物分析，对鄂尔多斯盆地西南部刘家沟组重力流沉积的岩石类型及特征、成因进行研究。结果表明，刘家沟组取心段发育灰紫色粉砂岩、砾屑混积岩以及薄层黑色泥岩。粉砂岩主要组分为石英、岩屑、长石、泥晶方解石及杂基，具杂基支撑结构，发育沟模、粒序层理、火焰状构造、包卷层理、鲍马序列等浊流沉积特征，为浊积岩。砾屑混积岩发育大量砾屑及填隙物，填隙物由陆源碎屑颗粒、内碎屑及基质组成，发育泥质撕裂屑、基质支撑结构、颗粒无定向排列、与上下泥岩突变接触等沉积特征，为碎屑流沉积。研究认为，早三叠世勉略洋盆并未完全闭合，对鄂尔多斯盆地西南缘产生海侵影响，形成混积岩层，在正宁一带发育潟湖沉积，并存在斜坡，在C3钻井处发育碎屑流-浊流为主的重力流沉积。

Abstract

Through core observation

thin section identification

and X-ray diffraction mineral analysis

the rock types and characteristics

and the genesis were studied. The results show that the core section of Liujiagou Formation develops grayish purple siltstone

rudaceous mixed rock and black mudstone. The siltstone was mainly composed of quartz

rock debris

feldspar

micrite calcite

and matrix

with a matrix-supported fabric

and developed turbidite sedimentary characteristics such as groove casts

graded bedding

flame structures

convolute bedding

and Bouma sequences

identifying it as turbidite. The mixed rock contained a large amount of gravel intraclast and interstitial material

with the latter composed of terrigenous clastic particles

intraclasts

and matrix. It exhibited sedimentary characteristics such as muddy tear-shaped clasts

matrix-supported structure

randomly oriented particles

and abrupt contact with the overlying and underlying mudstones

suggesting it was debris flow deposition. The study suggests that the Mianlue Ocean during the Early Triassic was not completely closed and had a marine transgression impact on the southwestern margin of the Erdos Basin

forming mixed rock strata. Lagoon sediments developed in the Zhengning area

with slopes present

and gravity flow sediments dominated by debris flow-turbidity current were developed at the place of Well C3.
