准噶尔盆地东缘中侏罗统头屯河组层序地层与沉积演化
|
摘要
为揭示准噶尔盆地东缘中侏罗统头屯河组(J2t)层序地层特征及其沉积充填规律,结合露头、岩心及测井资料并运用高分辨率层序地层理论,对研究区头屯河组层序地层进行划分对比,对其沉积相展布特征和沉积环境演化规律进行研究。结果表明:头屯河组可划分出个1个Ⅲ级旋回、3个Ⅳ级旋回及9个Ⅴ级旋回,沉积物岩性以砂砾岩和泥岩为主,沉积环境主要为辫状河、辫状河三角洲和滨浅湖,发育向上"变深"对称型和非对称型的两种结构类型。头屯河组沉积时期湖泊较浅,沉积基底平缓,湖泊边缘坡度小,在头屯河组下段(J2t1)时期到头屯河组上段(J2t2)段时期经历了湖侵演变过程。结合研究区的层序地层和沉积相展布特征,认为研究区中侏罗统头屯河组具有辫状河、辫状河三角洲及湖泊3种沉积环境相结合的沉积演化模式。
The present paper deals,on the basis of high-resolution sequence stratigraphic theory,outcrops and well logs,with the sequence stratigraphic division and correlation,sedimentary facies distribution and sedimentary environmental evolution of the Middle Jurassic Toutunhe Formation,aiming at revealing the sequence stratigraphic characteristics and sedimentary evolution of the Middle Jurassic Toutunhe Formation on the eastern margin of the Junggar Basin,Xinjiang. The Middle Jurassic Toutunhe Formation consists of one third-order,three fourth-order and nine fifth-order depositional cycles,and comprises the deepening-upward symmetric and asymmetric types of sequence architectures. The sediments are mainly composed of sandy conglomerates and mudstones. The sedimentary environments are separated into braided river,braided delta,and littoral and shallow lake with the lake transgressive evolution spanning from the depositional period of the first member of the Middle Jurassic Toutunhe Formation( J2 t1) to the depositional period of the second member of the Middle Jurassic Toutunhe Formation( J2 t2). The sedimentary model is proposed herein showing the sedimentary evolution of the braided river facies,braided delta facies and lacustrine facies in the Middle Jurassic Toutunhe Formation in the study area.
