二连盆地白音查干凹陷早白垩世腾格尔组沉积特征及物源探讨
|
摘要
根据岩芯、录测井、地震以及其它分析化验资料,对白音查干凹陷早白垩世腾格尔组的沉积特征、沉积相类型及其分布规律进行了详细研究。结果表明,腾格尔组发育扇三角洲、辫状河三角洲、湖泊和浊积扇4种沉积相类型,扇三角洲分布在北部陡坡带,辫状河三角洲分布在南部缓坡带,从盆地边缘到盆地中心,沉积相由扇三角洲、辫状河三角洲沉积逐渐转变为半深湖-深湖沉积,在三角洲侧翼发育滨-浅湖相沉积,在三角洲前缘、前三角洲以及半深湖中发育浊积扇沉积,整体呈东西洼凸相间、南北隆凹成带的格局,这种沉积格局受盆地周边断层和古地形控制。利用岩石组分和重矿物成分进行物源分析,认为白音查干凹陷沉积物主要来自凹陷北部的巴音宝力格隆起和凹陷南部的赛呼都格凸起方向,并具有多期次、阵发性、近物源的特点,母岩岩性主要为沉积岩,其次为岩浆岩,见少量变质岩。
Based on core description, electric logging, mud logging, core analysis data, seismic survey, etc., the sedimentary facies types and characteristics of early Cretaceous Tenggeer Formation, Baiyinchagan Sag, were studied in detail, as well as their distribution pattern. The research shows that fan delta, braided delta, lacustrine facies and turbidity fans were developped in this formation, of which the fan delta is located along the steep northern border and the braided delta found along the gentle southern slope. In addition, from the margin to the depocenter of Baiyinchagan Sag, the sedimentary environment gradually changed from fan delta or braided delta to semi-deep and deep lakes, and on the flank of fan delta or braided delta, the shore and shallow sediments were deposited. The turbidity fans are distributed in the delta front zone, pro-delta and semi-deep and deep lacustrine zones. Generally speaking, the sedimentary facies are different from the east to the west of Baiyinchagan Sag and were differentiated between the southern and the northern parts, which was controlled by the neighboring faults and the basin palaeotopography. Based on the analysis of sandstone detrital components and heavy minerals, the sediments of Tenggeer Formation in Baiyinchagan Sag came from the Bayinbaolige swell and Saihuduge salient, with the characteristics of multiphase,spasm and closing to the source rocks. The results also illustrate that the source rocks were mainly the sedimentary, and in lesser amount the igneous, with little contribution of the metamorphics.
