| 摘 要： | 详细研究了黄县煤田早第三纪断陷盆地沉积填序列和沉积体系，研究了基准面旋回特点，进行了高分辨率层序地层划分。研究表明，黄县断陷盆地下第三系为１个构造层序，是一个完整的原型断陷盆地沉积充填序列。可划分出２个三级层序，且具有三元结构，即由低水位、水进和高水位体系域组成；层序Ｉ低水位体系域由早期和晚期两部分组成，层序Ⅱ高水位体系域亦有早期和晚期两部分构成。主要沉积体系有：扇三角洲体系、湖底扇体系、辫状河三

| Abstract: | This paper investigates in detail the depositional succession, and depositional systems of the coal bearing strata in the Huangxian Paleogene faulted basin, analyses the base-level change and the division of high-resolution sequences. The study shows that the Paleogene system in the Huangxian basin is a tectonic sequence and a intact original faulted basin-filling succession. Two third-order sequences can be recognized in this succession. The sequences are composed of three units, the lowlevel, the transgressive and the highlevel systems . The lowlevel systems of the first sequence consist of two part, the early stage and the later stage . The highlevel systems of the second sequence are also subdivided into two parts, the early and the later highlevel systems. The main depositional systems are the fan delta, sublacustrine bottom fan, braided river delta, lacustrine and turbidite fan systems. |
