Based on the characteristics of tectonic setting, palaeogeographic outline, sedimental lithofacies and stratigraphicsequence in China, the study and analysis of distribution sequence and lithofacies of Jurassic and its petroliferous geo-logic conditions has been made. The Jurassic sedimentary provinces, bounded with Helan Mt. -Longmen Mt. -Kangdian uplift-Ailao Mt. are divided by the authors into eastern and western parts.

Based on the characteristics of tectonic setting, palaeogeographic outline, sedimental lithofacies and stratigraphicsequence in China, the study and analysis of distribution sequence and lithofacies of Jurassic and its petroliferous geo-logic conditions has been made. The Jurassic sedimentary provinces, bounded with Helan Mt. -Longmen Mt. -Kangdian uplift-Ailao Mt. are divided by the authors into eastern and western parts. The east is dominated by north- east, north- north- east oriented faulted basins, the west by near east- west oriented intermontane basins. Inearly Jurassic, the coastline area in the east became a part of the Pacific, while the inland province became rift faults- depressions and inland depressed basins; Xizang(Tibet) area in the west was marine sedimentary province, Xin-jiang was inland one while the others were all intermontane basin sedimentary province. In late Jurassic, as upliftingof the eastern continental crust and the Pacific plate subducted toward the continent, fierce volcanic activities occurredin thd east, forming a large of volcanic rocks or volcanic- sedimentary rocks in the basins. During that period,Xizang province remained as the same, but the ocean area became smaller, the other basins would become shalloweras a result of crust uplifting and long-term depositing, thus a set of red clastic substances were formed. Having ana-lyzed tectonic setting and sedimentary environment of Jurassic, the authors point out that Jurassic is not only a domi-nant coal-generated sequence, but also is an important petroliferous one, having extensively favorable petroliferousprospects.

本文根据中国大地构造环境、古地理轮廓、沉积岩相与地层层序特征研究了我国侏罗系的分布、层序及岩相,并分析了我国侏罗系的含油气地质条件。作者以贺兰山—龙门山—康滇隆起—哀牢山为界将中国侏罗纪沉积区分为东西两部分,东部以北东、北北东向的断陷盆地群为主,西部则以近东西向的山间盆地为主。侏罗纪早期东部沿海一带为太平洋的一部分,东部内陆区为裂谷型断陷—坳陷和内陆坳陷型盆地;西部的西藏区为海相沉积区,新疆为内陆沉积区,其他区为山间盆地沉积区。侏罗纪晚期,由于东部陆壳继续抬升,太平洋板块向大陆俯冲,使得中国东部火山活动非常剧烈,在盆地中形成了大量的火山岩层或火山—沉积岩层。中国西部西藏地区仍为海域,但范围缩小。其余沉积盆地由于地壳上升和长期沉积而变浅,沉积了一套红色碎屑物质。作者在分析了侏罗纪的构造环境和沉积条件后指出,侏罗系不但是我国的一个重要成煤层系,而且也是一个重要的含油气层系,有着广阔的含油气前景。

The Triassic sedimentary strata bounded by two regional unconformities in southwestern Guizhou can be divided into seven sequences including carbonate sequencs Ⅰ to Ⅳ and siliciclastic sequence Ⅴ to Ⅶ, which are identified as type 1 sequence, except sequence Ⅰ.

The Triassic sedimentary strata bounded by two regional unconformities in southwestern Guizhou can be divided into seven sequences including carbonate sequencs Ⅰ to Ⅳ and siliciclastic sequence Ⅴ to Ⅶ, which are identified as type 1 sequence, except sequence Ⅰ. The regional sequence stratigraphic framework established on the basis of integrated data on the spatial pattern of lithological units, the chronostratigraphy and sequence-stratigraphy suggests that: (1) the carbonate sequences developed on platform are characterized by distinctive sequence boundaries, generally containing transgressive and highstand systems tracts with lack of lowstand systems tracts, and there is no the actual condensed section whereas relevant strata called slow rate depostion section.The diagenesis process commonly has a significant influence upon them; and (2) the evolution of depositional basins in the study area underwent approximately two stages, from extensional basins on the passive continental margin during Early Triassic when the major rise in the regional sea-level to the compressional peripheral foreland basin during Mid-Late Triassic when having an overall fall in the regional sea-level and two subdivisions of the early and late phrases. In conclusion, the diverse sequences and framework presented in this paper were formed in different ages and phrases of evolution of the depositional basin.

黔西南地区三叠系是被两个区域性不整合面所限定的一套地层,它可进一步划分为七个层序。除层序Ⅰ外,均为类型Ⅰ层序,其中Ⅰ—Ⅳ为碳酸盐层序,Ⅴ—Ⅶ为硅质碎屑层序。综合岩石地层单位空间分布及相互关系、层序地层、年代地层等各方面资料,建立的区域性地层沉积格架表明:①碳酸盐台地上地层层序特征是─—层序界面清楚;层序一般由海侵体系域和高水位体系域组成,缺少低位体系域;无真正的凝缩段,与凝缩段相当的地层称低速沉积段;成岩作用的影响极为明显。②研究区内的沉积盆地大体经历了两个发展阶段─—第一阶段(早三叠世)为伸展型被动大陆边缘盆地,也是区域性海平面主体上升时期;第二阶段(中晚三叠世)为挤压型周缘前陆盆地,也是区域性海平面主体下降时期,该阶段可进一步划分为早、晚两个时期。在沉积盆地发展的不同阶段和时期,分别形成各具特色的地层层序和沉积格架。

he measurements and analyses of magnetic fabrics were done for Late Quaternary transgressive sedimentary profile at Caoyang in Shanghai.According to the value characteristics of magnetic fabric parameters,the profile is divided into five sections.Each fits in with the Late Quaternary sedimentary sequence in the Yangtze River Delta and is comparable with microfossil and isotope data.The assemblage of K,P,F,L and q can be used to distinguish,with high resolution,hard soil and marine facies and define the boundaries among marine facies.Therefore,this may be a new method for stratigraphic division and correlation....

利用上海地区曹阳孔的沉积磁组构资料,对该孔所揭露的地层进行划分。其结果与古生物、同位素及沉积物粒度分析资料相吻合,五个层段对应于晚第四纪冰后期以来长江三角洲地区的地层层序特征。研究认为,K、P、L、F、q组合特征是分辨古土壤与海相层、海相层内部沉积相变界线的高分辨率标志,可作为地层划分的新依据。
