| 3. | Distribution characters and exploration potential of mesozoic sea facies sedimentary strata in the south china sea basin 南海盆地中生代海相沉积地层分布特征及勘探潜力分析 |
| 4. | The qiangtang basin , having the most complete and extensive marine sedimentary strata during jurassic , is the second larger mesozoic marine sedimentary basin 藏北羌塘盆地地处青藏高原腹部,是我国中生代第二大海相沉积盆地,侏罗系是羌塘盆地发育最全、分布最广泛的海相沉积层系。 |
| 5. | Thirdly , by comparing with holocene strata of the coastal plain of shandong peninsula , sedimentary strata of this area are divided into four layers , and sedimentary environments are comfirmed 再次,通过与山东半岛滨海平原全新统地层进行对比,对本沉积区地层进行划分并确定各层沉积环境。 |
| 6. | According to the characteristic of sedimentary stratum and the study of geochemistry in binbei area , source rocks of each layer become thicker from north to south . source rocks of south depressed center heiyupao , south wuyuer sunkeness and other area on the binzhou railway are best development 根据滨北地区地层的沉积特点和地球化学研究,各层源岩表现为从北向南逐渐增厚,其中黑鱼泡凹陷中部以南、乌裕儿凹陷南部、临近滨州线的其它地区源岩发育最好。 |
| 7. | The qiantang basin , having the most complete and extensive marine sedimentary strata during jurassic , is the second larger mesozoic marine sedimentary basin . although many achievements are obtained in recent years , the research are still only involved in second - or third - order of mesozoic sequence . on the base of sedimentation facies analysis of matuo formation , high frequency sequence are studied 藏北羌塘盆地地处青藏高原腹部,是我国中生代第二大海相沉积盆地,侏罗纪是羌塘盆地发育最全、分布最广泛的海相沉积层系近年来,羌塘盆地在层序地层方面的研究已取得不少成果,但其层序地层研究多涉及中生代二级或三级层序,至于高频层序,尚未进行详细的研究。 |
| 8. | By studying the lithologjcal and mineral parameters ( pebbled elastics percent ratio , clastic maturation index , heavy crop stability factor ) of mesozoic sedimentary strata , the result shows that the northern boundary of present basin is near to the boundary of original basin and the moving distance of elastics is short , but the southern boundary of present basin is far from the boundary of original basin and the moving distance of elastics is long . the fades of northern basin are mainly delta fades and the fades of middle and southern basin are lacustrine fades 通过对盆地中生代沉积地层中各种岩矿参数(碎屑岩含砾百分比、碎屑成熟度指数和重矿物稳定系数)分析和综合研究认为,今盆地北部距离原始盆地沉积边界较近,碎屑物搬运距离较短;南部距离盆地古沉积边界较远,沉积物搬运距离较远;中生代盆地北部主要为三角洲沉积相,中南部为湖泊相沉积。 |
| 9. | The lower paleozoic continent marginal sedimentary strata in the north kunlun massif are sinian - cambrian alajiaoyi group and ordovician pishigaisayi formation . the former is composed of high maturity flysch deposit , the later consist of continental shelf deposit such as carbonate and slate and sandstone . these rocks implies that they might form at passive continental margin 与其曼于特蛇绿岩相关的早古生代边缘沉积岩在昆北地块上为震旦?寒武系阿拉叫依岩群、奥陶系皮什盖萨依岩组,前者为一套成熟度较高的陆源碎屑复理石沉积,后者为碳酸盐岩和含碳板岩砂岩等陆棚沉积,显示其具被动陆缘性质。 |
