| 1. | New advances in the research on the upper jurassic in the middle of the north qiangtang basin 北羌塘盆地中部上侏罗统研究新进展 |
| 2. | Assemblages first demonstrate that not only the upper jurassic strata but also the highest 首次记述了该区最高层位的雏蛤组合,同时,新发现的 |
| 3. | Discussion on the stratigraphic classification of the upper jurassic of donghu region in qiangtang basin 羌塘盆地北部上侏罗统东湖剖面的划分与对比 |
| 4. | Gelological structure and hydrocarbon - bearing property of upper jurassic system in the southeast of west siberia 西西伯利亚东南部上侏罗统地质结构和含油气性 |
| 5. | ( 4 ) based on the above - mentioned studies , the tertiary sequence of middle - upper jurassic series is identified , divided and compared ( 4 )在上述研究基础上,对研究区中?上侏罗统进行三级层序的识别、划分和对比。 |
| 6. | In the upper jurassic to tertiary , there is the alkali diagenetic ambient , in which the inter - pore fluid is inherited from the buried syngenetic water , i . e . , alkali saline 上侏罗纪至第三系为碱性成岩环境,隙间流体继承了封存同生水特征,为碱性盐卤水。 |
| 7. | The formation and evolution of sequence stratigraphy of middle - upper jurassic series is affected by change of global sea level , tectonic uplift and subsidence , sedimentary supply and climate conditions 中?上侏罗统层序地层的形成演化受全球海平面变化、构造隆升与沉降、沉积物供给以及气候条件的综合影响。 |
| 8. | ( 5 ) the study indicated that the formation and evolution of five tertiary sequence of middle - upper jurassic series correspond to five rise and fall cycles of sea level , and finally ends in marine deposits ( 5 )研究表明,中?上侏罗统五个三级层序形成演化对应相对海平面的五次升降变化旋回,并最终结束海相沉积。 |
| 9. | In the present work , sequence - paleogeographic mapping is implemented on the s econd member of the upper triassic xujiahe fm . and the upper jurassic ponlaizhen g fm . in western sichuan , china , with system tracks taken as the mapping units 研究重点选择上三叠统须家河组二段和上侏罗统蓬莱镇组,按体系域进行层序-岩相古地理编图。 |
| 10. | At the late stage of upper jurassic ( 135ma ) , the provenance areas underwent intense and sustained uplift and denudation . in the period of lower cretaceous , the tectonic setting of the provenance areas turned into strike - slip 侏罗纪末( 135ma )到早白垩世源区产生剧烈的持续上升和剥蚀,早白垩世晚期,源区的构造转换为拉张。 |
