  1. Based on available data, the study on regional structure, sedimentary reservoir and source rock characteristics shows that the basins in south china sea had experienced sedimentary evolution in faulting period and depression period, deposited thick cenozoic formation, upwardly developed alluvial fan facies, river - lake facies coastal swamp facies coastal facies, neritic facies and bathyal deposit system, regionally had 3 source rocks of eocene, oligocene and miocene, 3 reservoirs of pre - cenozoic basement buried bill, oligocene sandstone and miocene reef, with pliocene and pleistocene neritic facies and bathyal shale as regional caprock

    摘要以現有資料為基礎,通過對區域構造、沉積儲層、烴源巖特徵等基礎石油地質條件研究,認為南海海域各盆地經歷了斷陷期和坳陷期沉積演化,沉積了巨厚的新生代地層,自下而上發育了沖積扇相、河湖相、濱岸沼澤相、濱海相、淺海相、半深海相沉積體系,區域上存在始新統、漸新統和中新統3套烴源巖,前新生代基巖潛山、漸新統砂巖、中新統生物礁3套儲層,區域蓋層為上新統和更新統淺海半深海相泥巖。
  2. They are all called yangping period denudation surface and were formed in the miocene epoch and the pliocene epoch

    魯中南山地東部山頂部位的熔巖被分佈面也相當于仰平期剝夷面。
  3. The volcanic rock age and the age of the qiangtang formation determined the wudaoliang group between 20 - 5ma, discovering a flood of spore and pollen with ostracods fossils ( regard eucypris as principle ), which are miocene epoches typical numerator, therefore wudaoliang group accumulate in miocene epoch is doubtless ; 9 - 2ma are the age of the suonahu formation based on the data of the esr, which were characteristic of later period in miocene epoch - pliocene epoch, spore and pollen with fossil all were miocene epoch period

    由火山巖和覆于其上的羌塘組的年齡限定五道梁群的沉積時間為20 - 5ma ,五道梁群中發現大量的孢粉和介形蟲化石(以eucypris為主) ,分析認為它們都是中新世時期的典型分子,因此五道梁群的沉積時間為中新世是無疑的;嗩吶湖組的esr測年數據范圍為9 - 2ma ,代表中新世晚期?上新世時期,孢粉和化石都具有中新世時期的特徵。
  4. Based on the analyses of structural features, volcanic activities, sequence construction and so on, it is believed that liaohe basin has experienced the period of dextral transtensional stress field in late jurassic - early cretaceous, middle and late paleocene, late eocene, miocene, and also the period of sinistral compresso - shear stress field in late cretaceous, early paleocene, early and middle eocene, oligocene, pliocene

    對構造現象、火山活動、層序充填型式等多種實際資料的分析表明:遼河盆地經歷了侏羅紀末白堊紀早期、古新世中後期、始新世中後期、中新世等右旋張扭應力場作用階段,以及白堊紀晚期、古新世初期、始新世早中期、漸新世、上新世以來等左旋壓旋應力場作用階段。
  5. Comparison and study of the biotic characters in the jinggu and longchuan basins in yunnan province show that : ( 1 ) the two basins underwent the developing period, expanding period and shrinking period from early miocene epoch to pliocene epoch ; ( 2 ) the climate in the region was dry in early miocene epoch, warm and humid in middle - late miocene epoch and dry in pliocene period ; ( 3 ) the basins expanding in middle - late miocene epoch formed a semi - deep - lake to deep - lake environment

    通過對雲南景谷盆地及隴川盆地新生代生物群特徵的對比,探討了新生代兩大盆地環境演變:早中新世到上新世為湖盆發展期湖盆擴大萎縮期,氣候為早期的千燥中新世早期的溫暖濕潤中新世中晚期的寒冷陰濕上新世的乾燥,而中新世中晚期湖盆的擴大形成的半深湖深湖環境為油氣的形成提供了有利條件。
