To reconstruct the evolution and variability of the east asian monsoon during the late cenozoic on millennial , orbital and tectonic time scales . 3 . to identify and better understand the links between tectonic uplift , erosion and weathering hemipelagic deposition , and climate change , including the evolution of the asian monsoon and the neogene global cooling Odp184航次1999年2月至4月間在中國南海進(jìn)行鉆探取樣,通過鉆取半遠(yuǎn)洋沉積,以期說明南海的新生代歷史,包括它的生物地層學(xué)、巖石地層學(xué)、年代學(xué)、古氣候?qū)W和古海洋學(xué);重建千年級的晚新生代東亞季風(fēng)的發(fā)展和演化、軌道和構(gòu)造時間尺度;識別和更好地理解構(gòu)造抬升、侵蝕和風(fēng)化、半遠(yuǎn)洋沉積和氣候變化,包括亞洲季風(fēng)和晚第三紀(jì)的全球變冷。
A general survey of the formation , evolutionary histories of continental orogenic belts both in china and abroad reveals that orogenic belts have often undergone numerous and varied tectono - evolutionary stages , such as palaeocontinental break - up , ocean - land transition , continental matching - collision , intracontinental extension - basin - range coupling , and new tectonic uplift ( intracontinental orogeny ) , which are respectively accompanied by characteristic volcano - magmatisms 縱觀我國以至全球的大陸造山帶形成、演化歷史,一個造山帶往往經(jīng)歷了古大陸裂解、洋陸轉(zhuǎn)換、陸塊拼合碰撞、陸內(nèi)伸展盆山耦合和新構(gòu)造隆升(陸內(nèi)造山)等眾多不同的構(gòu)造演化階段,這些不同的構(gòu)造演化階段和不同的構(gòu)造環(huán)境均有特定火山巖漿作用與之相伴。
Scanning the formation - evolutionary histories of continental orogenic belts in both our country and whole workd , an orogenic belt has often undergone numerous and various tectono - evolutionary stages , such as palaeo - continental break - up , ocean - land transition , continental matching - collision , intracontinental extension - basin - range coupling , new tectonic uplift ( intracontinental orogeny ) , etc . , which are respectively companied with characteristic volcano - magmatism 縱觀我國以至全球的大陸造山帶形成-演化歷史,一個造山帶往往經(jīng)歷了古大陸裂解、洋陸轉(zhuǎn)換、陸塊拼合-碰撞、陸內(nèi)伸展-盆山耦合和新構(gòu)造隆升(陸內(nèi)造山)等?多不同的構(gòu)造演化階段,這些不同的構(gòu)造演化階段和不同的構(gòu)造環(huán)境均有特定火山巖漿作用與之相伴。
With the tectonic uplift of the source area and the climate turning dry , the coal forming period was over , the fluvial system and fluvial - delta system became to play a major role . based on the study of former researchers and the theory of deep basin gas reservoir forming , the deep basin gas trap in the ordos basin is analyzed and is supposed to form in the ramp of the basin . it is supposed that the hydrocarbon of the deep basin gas trap is mainly composed of coal , carbonate and carbonaceous shale and with the " upper water seal " in the north of the study area the g 根據(jù)深盆氣成藏理論和前人的研究成果,分析了深盆氣藏的分布類型,認(rèn)為鄂爾多斯盆地深盆氣藏屬于盆地斜坡成藏類型;認(rèn)為深盆氣的源巖以煤、炭質(zhì)泥巖、暗色泥巖和碳酸鹽巖為主;北部氣水倒置、東部露頭區(qū)有天然氣逸出;氣藏具有多重壓力系統(tǒng);成藏機(jī)理主要是氣體動態(tài)的運(yùn)移與聚集,穩(wěn)定的構(gòu)造背景有利于氣藏的大面積保存。

This preliminary research focus on the tectonic uplift in late mesozoic - early cenozoic after the main collision oregeny to understand more and detail on the total process of tectonics evolvement in east dabie mountain and beihuaiyuan area . the research works that have been done are : apatite fission track dating , apatite thermal - evolvement patterns ; the fluid characteristics including fluid inclusions " microthermometer , the compositions , 5 d - 8 18o , and their geochemistry , thermodynamics parameters 為更全面了解東大別山及北淮陽地區(qū)大地構(gòu)造完整的演化,并為之提供研究實例積累,本研究主要從熱年代學(xué)及造山后流體特點角度對東大別山及北淮陽構(gòu)造區(qū)碰撞造山后中生代未-新生代初構(gòu)造隆升活動進(jìn)行了初步探討。
