Song Liao Basin located at upper mantle-arching belt of the east part of Europe-Asia plate belongs to the mid-basin of continental crust.When the upper mantle-doming up,it acted as a hot-dome.Plenty of tensile faults were formed subsequently.Song Liao Basin was formed by the controlling of these crust faults.In early stage,it behaved with characteristics of a rift basin,but in middle to final stages,it gradually changed to a New-intracratonie composite basin,the influence of the isostatic adjustment activity of the crust and underthrust of pacific plate.So that the original depression-rift belts evolved gradually to a depressi- on.Although Song Liao Basin is a continental basin,it has a large area of deep-lacustrine deposits with abundant nutrition to form good source rocks,due to action by twice global plate activities during the Middle Cretaceous.The long term geothermal hot current and high geothermal temperature that had controlled the deagenesis and the matomophism of organic matters in the basin,therefore the source beds exhibited lower threshold temperature of oil generation and rapid evolution of oil and a short maturity zone.On the plane,deep lacustrine facies in this depression where the early rift basin coincided with latter depression and its adjacent parts are most favorable for oil accumulation.

松辽盆地属于陆壳中盆地,处于欧亚板块东部的上地幔拱起带上。盆地就是在这拱起的背景上产生热穹窿作用,造成大陆初始张裂,在壳断裂的控制下形成。早期具有裂谷特点,中后期由于地壳均衡调整作用和太平洋板块俯冲影响由原来裂陷地带演化为坳陷,成为新克拉通内复合型盆地。松辽盆地虽是陆相盆地,但在白垩纪中期的两次全球性板块活动控制下,造成大面积富营养深水湖相沉积,为良好的生油岩。由于长时间的高热流、高地温条件控制了盆地的成岩作用和有机变质作用,因而盆地生油层表现出生油门限浅、演化快、成熟相带短的特点。在平面上早期裂谷与后期坳陷相重合的深坳陷深水相及其两侧地带含油最丰富。

According to the distribution and development of the strata and fossils, western Yunnan may be divided into the Baoshan-Tengchang, Gengma-Meng-lian and Lanping-Pu'er areas. In the Baoshan-Tengchang area, the Paleozoic stata are particulary well developed; in the Gengma-Menlian area, the late Paleozoic strata dominate; in the Lanping-Pu'er area, the Mesozoic strata are very extensively distributed.The tectonics of western Yunnan are rather complex.

According to the distribution and development of the strata and fossils, western Yunnan may be divided into the Baoshan-Tengchang, Gengma-Meng-lian and Lanping-Pu'er areas. In the Baoshan-Tengchang area, the Paleozoic stata are particulary well developed; in the Gengma-Menlian area, the late Paleozoic strata dominate; in the Lanping-Pu'er area, the Mesozoic strata are very extensively distributed.The tectonics of western Yunnan are rather complex. During the Middle Proterozoic era, two blocks were welded in the Ailao Mountain belt, extending from Malutang of Xinping and Panzhihua region of Yuanyang in Central South Yunnan, and formed a NW-SE-striking collage. The northeastern side of the collage is a highmedium temperature-low-medinu pressure metamor-phic belt, with typical minerals of andalusite, cordierite, kyanite, staurolite and garnet. The southwestern side is a low-medium temperature-high medium pressure one, with typical minerals of glaucophane and stilpnomelane. Besides ophiolitic melange and opiolite suite were found, from which pyroxenite and gabbro Were dated as 910 Ma and 1340 Ma respectively.During the end of the Middle Proterozoic, the two blocks were once again welded along the Changning-Yunxiang-Lincang Menghai belt in southwestern Yunnan, forming a NNW-SSE collage. The southwestern side is a lowmedium temperature-high-medium pressure metamorphic beJt whose typical minerals are glaucophane, barroisite, stilpnomelane and phengite, while the northeastern side is a high-medium temperature-low-medium pressure one characterized by an assembladge of andalusite, staurolite, cordierite, sillimanite and hypersthe-ne. The granites dated as 715, 784 and 789 Ma are intruded the Lancang Group and the Chongshan Group of the upper wall of the collage.In the middle Cretaceous time, the Baoshan-Tengchong region (along the present Western border or wesster Yunnan), which was then a portion of the Indian Oldland, began to separate from the Gondwana land, and drifted northward. At the end of the Eocene, it collided and incorporated with the Eurasian plate.

根据地层古生物的分布和发育情况,可将云南西部划分为保山—腾冲区、耿马—孟连区和兰坪—普洱区。保山—腾冲区古生代地层特别发育,耿马—孟连区主要为晚古生代地层,兰坪—普洱区和生界分布特别广泛。云南西部构造复杂,中元古代时,两个块体在哀牢山一带形成拼结带。中元古代末,两个块体在昌宁、临沧一带形成拼结带。白垩纪中期,保山—腾冲区所属的印度古陆与冈瓦纳古陆分离且向北漂移;始新世末,与欧亚古陆碰撞合并。

In Cretaceous, Tibet was part of the East Tetheys Ocean. Theexistence of Yaluzangbu Trough and Bangonghu--Nujiang Rift causeddifferent development of bivalves on the two sides of the trough.Three provinces are recognised:the Himalayan province, the Gandese-Nianqing--Tanggula province and the Qiangtang province. Characteristicsof bivalve assemblages, their distribution and relationship with coexis-ting fossils are described in detail. These studies led to the conclusionthat in Tibet, Cretaceous can be divided into three parts. Cretaceousbivalves thrived in two periods. In middle Cretaceous (Aptian--Turonian),the Gandese--Nianqing--Tanggula province was characterised by the firstreef--building of rudists and the flourishing of Ostreacea and Trigoniidae,whereas the Himalayan province--Inoceramidae, Trigoniidae andPectinacea. In late Cretaceous(Conician--Maastrichtian), the Himalayanprovincce was characterised by the second reef--building of rudists andthe abundance of Ostreacea, Inoceramidae, but in most part of Gandese-Nianging Tanggula province few bivalves were found. The plate--tectonicimplications of these phenomena are also discussed in this paper.
