1:250000 geological mapping has further revealed the mysteries of the tectonics of the Qinghai-Tibet Plateau. The Altun Mountains are not of the Tarim massif, but a part of the Kunlun-Qilian-Qinling orogenic system; the Altun fault is a large transform fault; the Muztag-Maqên suture zone and Jinshajiang suture zone are both Variscan ones; the Songpan-Garzê area in the Triassic was a huge turbidite basin on the southern margin of Laurasia; the Gangdise belt underwent the important Indosinian orogenic movement; an ocean basin that persisted from the Paleozoic to Triassic did not exist, i.e. the so-called Paleo-Tethys or permanent Tethys was not in existence in the Qinghai-Tibet Plateau. In the Paleozoic, most parts of China, including the Sino-Korean, Yangtze and Tarim massifs and the Qinghai-Tibet Plateau, were located in south of the main ocean basin—the Central Asian-Mongolian sea way—of the Paleo-Asia ocean, belonging to the northern margin of Gondwana. The Yarlung Zangbo and Bangong -Nujiang belts were twins in the Tethyan Ocean, which began to develop into two ocean rift belts in the Triassic. The Tethyan Ocean with the Yarlung Zangbo belt as the main ocean basin belt began to be subducted in the Late Triassic and experienced a process of pulsatory plate convergence orogeny including the Indosinian, Yanshanian and Himalayan stages.

1：25万地质填图进一步揭开了青藏高原地区大地构造的奥秘：阿尔金山是昆仑，祁连-秦岭造山系的一部分；阿尔金断裂确是一条大型转换断层；木孜塔格-玛沁缝合带和金沙江缝合带均是华力西缝合带；松潘甘孜三叠系沉积盆地是劳亚大陆南部边缘的浊积岩盆地；冈底斯带曾经历了重要的印支造山运动；不存在从古生代延续到三叠纪的大洋盆地，即不存在所谓古特提斯或永久特提斯；古生代时期，在青藏高原地区亦不存在具古生物，古地理分隔意义的大洋盆地，当时，包括中朝，扬子，塔里木以及青藏高原地区在内的中国大部分均位于古亚洲洋主洋盆——中亚-蒙古带之南，属冈瓦纳大陆结构复杂的北部边缘；雅鲁藏布江和班公湖-怒江带是特提斯洋中的孪生姊妹，它们均是从三叠纪起就发展成大洋裂谷带的；以雅鲁藏布江带为主洋盆带的特提斯洋，从三叠纪晚期开始消减，经历了印支，燕山，喜马拉雅3个阶段脉动式板块汇聚造山过程。

Results show that obduction and napper were main tectonic movements in late Indosinian-early Yanshan period of Lower Yangtze Region, and most areas were elevated and denudated. Source rocks of lower-Paleozoic in some areas did not deep bury renewedly, and remain the Indosinian thermal evolution state. Therefore the high maturity sapropelic organic matter of lower-Paleozoic has still possessed hydrocarbon generation potential.

研究结果表明，晚印支-早燕山期，下扬子区的构造运动以逆冲推覆为主，大部分地区遭到抬升剥蚀，部分地区下古生界烃源岩抬升后晚期没有再度深埋，保留了印支期的热演化状况，因此下古生界高成熟腐泥型烃源岩现今仍具有一定的生烃潜力。

And whether is it necessary to redefine the geotectonic pattern in southern China? In 1993, the authors discovered firstly the late Paleozoic radiolarian silicalite in the "Shuangqiaoshan Group", which, as we know, is a block within the ophiolitic mélange. In 1996, the authors discovered again the late Paleozoic fossils in the other rocks of "Shuangqiaoshan Group" and "Zhitang Formation" of Lower Sinian Series in the ophiolitic mélange. At the same time, the authors discovered firstly the early Paleozoic chitinozoa fossils.

Based on the settings and geological and geochemical characteristics of granitoids of different orogenic belts (exemplified by orogenic granitoids in Altay, East Kunlun, Yanshan in North China, Northeast China and Nanling in South China), the relationships between granitoids and continental crustal growth are discussed, and five modes of continental crustal growth in the continent of China are proposed;they are as follows:(1)the Altay mode of continental growth is that the material and heat of the Paleozoic convertive mantle formed on the background of the Paleo-Asian Ocean were input into the Paleozoic continent and mixed with the materials of the upper crust;(2) the East Kunlun mode is that the basement of the Proterozoic orogenic belt was reworked by the heat input and materials of the Paleozoic-early Mesozoic convective mantle formed on the background of TTG continental crust of the Proterozoic orogenic belt;(3) the Northeast China style is that the Phanerozoic continental crust was reworked by the heat input and materials from the convective mantle formed on the background of the Yanshanian Central Asian orogenic belt;(4) the Yanshan mode is that the Archean basement was reworked by the heat input and materials from the Yanshanian convective mantle;and (5) the Nanling mode is that in South China what was input by the Yanshanian convective mantle into the continent was mainly heat and subordinately materials and the crustal material recycle was the dominant mode for the continental growth (showing zero continental growth).

根据不同造山带花岗岩的形成背景，地质地球化学特征差异，以阿尔泰，东昆仑，华北燕山，东北和南岭造山带花岗岩为例讨论花岗岩与大陆地壳生长的关系，区分出中国大陆的5种大陆地壳生长方式：阿尔泰式是古亚洲洋背景上形成的古生代对流地幔物质，热输入和上地壳混合为主的方式；东昆仑式是元古代造山带TTG陆壳背景基础上古生代—早中生代对流地幔物质和热输入，改造元古宙造山带基底的方式；东北式是燕山期中亚造山带背景上对流地幔物质和热输入改造显生宙陆壳的生长方式；燕山式是燕山期对流地幔物质和热输入改造太古宙基底的方式；南岭式燕山期对流地幔输入大陆的是以热为主，物质为辅，大陆地壳生长是以陆壳物质再循环为主的生长方式。
