Simultaneously with the emergence of the continental drift hypothesis, Li Siguang actively approached and dealt with the problem of continental crust horizontal movement and, in combination with the reality of China's mainland, developed the theory of intracontinental collision deformation, i.e., the geomechanic theory and method that included the global continental tectonic system.
中文摘要:本文简要地介绍了魏格纳大陆漂移说的主要内容及其提出的依据;论述了在大陆漂移说的基础上,由于海洋地质地球物理调查发现了大洋中脊、洋底扩张,解释了大陆张裂的机制,并建立了全球板块构造理论,形成现代地学思想的革命;李四光在大陆漂移说提出的同时已在积极地探讨和论述大陆地壳水平运动问题,并结合中国大陆实际,发展了陆内碰撞变形理论,即包括全球大陆构造体系在内的地质力学理论和方法。

India's defining geological processes commenced seventy-five million years ago, when the Indian subcontinent, then part of the southern supercontinent Gondwana , began a northeastwards drift —lasting fifty million years—across the then unformed Indian Ocean .
印度次大陆的地质构造的形成在七千五百五年前就开始了,随后南部的冈瓦纳大陆沿东北方向漂移,这个地质构造过程持续长达五千万年,跨过未形成的印度洋,抵达欧亚板块并和欧亚板块发生碰撞,最后升起形成这个星球上最高的喜玛拉雅山脉,该山脉目前位于印度的北部和东北部。

Dated from Proterozoic to Mesozoic, they have poly-circle characteristics, found from one tectonic circle to another, which is very rare in the worldwide orogens. This reveals that the orogen and stable area of the world, the mantle and crust states of the Proterozoic and Phanerozoic are different in tectonic evolvement and dynamic process and that the rapakivi granite of the Qinling-Kunlun is a kind of orogenic granite different from the stable area of the Proterozoic.

The material for formation of the granitoids isderived from mixing sources of crust and mantle, with decreasing in crust-derived componentsfrom early to late.5. The tectonic setting for formation of the Mesozoic granitoids in the region isdefined as a post-collisional setting. The occurrence of a small part of rocks with characteristics ofcollisional or anorogenic granitoids provides evidence for the continuous process oftransformation of tectonic regime from collisional through post-collisional to anorogenic.6. Themultiple cycles of mantle-derived magma underplating caused by the multiple stages oflithospheric thinning in the Mesozoic result in the partial melting of middle to lower crust orcrust-mantle syntexis to form magmas. The crystallization of these magmas emplacing afterfractionation is responsible for the formation of the Mesozoic granitoids in this region.
形成花岗岩类的成岩物质来自壳幔混源。5、河南省西部地区中生代花岗岩类成岩构造环境为碰撞后环境,部分岩石具有碰撞期或非造山期花岗岩的某些特征,表明碰撞后阶段既是碰撞造山过程的延续,又是向非造山环境的构造转换时期,因而其岩浆活动在一定程度上仍然继承了碰撞前消减时期和碰撞时期已经活化的岩浆源区性质。6、研究表明,区内中生代多阶段的岩石圈减薄作用引发多旋回的幔源岩浆底侵以及中下地壳的部分熔融或壳幔同熔,由此形成的岩浆经分异演化后侵位可以形成区内的中生代花岗岩类。

In addition, the features of elemental geochemistry of all samples suggest that (1) the EarlyTriassic andesitic rocks, characterized by characteristic natures of island arc volcanics, likely erupted in the subduction setting; that (2) the generation of LateTriassic rhyolites with an affinity of Alike granite and synchronously main body granites in the Lincang batholith displaying similar geochemical features, is closely related with the postcollision or latecollision setting; that (3) although the LateTriassic basic rocks partly show island arc volcanics such as highAl contents and NbTa depletion, some of them possessing highMg contents and mostly having traceelement ratios similar to intraplate basalt, which indicates that they erupted in the postcollision rift environment.
元素地球化学特征表明,早三叠世火山岩具有典型的岛弧火山岩的特征,暗示其很可能形成于俯冲的构造环境;中三叠世晚期的流纹岩与临沧花岗岩基主体具有非常相似的地球化学特征,结合其流纹岩具有A型花岗岩属性,表明该区中三叠世火成岩形成于碰撞后的构造背景;而晚三叠世基性火山岩虽然在地球化学特征上显示出与岛弧火山岩相似的高铝和NbTa的亏损,但其中部分火山岩具有高镁和板内玄武岩的微量元素比值特征,说明这些火山岩可能形成于碰撞后裂谷环境。
