Through the experiments of three kinds of models mentioned above, the structural deformations of "outflow-extension","strike-slip-extension" and "uplifting-extension" are studied and some viewpoints involving that the plastic flow in the lower lithosphere controls the extensional structures are stated as follows:(1) Regional extensional structure does not result from the direct extension along the upper crust, but from the plastic flow in the lower lithosphere and its dragging and stretching the upper crust;(2) Deformation of continental extensional structure resulted from the active uplifting of mantle is conditional that the significant extension occurs only in the models with free- or outflow-boundary condition on both sides, whereas the passive uplining of mantle exists widely, because it is an inevitable consequence of the efiect of thermo-gravity isostasy;(3) Strike-slip shearing in the lower ductile lithosphere, including site-restricted and site-unrestricted shearing, can result in various types of extension structures;(4) The"graben-horst"type extensional structures can be formed in difierent mechanisms, including outnow-extension, shear-extension, uplifting-extension and their synthetical action.

通过上述三种模型的模拟试验，比较系统地研究了"泄流-伸展"、"走滑-伸展"和"上隆-伸展"等构造变形，提出岩石圈下层塑性流动控制了各种伸展构造变形的观点，主要包括以下几方面：(1)区域性伸展构造不是上层直接受到拉伸，主要是下层流动牵引上层伸展；(2)地幔主动上隆引起大陆伸展构造变形是有条件的，需要侧边伸展或不受约束的边界条件，而被动上隆广泛存在于地壳断裂或减薄部位，是热和重力均衡的必然结果；(3)下层塑性流动中的走滑剪切，包括限位剪切或非限位剪切，可以引起不同型式的伸展构造；(4)总结了"堑-垒"型伸展构造的多种成因机制，包括泄流、走滑、上隆及综合作用均可形成"堑-垒"构造，但组合形式不尽相同。

New data of structural styles and geochronometry in the Dulong-Song Chay metamorphic dome indicate at least two epoches of major extensional tectonics: the D, deformation of the rising and exhumation of the dome occurred at 237-228 Ma; and the D2 deformation overprinted and re-deformed on the dome at 86-78 Ma. Of them, the D, deformation shows a consistent forming time, extensional direction and tectonic regime amongst the Dulong-Song Chay dome, South China block and the north margin of the South China Sea basin.

对位于华南地块西南缘的都龙－Song Chay变质穹隆体的研究表明，在中生代至新生代时期，至少经历了2期重要的伸展构造：D1期(237~228 Ma)穹隆的隆升与表露阶段，代表了印支期造山作用前的伸展构造；D2期(86~78 Ma)叠加和改造阶段，并有可能始于176~146 Ma，致使穹隆进一步隆升和表露。D2期构造在发育时间、伸展方向及变形方式等上既与华南地块同时期区域伸展构造特征相一致，也与南海盆地北缘早期扩张特征相一致。

In working area and its adjacent area, the forming tectonic setting of Indosinian intrusion was that orogenic belt pressed strongly, intracontinental subduction; that of early Yanshan movement epoch was the stress field transferred from compression to extension meanwhile the incrassate crust of orogenic zone turned to extensional collapse; and that of early Cretaceous volcanics was that the area structure extensional collapse further more during the post period of orogenic phase.

研究区及邻区印支期侵入岩形成于造山带强烈挤压陆内俯冲的构造环境；燕山早期侵入岩形成于由挤压转向拉伸、造山带的增厚陆壳开始发生伸展垮塌的构造环境；早白垩世火山岩形成于造山期后进一步发生伸展垮塌的区域构造环境。
