摘要:
提要:本文以区域地质、矿产地质为基础,与地球物理和岩石圈深部地质的研究成果相结合,对中国东南陆区的地块、造山带、古板块结合带、隆起带、坳陷带和断陷盆地的地壳厚度变化与物质结构、莫霍面形态、岩石圈地幔的厚度变化与结构进行了研究与构造区划。论述了燕山期陆内造山与喜马拉雅期大陆伸展及其导致的岩石圈物质结构调整作用,建立了隆坳构造分异与壳幔物质结构调整模式,探讨了本区地壳减薄的深部地质过程,分析了燕山期陆内造山的动力机制以及大规模成矿作用与岩石圈物质结构构造的相关关系。

Abstract:
Abstract:Based on regional geology, mineral geology and geophysics in combination with researches on the lithosphere and the earth's interior, the authors studied the variation of the crustal thickness of such geological bodies as block, orogeny, paleoplate suture zone (conjunction zone), uplift zone, depression belt and fault basin as well as that of the mass structure, Moho form and the lithospheric mantle in Southeast China continental area, carried out structural regionalism, discussed in detail the Yanshanian intracontinental orogenesis and the Himalayan continental extension as well as the process leading to the adjustment of lithospheric mass structure, and formulated an adjustment model for uplift and depression structural differentiation and crust-mantle mass structure. In addition, the thinning process of the crust at depth was investigated, and the dynamic mechanism of Yanshanian intracontinental orogeny as well as the large-scale ore-forming process in relation to the lithospheric mass structure was analyzed.
Key words:  lithosphere  mass structure  intracontinental orogeny  continental extension  dynamic mechanism  ore-forming process
