【摘要】 造山带和盆地成因是当前地学研究的两个热点。本文第一部分简述了多种主要造山理论和成盆学说;其中挤压造山说与拉张成盆论在众多学说中仍占主导地位。一般都认为造山带和盆地形成于不同的地球动力学环境。第二部分结合我国地质实际,提出了造山和成盆作用形成于统一的动力学环境,即他们的形成是由于挤压后效——拉张-均衡造山、成盆。更多还原

【Abstract】 The origins of orogenic belts and basins are two hot topics of current geoscience research. The first part of this paper briefly introduces various main concepts of orogeny and basin formation. Among these concepts, those of the formation of mountains by compression and the formation of basins by extension are dominant position. It has been generally considered that orogenic belts and basins are formed by different geodynamic mechanisms. In light of China’s actual geological conditions it puts foreward that mountain ranges and basins are formed by a unified geodynamic mechanism, i. e. their formation is due to the after-effect of compression-extension-isostat-ic orogeny and basining.更多还原
