与地洼学说相关的几个问题

ON PROBLEMS RELATED TO DIWA THEORY

强调了陆内地台活化造山,是地洼学说即活化构造理论的核心概念。并从板块构造“地学革命”对经典地槽造山成因论的否定;从近廿年板块构造研究华南大地构造取得突破经典板块碰撞造山模式,提出了板内弧后造山新模式的研究实例;以及从活化构造理论与多岛海板内变形理论的对比等几方面的阐明,指出陆内活化造山区,作为地台区、陆缘造山带之外的第三种大地构造类型,其自主创新的意义和作用至今并未改变。强调了地洼学说或活化构造理论与板块构造理论之间并不是对立和互相排斥,一分为二、取长补短,有利于推进中国大地构造的研究和理论的创新发展。

The intracontinental platform acti vization-orogenesis is the kernel i dea of the diwa theory(namely the activated tectonic theory).As a geosciences revolutionary,pl ate tectonic theory negnates the cla ssic geosyncline orogenesis.After the plate theory h as been involved into the geotectoni c study of South China for almost tweenty years,a new model of the intraplate b ack-arc orogeny breaks through the c lassic plate collision orogenic mod el,and comparison between the activated te ctonics and the multi-island-sea in traplate deformation is discussed.As the third geotectonic type besides the p latform region and marginal continental orogen,the intracontinental a ctivated orogenic region is existent and of in itiative.The relationship between the diwa theory or activated tectoni c theory and the plate theory is not oppose or e xclusive,but to learn from each other to make up deficiencies.Only thus c an the geotectonic theories of China be innovated,refreshed and developed.
