( 1 ) systematically gathering the data about large - scale and superlarge - scale deposits in the world and drawing up the map of global tectonics and metallogeny ; finding out the segmentation of circle - pacific ocean metallogenic belt and informing that the giant deposit clusters are the prominent feature of global metallogeny 本文在总结全球大规模成矿的地球动力学背景资料基础上,通过深入解剖和系统对比我国三江造山带南段、东秦岭造山带和兴蒙造山带中南部等典型造山带关键地区以陆内演化过程为核心的地球动力学演化历史及其成矿特征,重新认识了我国大陆印支?早燕山期的动力学演化过程及其成矿效应,建立了关于造山带陆内演化阶段主要过程中的大规模成矿模式。 |
| 8. | Yinggete - bagemaode metamorphic core complex belt with three - layer construction is put forward , which evolved from late jurassic to cretaceous . the extensional simple shear model of the chagan fault depression is established . the tectonic evolution and the dynamics character of chagan fault depression and its adjacent mesozoic - cenozoic basins are discussed : at the end of triassic continental orogeny increased crust thickness crust uplift and denudation were happened ; jurassic was a period of local partly extensional collapse of erogenic belt and cretaceous was a period of widely extensional collapse of postorogenic erogenic belt ; cenozoic was a period of the development of stable intracontinental depression with the character of long distant collision response and weaked compression flexure 讨论了查干凹陷及邻区中-新生代盆地构造演化及其地球动力学特征,三叠纪(印支期)为陆内造山作用与地壳增厚、隆升剥蚀阶段;侏罗纪(燕山早期)为造山后造山带的局部伸展垮塌阶段;白垩纪(燕山晚期)为造山期后大规模伸展垮塌作用与伸展盆地的发育阶段;新生代(喜山期)为远距离碰撞效应与弱挤压挠曲性质的稳定大陆内坳陷的发育阶段。 |
| 9. | A general survey of the formation , evolutionary histories of continental orogenic belts both in china and abroad reveals that orogenic belts have often undergone numerous and varied tectono - evolutionary stages , such as palaeocontinental break - up , ocean - land transition , continental matching - collision , intracontinental extension - basin - range coupling , and new tectonic uplift ( intracontinental orogeny ) , which are respectively accompanied by characteristic volcano - magmatisms 纵观我国以至全球的大陆造山带形成、演化历史,一个造山带往往经历了古大陆裂解、洋陆转换、陆块拼合碰撞、陆内伸展盆山耦合和新构造隆升(陆内造山)等众多不同的构造演化阶段,这些不同的构造演化阶段和不同的构造环境均有特定火山岩浆作用与之相伴。 |
