Tectonic framework and metallogenic - depositional environm ents in west kunlun mts 西昆侖山構(gòu)造格架與成礦堆積環(huán)境
Tectonic framework of north china block and its cratonization in the early precambrian 華北陸塊基底構(gòu)造格局及早期大陸克拉通化過程
Based on the study of tectonic framework and seismicity in the north china plain , main seismotectonic belts are determined , and earthquake capacities of the belts are evaluated 摘要本文分析了華北平原第四紀主要構(gòu)造格局和強震活動特點,劃分了主要強震構(gòu)造帶,并對其發(fā)震能力作了評價。
The general structure of the basin is marked by the tectonic framework of compressional ramp of the east kunlun mountains and the qilian mountains toward and subsidence of the central part of the basin 盆地的總體結(jié)構(gòu)表現(xiàn)為東昆侖山和祁連山相向向盆地擠壓對沖,盆地中部沉降的構(gòu)造格局。
At last they have being formed the tectonic framework , after breakup of the volcanic island arcs , subduction , decline and fall of the back - arc basins and arc - microcontinent and arc - arc collision had finished 經(jīng)過了長期而復雜的微大陸和火山弧的裂解、弧后盆地的消減衰亡及弧陸和弧弧碰撞等構(gòu)造演化,才最終形成今天所見到的這種構(gòu)造樣式。
