Their structural environment is mainly volcanic arc 其構(gòu)造環(huán)境主要為火山弧地區(qū)。
Analysis of the structural environment of the izmit earthquake 伊茲米特地震發(fā)生的構(gòu)造環(huán)境分析
Judging for characterstics of geochemical and structural environment of several caledonian granitoids in northeast guangxi 桂東北地區(qū)幾個(gè)加里東期花崗巖體的地球化學(xué)特征及其構(gòu)造環(huán)境判別
Aad , it is due to the complicated geological structural environment resulted from the separation , merging , collision of plates which consists of land nucleus in geologic history , and it results in the multiple cyclic state of china s land nucleus development 而造成中國油氣地質(zhì)條件的復(fù)雜性的地質(zhì)構(gòu)造環(huán)境,則是在地史中各陸核組成的板塊之間分合和碰撞,使得中國陸核的發(fā)展呈多旋回狀態(tài)。
At first the authors explain the structural environment of earthquake in china , by giving an example of the institutes of epicenter of earthquake in china , from january , 1989 to december , 1998 , it shows the recent activity characteritic and districts division of earthquake in china . secondly they give a prediction by explaining stages about the earthquake activity in the past 100 years in china 首先對(duì)中國地震構(gòu)造環(huán)境作了分析,并以1989年1月至1998年12月中國地震震中分布為例說明中國近期地震活動(dòng)特征且對(duì)中國近期進(jìn)行地震分區(qū).最后,試圖通過對(duì)中國近100年地震活動(dòng)分期分析,作出相應(yīng)的中長期預(yù)測
The paper gives a mechanical and history analysis on the characteristic of laojunshan metamorphic core complex in southeastern yunnan and its structural environment , and considers that metamorphic core complex is actually a nuclear column of a vortex structure , which was caused by the wenshan ? malipo strike - slip fault 通過滇東南老君山變質(zhì)核雜巖特征及周圍構(gòu)造環(huán)境的力學(xué)分析及歷史分析認(rèn)為,該變質(zhì)核雜巖實(shí)質(zhì)上是旋扭構(gòu)造的砥柱,而旋扭構(gòu)造又源于文山?麻栗坡斷裂的走滑運(yùn)動(dòng),拆離伸展構(gòu)造晚于旋扭構(gòu)造。
