對鄔郁盆地嘎扎村組火山巖剖面的年代學研究表明,該區后碰撞期火山巖的~ ( 40 ) ar - ~ ( 39 ) ar年齡為12 ? 14ma ,侵入其中的花崗巖脈的~ ( 40 ) ar - ~ ( 39 ) ar年齡為10 . 84ma ,與岡底斯西段前人研究資料對比,認為岡底斯帶后碰撞火山巖時代有自西向東逐漸年輕的趨勢。This formation is dominated by a set of sandstone - mudstone dark clastic rock series which belongs to marginal marine deposit at the end of the gondwana carboniferous - permian glacier period
該組主要為一套砂巖泥巖的暗色碎屑巖系,屬岡瓦納石炭二疊紀冰川末期的邊緣海沉積。It seems that submarine magmatism and hydrothermal activity provided abundant ore - forming material for partly strata of mogaganri and yanshiping formations during the extension of bangongcuo - nujian marginal sea in early - middle jurassic. therefore parts of jurassic mogaganri and yanshiping formations became original source of ore - forming material. in later early jurassic, the collision and collage between qiangtang block and nianqing - tanggula block made favorable conditions in geological structure, magma and ore - forming fluids for the formation of gold deposits
在早-中侏羅世班公錯?怒江邊緣海擴張過程中,海底巖漿及其熱液作用,為侏羅系木嘎崗日群和雁石坪群部分層位提供了大量的礦源,使其成為初始礦源層;早白堊世晚期,羌塘地塊和岡底斯?念青唐古拉地塊碰撞拼貼,造成了有利的構造條件、巖漿條件、成礦流體條件,形成礦床。The developments in stratigraphy are involved in the division of the surveyed area into the gangdise - nyainqentanglha - tengchong stratigraphic province and bangong - nujiang suture zone ; subdivision of the bangong - nujiang suture zone into the nyainrong microcontinent and jueweng - yulashan - xagquka m lange zone ; redivision of the nyainrong microcontinent and lagongtang formation ; re - establishment of the gajia formation ; reconstruction of the guoqu group ; disintegration of the muggar kangri group into three group complexes
摘要地層方面,將測區地層劃分為岡底斯騰沖地層區和班公錯怒江結合帶,班公湖怒江結合帶中又劃分出聶榮微地塊和覺翁余拉山下秋卡混雜帶兩個小區;按變質巖調查方法解體了聶榮地塊;對原大面積分佈的拉貢塘組進行了有效的解體;新建立嘎加組;恢復了郭曲群;將木嘎崗日巖群解體出3個巖組。During this evolution, seven second - order tectonic units were formed ; from north to south are the mingqianri cretaceous residual sea basin, the arsuo tectonic melange zone, the taricuo - wenbu yenshan magmatic arc belt, the cuoqin - bangduo late paleozoic composite back - arc basin, the jiangrang - geerdi faulted uplift, the gangdise - chazi himalayan magmatic arc belt, and the xigaze - anba fore - arc basin. these units comprise important parts of a poly - arc - basin system and exhibit evolutional features of mesozoic to cenozoic arc - basin systems. mosaic pattern of these tectonic units delineates the lithosphere coupling processes of the gangdise tectonic belt under mechanisms such as back - arc basin attenuation and arc - continent collision
自中新生代以來,岡底斯構造帶經歷了洋殼俯沖、弧陸碰撞、陸內俯沖-碰撞、走滑和塊段隆升的多階段構造演化歷程,形成了由北向南七個二級構造單元,即岷千日白堊紀殘余海盆、阿索構造混雜巖帶、它日錯?文部燕山期巖漿弧帶、措勤?幫多晚古生代復合弧后盆地、江讓?格爾耿斷隆、岡底斯?查孜喜馬拉雅期巖漿弧帶、日喀則?安巴弧前盆地。Mesozoic to cenozoic magmatic activities in the cuoqin area of the gangdise belt were intensive and display temporal cycling and spatial zoning
