Ali Dongpo Ultrabasic Rocks Deep Reflection Seismic Data Interpretation Research

With the development of modern industry,the efforts to develop resources in a constantly increasing,while demand for all kinds of minerals is growing.Chromite is an important strategic m aterial,which has a hard,wear-resistant,high tem perature resistance,corrosion resistance,etc.,it is very widely used in industrial production,which often output in ultrabasic rocks into.Dongpo ultrabasic ro cks located in the Indian plate and Eurasian plate collision suture zone-the western part of the Yarlung Zangbo suture zone,m ineralization has ve ry good prospects,and China' s largest chromite bed-Luobusha chrom ite bed and Dongpo ultrabasic rocks into the Yarlung Zangbo suture zone with the Department.Through deep reflection seismic sections of a 31km-long geological phenom ena on the de pth and structural features were underground rock exploration and explanati on.Ultrabasic rocks exhibit wider at the "basin" feature,rock width of about 21.25 k m,with increasing depth,width becom es smaller rock,rock maximum depth of about 10 km,which an explanation of the results of magnetotelluric past are in good agreement.Meanwhile,deep reflection seism ic geophysical exploration as an important method,is recognized as geologists probe the fine structure of lithosphere,subduction,one of deep geological problem s Nappe housing as the m ost effective technical means.As the Earth' s youngest continent-continent collision resulting suture,Yarlung Zangbo suture zone has always been one of the hot areas to acad emic research.The su ture zone in C hina stretches more than 1500 km,the m ain east-west trend ing suture zone accom panied by sporadic rock outcrops of ophiolites.Howe ver,geologists study the su ture disruption and m ore concentrated in the eastern,western part of the research is very scarce.This paper explains the use of seism ic sections in the western part of the Yarlung Zangbo suture zone is just one of deep reflection seismic profiles,use this valuable information to the western part of deep tectonic suture zone detection and interpretation is carried out scientific significance and value.Through se ismic reflection characteristics of the study area where the regional st ructure before and previo us to the Y arlung Zangbo suture zone,the eas tern section of the resu lts were analyzed,the thesis in d eep seismic reflection profiles drawn three fract ure.Where the deepest depth of about 38 ~ 50 km,presumably dominated Himalayan Thrust(MHT)suture zone in the weste rn part of the signs.Fracture at a depth of about 20 ~ 32 km is the interface of ophiolite slab.The explanation for the deep structur e in the west of the Yarlung Zangbo suture made initial discussion s conducive to constru ct the entire suture to conduct a comprehensive analysis to study m ore conducive to raising the issue of the Indian plate and Eurasian plate collision and the Tibetan Plateau.
