yanshiping meaning in Chinese
雁石坪
Examples
- Although many achievements were obtained during recent years , researching areas and contents are still limited and uncompleted and there is a debate about jurassic stratigraphic framework and sedimentary environments in yanshiping area and its southern places . during early jurassic the palaeo - oceanographical changes was an event influencing global geologic evolution
随着近年来石油地质调查和区域地质的开展，羌塘盆地侏罗系地层研究取得了长足的进展，但从研究地区和研究内容都是一些轮廓性的认识，对一些关键地质问题尚缺乏深入的了解。 - Through the analysis of the stratigraphy and sedimentary facies of the research areas , the description model between the stratigraphic framework and deposite environment can be set up firstly by the transition from the " three horizons sandstone with two intercalated limestone horizons ' mn yanshiping area to shale and marl in amdo - zigetang co , and to oil shale in bilong co , then by the transition of the shallow water platform facies to the deep water continental shelf , slope , and to the deep water basin
通过对研究区地层和沉积相分析，建立起一个从北向南由雁石坪地层类型“三砂夹两灰”过渡为安多?兹格塘错地层类型泥页岩、泥灰岩，最后到比洛错地层类型黑色油页岩，由浅水台地相过渡到深水陆棚、斜坡，最后到深水盆地相的地层格架与沉积环境解释模式。 - 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-中侏罗世班公错?怒江边缘海扩张过程中，海底岩浆及其热液作用，为侏罗系木嘎岗日群和雁石坪群部分层位提供了大量的矿源，使其成为初始矿源层；早白垩世晚期，羌塘地块和冈底斯?念青唐古拉地块碰撞拼贴，造成了有利的构造条件、岩浆条件、成矿流体条件，形成矿床。 - ( 2 ) based on the two important sections of yanshiping and yicangma , a study is conducted on the sedimentary features and facies of middle - upper jurassic series , it is suggested that quemo formation is river - delta facies deposit , buqu formation is chiefly carbonate ramp facies deposit , xiali formation is delta - tidal flat facies deposit , ? suowa formation is mixed shelf - lagoonal facies deposits and xueshan formation is river - delta facies deposit
( 2 )以雁石坪和依仓玛两条重点剖面为基础，开展了中?上侏罗统沉积特征、沉积相等方面研究，认为研究区雀莫错组为河流?三角洲相沉积，布曲组以碳酸盐缓坡相沉积为主，夏里组为三角洲?潮坪相沉积，索瓦组为混积陆棚?泻湖相沉积，雪山组为河流?三角洲相沉积。
