Countermesure on marine fishing gears in sorth china sea region 南海區(qū)海洋漁具管理對策
The corporation has set up close business relations with korea . japan . u . s . a . eec . sorth east asia etc . countries and regions . during the long time co - operation , it has been praised by the customers both in and ort of the country for its good reputation , excellent service and sincerity . its economical benefit and the values of trade are increasing constantly 公司以良好的信譽(yù),優(yōu)質(zhì)的服務(wù),誠摯的合作贏得國內(nèi)外客戶的好評,先后與韓國、日本、美國、歐共體、東南亞等國家和地區(qū)建立了貿(mào)易關(guān)系,貿(mào)易額和經(jīng)濟(jì)效益都穩(wěn)步增長。
Besides , the sedimentary facies of upper ganchaigou and lower ganchaigou formation were also mapped in supersequences which are the main target strata for exploration . the high resolution sequence stratigraphic framework showed the genetic relationship between the distributions of sedimentary facies and their tectonic settings . the near - source sedimentary systems such as subaqueous alluvial fan and lake - floor fan are often deposed in rise - hemicycles in the steep slope background in the north , the coarse lithology of fan - delta prograded from north to south in fall - hemicycles , and the braided stream facies are formed in the rise - hemicycles in gentle slope background in the south , braided stream facies prograded from sorth to north in the fall - hemicycles , but the lacustrine facies and salt lake facies developed in the middle part of the area 詳細(xì)的沉積相研究發(fā)現(xiàn),紅獅地區(qū)第三系發(fā)育有沖積扇、水下沖積扇、河流、三角洲、扇三角洲、湖泊和湖底扇7種主要沉積相類型,并對作為區(qū)內(nèi)主要勘探目的層系的下干柴溝組和上干柴溝組進(jìn)行了以超層序?yàn)閱挝坏某练e相平面編圖,以較高的時(shí)間分辨率揭示了區(qū)內(nèi)沉積相帶的平面展布及其在不同構(gòu)造背景中的分布規(guī)律,比如在北部的凹陷陡坡背景下,上升半旋回低水位期通常發(fā)育有水下扇、湖底扇等陡岸近源特征的沉積體系,下降半旋回高水位期,扇三角洲相粗碎屑巖由北向南進(jìn)積;在南部的凹陷緩坡背景下,上升半旋回主要發(fā)育辮狀河流相,下降半旋回辮狀河三角洲相由南向北進(jìn)積;而中部紅柳泉一獅子溝一帶則為湖泊相沉積和鹽類沉積。
