  1. 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

    詳細的沉積相研究發現,紅獅地區第三系發育有沖積扇、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,並對作為區內主要勘探目的層系的下乾柴溝組和上乾柴溝組進行了以超層序為單位的沉積相平面編圖,以較高的時間解析度揭示了區內沉積相帶的平面展布及其在不同構造背景中的分佈規律,比如在北部的凹陷陡坡背景下,上升半旋迴低水位期通常發育有水下扇、湖底扇等陡岸近源特徵的沉積體系,下降半旋迴高水位期,扇三角洲相粗碎屑巖由北向南進積;在南部的凹陷緩坡背景下,上升半旋迴主要發育辮狀河流相,下降半旋迴辮狀河三角洲相由南向北進積;而中部紅柳泉一獅子溝一帶則為湖泊相沉積和鹽類沉積。
  2. The ore - bearing fluid of dabaoshan deposit was relate to magmatic thermal dynamic process and formed hydrothermal sedimentary polymetallic deposit at seafloor. the ore - bearing fluid of fankou was relate to circulation hydrothermal fluid in deep formation and formed pb - zn - ag - hg polymetallic middle - lower temperature sedimentary deposit by sea - floor thermal spring overflowing

    大寶山型流體與巖漿熱動力作用有關,形成海底火山熱液沉積多金屬礦床;凡口型流體與深部建造的循環熱液有關,形成中低溫海底熱泉噴溢沉積鉛鋅銀汞礦床;紅巖型流體與盆地成巖壓實水有關,形成低溫單一黃鐵礦礦床。
  3. The sedimentary facies of the jurassic penglaizhen formation in the studied area can be described as follows : from the edge of the basin, the source of deposition, to the center of the sedimentation are alluvial fan facies fluvial facies fan delta facies delta facies lake facies and lake floor fan facies in turn

    研究區侏羅世蓬萊鎮期沉積盆地的沉積相類型分佈,從盆緣近物源區至盆地沉降-沉積中心區依次為沖積扇、河流相、扇三角洲相、河控三角洲相、湖泊相和湖底扇相等沉積體系。
  4. Phosphate deposits are distributed along the margin, platform and basin in the west yangtze area. the analysis methods include the paleogeography, petrology, organic geochemistry, geochemistry. the conclusions are drawn that the source of phosphate deposits distributed along the margin originate from the weathering production of continent, while phosphate deposits along the platform and basin gain phosphorus through hot spring on the buttom of the sea floor, which is brought to the sedimentary environment by rising sea - fluid, then accumulated by the organism and microorganism, meanwhile, basin phosphorite keep relatively higher organic carbon content

    認為早寒武世早期古陸遭受風化,被剝蝕下來的產物成為潮坪型磷塊巖的主要磷質來源,在碳酸鹽巖臺地發生的熱點活動和上升洋流從盆底深部帶來的磷質,共同作為臺地型磷塊巖的磷源,盆地型磷塊巖的磷質同樣是由熱點活動和上升流攜帶至缺氧的沉積環境中,通過藻類或微生物的富集作用成巖,並保留了較高的有機碳含量。
