綜合研究區域成礦地質背景、鈾源、古氣候、水文地質、巖性巖相條件，認為范家屯九臺一帶的泉頭組及楊大城子一帶的青山口組發育辮狀河或三角洲前緣砂體，構成了鈾源供應充足的補徑排系統，具有有利的層間氧化帶形成條件，是本區地浸砂巖型鈾礦的有利成礦遠景區帶。The analyses of the sedimentary facies, rock geochemistry and reformation after the sedimentation from the upper cretaceous quantou formation to nenjiang formation indicate that the beneficial sand - bodies of the uranium deposit are mainly quantou formation ' s braided channel and qingshankou formation ' s delta sandstone types
摘要從上白堊統泉頭組嫩江組沉積相展布、巖石地球化學及沉積期后改造作用分析入手，闡明了研究區有利鈾成礦砂體主要為泉頭組的辮狀河與青山口組的三角洲砂體。And the delta genetic unit includes distributary channel, distributary bay, small lake of delta plain, swamp, distributary estuary bar, frontal delta mud and sandy density flow and so on. the fluvial system is composed of channel, channel side and flooding basin
其成因相包括分流河道、決口扇及決口河道、分流間灣、三角洲平原小型湖、沼澤、分流河口壩、前三角洲泥及砂質重力流等；該區河流體系由河道、河道邊部及泛濫盆地等沉積組合構成。3. it was rocky hills and relatively high in the yangtze river mouth area along changzhou, wuxi, changshu, kunshan and qingpu, which belonged to changzhou - kunshan zone according to holocene delimitation from the final stage of the liangzhu culture to the stage of the maqiao culture, due to the expansion of taihu basin and large water areas, maqioa cultural sites were concentrated on rocky hills and cheniersin the east of taihu to the west of shanghai
3 、蘇南常州、無錫、常熟、崑山和青浦一帶曾經是長江河口地區的基巖山地，在全新統地層分區上屬于常州一崑山區，是古地面地勢相對較高的地方。良渚文化末期至馬橋文化期，為太湖湖盆體系擴大時期，水域較大，所以馬橋文化遺址集中於太湖東部與上海西部地勢較高的基巖山地和砂堤之上。Based on the direction of sources and the ratios of sandstone to formation of sedimentary rocks, together with the sedimentary structures and textures, paleocurrent direction and the characteristics of paleontology, etc., the planimetric maps of sedimentary facies of each stages in the studied area are compiled in order to recognized the extension of dominant facies and the evlotionary history of sedimentary environment, hi the stage of benxi and taiyuan, lagoon - tidal flat sediments are widespread in the area, and the deposits of estuary, lagoon and small delta in the northwest margin of ordos
