Under the guidance of theories of sedimentology, petroleum geology and sequence stratigraphy, and through the comprehensive analysis of outcropsrock, cores, well logs and testing outcomes of rock gas, this paper studies the depositional systems of neopaleozoic and the character of aeration zone in tabamiao area of ordos basin. the result indicates that the object layers are divided into two depositional systems, the barrier seacoast depositional systems are recognized on upper carboniferous taiyuan phase with tidal flat, lagoon and barrier bar sedimentary deposit
本文根據沉積學、石油地質學和層序地層學理論，綜合利用地表露頭、鉆井巖芯、測井曲線資料和試氣成果資料，對鄂爾多斯盆地塔巴廟區塊晚古生代沉積體系及含氣層特徵進行了研究。結果表明，研究區內目的層段可以劃分為2個沉積體系： （ 1 ）上石炭統太原期為有障壁海岸沉積體系，發育潮坪?瀉湖?障壁砂壩沉積。2 both the hanging wall and the footwail rock of ore bodies are garnet biotite schist, protoliths are alkaline volcanic rocks ( tracyh andesite ). according to characteristics of trace elements assemblages and the setting of tectonics, these alkaline volcanic rocks were derived from the lower degree melting of metasomatic and enriched mantle ( eml ) in the initial stage of middle proterozoic epoch. they strongly enriched in large ion lithophile elements ( lile ), such as ba
2 、礦體頂、底板圍巖（石榴石黑雲母片巖、鈉長黑雲母片巖等）的原巖為堿性火山巖（粗面安山巖） ，相對富集大離子親石元素ba 、 cs 、 rb 、 k 、 lree及貧zr 、 sr 、 ti 、 hf 、 hree ，為早元古代末期-中元古代早期交代富集地幔低程度部分熔融所形成的堿性火山巖。The pges abundance patterns of residual mantle rock with a peleo - subduction background is characterized by pd, pt depletion and ir, ru relatively enrichment, while the basalt and basic dyke by the processing of partial melt in the same background take an opposite feature of pd, pt enrichment and ir, ru depletion. the existence of fluid in the subduction zone increases the degree of partial melt on the one hand, and on the other, activates the activity of pd, pt compare to ir, ru, and thus reduces the pd ir and pt ru in residual mantle rock. the pges patterns for basalt and basic dyke from two carboniferous volcano zones to south qoltag and north turpan - hami basin, xinjing uigur autonomous region, take a shape of gentle positive inclined curve with lower pt and pd differentiation and lower pges. all these features are obviously different from that of basic dyke and basalt from typical ophiolite and therefore the author believe that their fluid - rich paleo - subduction zone environment can be ruled out
古俯沖帶背景下的殘餘地幔巖的pges配分以pd ， pt明顯虧損和ir ， ru相對富集為特徵，而部分熔融產物的玄武巖和基性巖脈則呈現相反的ir ， ru明顯虧損和pd ， pt相對富集特徵。俯沖帶中流體的參與一方面增加了部分熔融程度，有利於pd ， pt從原始地幔進入熔融相另一方面，流體的作用使得pd ， pt相對于ir ， ru遷移活動性效率提高，造成地幔巖中Mound form, ice erosion rock basin and broken to fall into basin spread all over at plateau, china most heavy zh zh body traces, namely " daocheng ancient to ice cap ". .
丘狀冰蝕巖盆和斷陷盆地遍佈於高原上，是中國最大的古冰體遺跡，即"稻城古冰帽" 。 。 。The unconformability between the loess landform of shaanbei loess plateau and its bedrock shape was pointed out first after the full demonstration. the top of loess formation of the south part in shaanbei is flat which likes " platform ", the shape of the bedrock is rolling that likes ridge, and the bedrock bended to fold. the top of loess formation of the mid - part in shaanbei is rolling, but the shape of the bedrock below begins to get flat, the top of loess formation of the north part in shaanbei, loess mao district, is much more rolling among them, however, its shape of the bedrock below is the flattest relatively likes the platform shape of loess formation in south
具體地講，陜北高原南部的洛） 11黃土源，黃上層頂部相對平坦，地貌類型以黃土源為主格調，而其下伏基巖地層詔皺相對發育，古地勢起伏相對較大：陜北高原中部的延安一安塞黃土梁狀（為主）丘陵溝壑區，黃土層頂部起伏相對增大，地貌類型以黃土梁為主格調，而其下伏基巖地層槽皺程度趨弱，地層較平緩，古地勢起伏相對降低；陜北高原北部的綏德一子洲黃土赤狀（為主）丘陵溝壑區，黃土層頂部起伏度相對最大，地貌類型以黃上赤為主格調，而其下伏基底地層以平緩為特徵，古地勢起伏強度亦相對較低。Ascertaining the paleocurrent direction of the mesozoic basin and reconstructing the paleogeography ; ( 4 ). deciding the material components and original structure sequences of the basin provenance, and coupling relationship between the sediments of the basin and geologic units of the provenance ; ( 6 ). establishing the mesozoic tectonic evolution history of the dabie orogenic belt and discussing the collisional mechanism of the belt
