質堆積土
英文
cumulose-
Setenaly according to the analyses from selected profiles, we know that, it is cold and dry in this region during the early holocene when east asian winter monsoon ' s influence is obvious, so, it is a transition period from sand deposit to sandy soil deposit, when the layers become thinner gradually from north to south. during middle holocene, it is warm and humid, influenced evidently by east asian summer monsoon, so, it is an obivious pedogenesis, when there are generally well - developped holecene palaeosol ( so ) from north to south, and the pedogenesis in the south is better than that in the north, the soil is also thicker than that of the north. from late holocene to now, the climate changes to be dry and cold, but its changing scope is smaller than that of last glacial period
2 、就所選剖面分析來看，本區在全新世早期氣候回返，相對較寒冷乾燥，東亞冬季風影響較明顯，此時為沙層堆積向砂質土壤過渡，自北至南堆積的沙粒漸細；全新世中期氣候溫暖濕潤，東亞夏季風影響顯著，此時為明顯的成壤期，表現在自北至南普遍可見發育較好的黑壚土層，且南部的成壤作用比北部好，土壤的厚度也要大；全新世晚期至今，氣候向乾冷方向轉化，但變化幅度遠小於末次冰期。The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north
實驗結果表明：粘粒粉沙比值能很好地指示粉塵堆積物的次生粘化作用；磁化率和全鐵很好地指示生物風化成壤作用； sr和rb sr比值能很好的指示生物風化成壤作用和淋溶作用；總有機碳（ toc ）含量的高低，在一定程度上反應了土壤發育過程中氣候和植被狀況的變化，指示著成壤過程中腐殖質化的程度； caco3含量的變化，可以反映了黃土古土壤形成時的風化成壤作用的強弱程度，指示成壤過程中的淋溶作用和次生碳酸鹽化作用；並且各指標所指示的成壤環境和成壤強度存在明顯的區域差異，即渭河流域土壤的生物風化成壤作用、次生粘化作用和淋溶作用均表現出南部強于北部。Many research such as clay minerals, suspend in the sea, the grain size trend analysis of surface sediment, poc 6 cu and 8 c13 in bottom sediments etc. showed that : the yellow sea warm current divided the south yellow sea into two, the terrestrial material of modern sediment on the west shelf plain mainly came from the modem yellow river suspend carried by the alongshore current, and the sediment difference between the west and east side of yellow sea trough was represented by the sedimentation thickness in postglacial period, sedimentation stratum, and oxygen isotope record
粘土礦物、碳酸鹽、粗碎屑、海域懸浮體、表層沉積物粒度趨勢分析、 poc c ~ （ 13 ）及底質沉積物的c ~ （ 13 ）等多方面研究表明：以黃海暖流為主導，南黃海堆積陸架平原西側現代沉積物陸源物質主要源於黃海沿岸流攜帶的現代黃河懸移物質，黃海槽東西兩側的沉積差異主要表現在冰消期以來沉積厚度、沉積層序、氧同位素記錄上。In this paper, regarding the analysis of stability factors of majiatian tailings fill dam, namely regional geologic structure, rock - soil body of dam foundation, poor geology phenomenon, leach consolidation and chemical consolidation of tailings, seepage water of dam body and king - size flood water of majiatian tailings reservoir, a preliminary demonstration on probability of earthquake liquefaction and seepage failure of dam bodys tailings sand soil, of the dam body failure resulted from abutment landslide and of the flood water overflowing crest, as well as on the contribution of leach consolidation and chemical consolidation of tailings to the stability of dam body has been performed
通過對馬家田尾礦庫區域地質構造、庫區不良地質觀察、尾礦淋濾固結和化學固結、壩體滲透水和庫區特大洪水等因素對馬家田尾礦堆積壩體穩定性影響的分析，初步論證了壩體尾礦砂土的地震液化、滲透破壞、壩肩滑坡使壩體失穩和洪水漫頂的可能性，以及尾礦淋濾固結和化學固結作用有助於壩體的穩定性。In this paper, regarding the analysis of stability factors of majiatian tailings fill dam, namely regional geologic structure, rock - soil body of dam foundation, poor geology phenomenon, leach consolidation and chemical consolidation of tailings, seepage water of dam body and king - size flood water of majiatian tailings reservoir, a preliminary demonstration on probability of earthquake liquefaction and seepage failure of dam body ' s tailings sand soil, of the dam body failure resulted from abutment landslide and of the flood water overflowing crest, as well as on the contribution of leach consolidation and chemical consolidation of tailings to the stability of dam body has been performed

從這一認識出發，將米浪溝灣剖面150ka以來的砂丘堆積劃分為38個旋迴的沙漠期與間沙漠期交替演化過程，並認為，該剖面自那時以來發生的38個砂丘沉積與河湖相或古土壤的演替過程，實際上是這一長期地質時代毛烏素沙漠受東亞冬夏古代季風影響交替演化所致。In the sandy layer, the soil composition gradually increases and a ku - lau rock rock formed by coral fossil structure appeared lying in the south - north direction. the ku - lau rocks were structured with the bricks lying in the east - west direction
沙土層內，土壤質逐漸增加，出現南北向咕?石結構，與東西向磚塊堆積結構，其中咕?石表現先敷上白灰，其次再為水泥。Underneath the surface was a layer of sedimentary yellow soil, which was regarded as coming from somewhere else. it was found that some of the rock materials was the same as on the walkway, which shows that this soil layer had some connections with the the reforming of the pedestrian walkway
表土層底下露出黃褐色堆積土層，屬外來堆土，其中還發現幾片與地表人行步道上的板巖片相同材質的遺留，顯示該土層應與整修人行步道有關。分享友人
