Based on the observation of the outcrops, we studied the details of the sedimental facies in ganchaigou formation, and analysed the variety of sedimental facies, including alluvial - fan facies, braided stream facies, fan - delta facies, lacustrine facies, lacustrine floor fan facies and storm deposit facies
摘要在野外地質剖面研究的基礎上，對柴達木盆地西部古近新近系乾柴溝組進行了詳細的沉積相研究，分析了乾柴溝組發育的沖積扇、河流、三角洲、扇三角洲、湖泊、湖底扇及風暴沉積等幾種沉積相類型。It is revealed through studying the environmental geochemical behavirous of phosphorus that the sedimentary phosphorus in sea - continental margin recorded the paleoclimatic and paleoenvironmental changes information and its critical significance of indicating past - global changes
綜合這些研究成果，有關不同時間尺度的古氣候變化的信息主要是通過對冰芯1 3 、黃土4 、 5 、海底沉積6 、 7 、湖積物8 、樹木年輪9 、洞穴碳酸鹽10 ，以及生物遺跡11等的研究獲得的。The further study shows that the sandstones at the bottom of the lower ganchaigou formation, which is a tr lithostratigraphic unit, were deposited in different stages of base level cycle, and they are not chronostratigraphic unit. so, to identify different sequences, especially high order sequences in analysis of terrestrial stratigraphic sequences, the sequence distribution feature must be fully consided. this view has practical significance for recognizing forming, evolution and filling history of qaidam baisn correctly, and has both theorical and practical meaning for directing further oil exploration
研究還表明，傳統巖石地層單位中下乾柴溝組底部的砂巖代表了基準面變化旋迴不同階段沉積的產物，它們屬于不同的成因單位，也非等時地層單位，因此，在進行陸相層序地層分析時，各級層序尤其是高級層序的識別要充分考慮面上的層序展布特點，這一觀點對正確認識柴達木盆地的形成演化和沉積充填歷史，指導今後的勘探具有一定的理論和實際意義。Middle - upper ordovician seismic sequences and submarine fan deposits in west tadong uplift, tarim basin, northwest china
塔里木盆地塔東凸起西部中上奧陶統地震層序與海底扇沉積The features of these sequences arerbefore sequence i deposited during the rapid subsidence of the depression, the range of the sediment is limited. sequence ii is the first series of source and reservoir rocks of the depression. there are regional unconformity at the bottom of the sequence iii. the rock type are variety. this sequence is evaluated as good source rock, sequence iv is associated with the first section of duhongmu formation, thick mudstone at the bottom and the thick single sandston are the main rock type. this sequence are evaluated as good source rock and reservoir. sequence v associated with the second and the third section of duhongmu. which is mainly mudstone and can be regional capping rocks
層序對應于阿爾善組二段，為深色泥巖與砂礫巖不等厚互層，是本區的第一套烴源巖和儲集層，可以作為本區儲層。層序對應騰格爾組，此時凹陷擴張，沉積層底部具有區域性的沖刷面，巖性變化大，是較好的生油層。層序對應都紅木組一段，下部泥巖發育，單砂層較厚，是主要的生油層和儲層。In this paper, the nucleation process of diamond by filament cvd was analyzed, and enhanced flux of ions by negative substrate bias was investigated in theory
摘要木文對熱燈絲cvd沉積金剛石膜的核化過程進行了分析，從理論上研究了負襯底偏壓增強活性離子的流量。分享友人
