In the older rocks below these glacial deposits are detrital uraninite and pyrite, two minerals considered evidence for very low levels of atmospheric oxygen
這些冰河沉積物下方的較老巖層,是瀝青鈾礦與黃鐵礦碎屑;這兩種礦物被認定為大氣中氧氣極為稀少的證據。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。On the basis of the types of sand stone, light and heavy mineral associations, planimetric map of sedimentary facies and directions of palaeoflow, it is considered that detrital material of terrigenous deposit of chang6 - 8 oil - beds in this area come from southwest provenance, northeast provenance, west provenance and south provenance, respectively, which are the denudation area of huating - longxian county in southwestern, yinshan ancient land in the northern, the denudation area of yantong mountain and tongxin to the west of yangjiajuzi - yinjiacheng county and qinling ancient land in the southern
根據砂巖類型、輕、重礦物組合、沉積相帶平面展布及古水流方向等特徵的分析,認為研究區延長組長6 ? 8油層組陸源碎屑物質來自西南、東北、西部和南部四大物源區,分別為西南華亭?隴縣一帶剝蝕區,北部陰山古陸,西部的楊家咀子、殷家城以西的煙筒山、同心地區剝蝕區和南部秦嶺古陸。1. the framework of mesozoic strata in the north margin of the dabie orogenic belt was reestablished according to the discovery of the tuff beds and volcanic debris in zhougongshan and fenghaungtai formations, along with their isotope ages and the correlations of sedimentary facies and heavy minerals
在周公山組中在鳳凰臺組中發現了火山凝灰巖層利火山巖碎屑,結合同位素年代學研究以及沉積相和重礦物對比,重新釐定了大別造山帶北緣中生代地層的格架。By studying the lithologjcal and mineral parameters ( pebbled elastics percent ratio, clastic maturation index, heavy crop stability factor ) of mesozoic sedimentary strata, the result shows that the northern boundary of present basin is near to the boundary of original basin and the moving distance of elastics is short, but the southern boundary of present basin is far from the boundary of original basin and the moving distance of elastics is long. the fades of northern basin are mainly delta fades and the fades of middle and southern basin are lacustrine fades
通過對盆地中生代沉積地層中各種巖礦參數(碎屑巖含礫百分比、碎屑成熟度指數和重礦物穩定系數)分析和綜合研究認為,今盆地北部距離原始盆地沉積邊界較近,碎屑物搬運距離較短;南部距離盆地古沉積邊界較遠,沉積物搬運距離較遠;中生代盆地北部主要為三角洲沉積相,中南部為湖泊相沉積。The sediments in the core are weakly weathered, lightly abraded and bad sorted, they have the same feature as river sediment, which is derived from near source and did not experience seriously transformation by ocean. due to the rate of insufficient sediment supply the sedimentation rate is low
碎屑礦物風化程度低,磨蝕不顯著,分選較差,河流砂特徵明顯,沉積物來自於近源,由河流輸送入海,海洋改造不十分強烈,由於物源供應不足,沉積速率較低。分享友人
