glacial sediment 中文意思是什麼
glacial sediment
解釋
冰川沉積物-
The provenance of the sediment in middle okinawa trough during the last glacial maximum is the shelf of the east china sea. the characteristics of elemental geochemistry ascertain that the sediment was derived from the paleo - changjiang river
末次盛冰期沖繩海槽中部陸源物質來源於東海陸架，元素地球化學特徵顯示這些沉積物主要來源於古長江的入海物質。 -
Comparison of the characteristic parameters of immobile elements, such as ree, sc, th, ti etc and of the characteristics of sedimentology and mineralogy comes to a conclusion that the provenance of the sediment is different in the last glacial maximum and in the sub - interglacial stage, and they have the traits of mixed source. during the last glacial maximum the sediment in the outshelf of the southern east china sea was affected weakly by changjiang river and they are probably derived from the coast mountains of zhejiang - fujian province, which are near the southern east china sea
通過對東海外陸架樣品的稀土元素和sc ， th ， ti等不活潑元素地球化學物源示蹤指標對比，再結合沉積學和礦物學特徵，判斷末次盛冰期與盛冰期以前的沉積物具有不同的物質來源，不同時期的沉積物都具有混合物源的性質，盛冰期東海南部外陸架沉積物受長江物源影響較小，可能來源於距東海南部較近的浙閩沿海山地。 -
In the recent years numerous scientists have found that there appeared many abrupt climatic changes during the last glacial by studying the high - resolution achieves of environmental change such as polar ice - core, deep ocean sediment and loess - palaeosol sequence et al
近十幾年來，隨著研究技術和方法手段的進步，許多科學家通過對極地冰芯、深海沉積物、黃土-古土壤等環境演化信息載體的研究，在末次冰期中發現了許多氣候突變事件。
