冰川沉積
  • glacial : adj. 1. 冰的；冰狀的。2. 冰河的，冰河時期的。3. 冰冷的，冷淡的。4. 像冰河運動般緩慢的。5. 【化學】結晶狀的。n. -ist 冰河學家，冰河學者。
  • derived : 導生的
  • sediment : n. 1. 沉澱（物）；沉渣。2. 【地質學；地理學】沉積物。
  1. 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。
  2. 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。
