Composition and age of bottom sediments from the Southern Ocean@en

Geomorphology, geology, stratigraphy, lithology and geochemistry of bottom sediments in the South Ocean are under consideration. Regularities of distribution of iron-manganese nodules, features of occurrence of ore components in the nodules, nodule abundance in bottom sediments have been studied.本研究针对南大洋（South Ocean）海底沉积物的地貌学、地质学、地层学、岩性学及地球化学特征展开探讨，已系统研究了铁锰结核（iron-manganese nodules）的分布规律、结核中矿石组分的赋存特征，以及海底沉积物中铁锰结核的丰度。
