(Table 2, page 313) Chemical composition of radiometrically dated Pacific Ocean manganese nodules

This paper, explores the possibility of using manganese nodules for studying the rates of authigenic removal of trace elements to the ocean floor, i.e. considering only trace elements in hydrogenous phases (Goldberg, 1964) in sediments. It follows the then recent detailed investigations of physiochcmical properties of manganese nodules made by others. In view of the various arguments the developed regarding a slow and possibly entirely authigcnic growth of manganese nodules, the authors were led to the measurements of a host of trace elements in several already radiomctrically dated manganese nodules and sediments.

本论文探讨了利用锰结核（manganese nodules）研究微量元素自生沉积至海底速率的可行性，即仅关注沉积物中水成相（hydrogenous phases）中的微量元素（戈德伯格，1964）。本研究延续了当时新近其他学者针对锰结核物理化学性质开展的详细研究工作。鉴于此前已提出的诸多关于锰结核生长缓慢且可能完全为自生生长的论点，研究者对多份经放射测年定年的锰结核及沉积物中的大量微量元素开展了测定。
