Manganese: Predominant Role of Nodules and Crusts
The importance of manganese in the marine environment can be deduced from the fact that it is the tenth most abundant element in the earth’s crust (av. cone. 0.093%) and is available in two valencyExpand

Environments of formation of ferromanganese concretions in the Baltic Sea: a critical review
Abstract Ferromanganese concretions from the Baltic sea can be divided into three main types based on their abundance, morphology, composition and mode of formation; those from the Gulfs of Bothnia,Expand

Mineralogy and composition of Kuroko deposits from northeastern Honshu and their possible modern analogues from the Izu-Ogasawara (Bonin) Arc south of Japan: Implications for mode of formation
The Kuroko deposits of NE Honshu are a key type deposit for the study of volcanogenic massive sulfide deposits. However, these deposits have not been studied in detail since the early 1980's andExpand
