Marine ferromanganese crusts and nodules host high concentrations of many economically interesting metals such as platinum (Pt), with Pt concentrations in the range of 44 to 3207 ppb in 182 analyzed samples from various locations in the global ocean.

Modern massive sulfide deposits are known to occur in diverse tectonic settings and it is generally expected that hydrothermal deposits of similar geological settings shall have more or less similar mineralogical and geochemical signatures. However,

Little is known about the role of island arcs as hydrothermal sources to the ocean when compared to the extensive research that has been carried out on hydrothermal systems at spreading ridges, although increasingly more work is being done on intraoc

Three sediment cores taken from the Central Sea of Marmara were sedimentologically and geochemically investigated. All the cores show a continuous sedimentation record. According to isotopic age-dating measurements, two of the cores cover an age rang

Hydrothermal sulfides were recovered from the 16°50′S triple junction area in the North Fiji Basin, at a water depth of ca. 1900 m. The chimney samples can be divided into three groups based on their major metal contents: 1) type 1 (Fe–Cu-rich),

Sulphate concentration profiles with non-constant gradients are reported from porewater samples in continental margin sediments. Recent results on a sediment core from the Ganos Fault in the Sea of Marmara revealed a porewater pattern with two gradie

This article focuses on possible geochemical consequences of potential industrial activities in the deep sea, such as manganese nodule mining, for the heavy metal cycle of the deep sea and possible reactions of the benthic ecosystem. The metal fluxes
