    Description: A total of 32 holes at five sites near 1°N, 86°W drilled on Deep Sea Drilling Project (DSDP) Leg 70 (November- December 1979) provide unique data on the origin of the hydrothermal mounds on the southern flank of the Galapagos Spreading Center. Hydrothermal sediments, primarily Mn-oxide and nontronite, are restricted to the immediate vicinity of the mounds (〈 100 m) and are probably formed by the interaction of upward-percolating hydrothermal solutions with seawater and pelagic sediments above locally permeable zones of ocean crust. Mounds as high as 25 meters form in less than a few hundred thousand years, and geothermal and geochemical gradients indicate that they are actively forming today. The lack of alteration of upper basement rocks directly below the mounds and throughout the Galapagos region indicates that the source of the hydrothermal solutions is deeper in the crust.

    Description: Since its discovery in 1974 (Klitgord and Mudie, 1974), the Galapagos mounds hydrothermal field has received much attention. Sediment samples were taken during Leg 54 of the Deep Sea Drilling Project (DSDP) and by other expeditions to the area (e.g., Corliss et al., 1978). While a hydrothermal origin for the mounds sediments has been generally accepted, several different theories of origin for the mounds themselves have been proposed (e.g., Corliss et al., 1978; Natland et al., 1979; Williams et al., 1979). One of the aims of DSDP Leg 70 was to return to the mounds field and, using the new hydraulic piston cor er described elsewhere in this volume, to obtain more complete recovery of mounds sediments than had previously been possible. It was our hope that this would help in our understanding of the nature and origin of these deposits. In this chapter, we describe the results of chemical analysis of over 250 sediment samples taken during the course of Leg 70.

    Chemical analyses of ferromanganese oxide crusts from the Indian Ocean (2022)

    Details
    Publication Date: 2023-08-28
    Description: A suite of ferromanganese oxide crust specimens was collected by R.R.S. Shackleton in 1975 as part of the continuing study at Imperial College of North West Indian Ocean nodules and encrustations. The samples analysed were drilled out at points of varying depth within the specimens using a hand drill with a 2 mm stainless steel bit. The samples were then ground up and dried in a desiccator. They were subjected to a standard HF/HNO3/HClO4 attack, and taken into solution for analysis by atomic absorption spectrophotometry for Fe, M n, Co, Pb, Cu, Zn, Al, Ti, Mg, Ca, Cd and Li. Analytical precisions were generally better than 10 96, and usually better than 5 %. However, Cd and Li had precisions generally worse than 15 % , because their concentrations were nearer the detection limit of the method.

    Description: Hydrothermal deposits of a wide variety of types are being found with increasing frequency on or near actively spreading mid-ocean ridges. However, they also have a potential to occur in other submarine volcanic settings, including island arcs. To follow up indications of mineralization associated with submarine hydrothermal activity in the south-west Pacific island arc, a joint New Zealand Oceanographic Institute/Imperial College research cruise was mounted in May 1981 aboard the RV Tangaroa. During this cruise, over 130 sampling stations were occupied, at one of which were dredged manganese deposits with strong hydrothermal affinities. This is the first report of such deposits from an island arc setting.

    Description: Fossil manganese nodules and encrustations from seamount' and basin' localities in the Transdanubian Central Mountains of Hungary are lithologically, mineralogically and chemically similar to some modern marine ferromanganese oxide deposits, and show no evidence of postdepositional changes other than cementation. Five groups of deposits were encountered: Fe/Mn nodules, encrusted shells, pavements, stains, and Fe oxide encrusted intraclasts, the first three of which are specific to the 'seamount' environment and the last to the basins'. Optical and electron microprobe investigation of the samples shows them to exhibit many similarities with modern ferromanganese oxide deposits, and that many of the nodules are surrounded by a halo of dispersed ferromanganese oxides, strongly suggesting that they continued to accrete metals through the pore waters of unlithified sediments for a period after burial. By contrast, pavements which appear to have grown on hardgrounds at the sea floor show little or no evidence of derivation of metals from underlying sediments. Geochemical investigations on the deposits show the seamount' varieties to be closer in composition to most modern nodules and crusts than the basin' varieties, and that the latter are essentially manganese and trace-element-poor ferruginous deposits. Nevertheless, all can be more or less compositionally equated with modern ferromanganese oxide deposits forming in marginal Atlantic environments, which would be in accord with the proposed depositional environment of the Transdanubian Central Mountains based on other evidence.

    Description: Hydrothermal Mn-oxide crusts have been removed from the Tonga-Kermadec Ridge, the first such hydrothermal deposits to be reported in the S.W. Pacific island arc. In several respects the deposits are similar to hydrothermal Mn-crusts from oceanic spreading centre settings. They are limited in areal extent, comprise well-crystalline birnessite and generally display extreme fractionation of Mn from Fe. They are strongly depleted in many elements compared to hydrogenous Mn deposits but are comparatively enriched in Li, Zn, Mo and Cd. The Group IA and Group IIA metals show strong intercorrelations and the behaviour of Mg in the purest samples may indicate the extent to which normal seawater has influenced the composition of the deposits. Certain aspects of the deposits are not typical of hydrothermal Mn deposits. In particular at least some of the crusts have developed on a sediment or unconsolidated talus substrate. Some crusts, or specific layers within some crusts, display a chemical composition which suggests a significant input from normal seawater.
