    Chemical and mineral compositions of bottom sediments from the East Pacific Rise near 13°N
    PANGAEA
    In:  Supplement to: Markov, Yu D; Mozherovsky, A V; Vashchenkova, N G (2004): Metalliferous sediments in the active rift zone of the East Pacific Rise. Pacific Geology, 23(5), 40-53

    Description: During underwater photography and sampling of the rift valley bottom in the axial part of the East Pacific Rise, where water transparency is reduced due to hydrothermal input, ore manifestations have been found. The bottom is covered by them as by a jacket on both sides from the EPR axial zone. However, exposed pillow-lavas and clumpy blocks in rift ledges are covered by a thin metal-bearing film. It is supposed that sedimentation results mainly from hydrothermal input of dissolved chemical elements in seawater, their transformation on the geochemical barrier, and subsequent deposition as particulates. Contents of ore components in metalliferous sediments have been measured by atomic-absorption and X-ray radiometry methods. Sediment age has been determined as Middle Pleistocene - Holocene. Maximal hydrothermal activity was at the beginning of Early Holocene, about 10 Ka. A smoker has been found on the western slope of the rift valley.

    Composition of bottom sediments from the Clarion Fracture Zone
    PANGAEA
    In:  Supplement to: Markov, Yu D; Mozherovsky, A V; Pushkar', V S; Vashchenkova, N G; Nechaev, Victor P (2005): Sedimentation features and stratigraphic correlation of unconsolidated deposits from the Clarion Transform Fault Zone (Northeast Pacific). Pacific Geology, 24(4), 24-43

    Description: New data on lithology and stratigraphy of Cenozoic sediments from the Clarion Transform Fault Zone (Pacific Ocean) have been obtained on the base of polygon studies. It has been established that on different blocks (uplifted and subsided) of the Clarion tectonic structure deposits of different age (Eocene to Quaternary) occur. Unconsolidated sediments have been deposited under pelagic conditions since Eocene (probably, since Early Cretaceous) until now. Their mineral composition and content of different ore components are given.

    Chemical composition of layer silicates from the Sado Ridge, Sea of Japan
    PANGAEA
    In:  Supplement to: Markov, Yu D; Mozherovsky, A V; Derkachev, A N; Barinov, N N; Sereda, N A (2002): High-Fe layer silicates of the Sado Ridge, Japan Sea. Lithology and Mineral Resources, 37(2), 121-129, https://doi.org/10.1023/A:1014868332041

    Publication Date: 2023-05-12
    Description: Detailed mineralogical investigations of high-Fe layer silicates from loose sediments (glauconite sands) of the Sado Ridge revealed that green aggregates found on submarine rises of the Japan Sea floor have different genesis. It was demonstrated that round dark green grains approximate micas in composition. Primary volcanic rocks presumably have undergone extensive secondary alterations and then were disintegrated. Their disintegration products (protoceladonite) filling pores were redeposited and buried in sediments for a long time. Angular green grains mainly represented by smectite also formed at lower temperatures during disintegration of altered volcanosedimentary rocks. These younger grains had no prolonged exposure. Pseudomorphs of siliceous microplankton consist of both hydromica and smectites. They are presumably authigenic products formed with participation of microorganisms or electrostatic processes (spherical shape), or their combination. The formation mechanism of minerals filling cavities in pyroclastics is not entirely clear.

    (Table 1) Chemical composition of Fe-rich layered silicates from the East Korean Rise, Japan Sea
    PANGAEA
    Details
    Publication Date: 2023-05-12
    Description: Mineral and chemical compositions of highly ferruginous layered silicates (HLS) of glauconite sands occurred on the East Korean Rise outside volcanic structures and on an unnamed volcano and the Chentsov Volcano have been studied. The use of cluster and discriminant analyses has resulted to more objectively distinguished groups among HLS, and the use of factor analysis - to illustrate correlations between chemical elements in different groups. It has been found that green mineral assemblages of the East Korean Rise are heterogeneous in terms of morphology, composition and origin, and their formation is a complex multistage process including both neoformation and degradation.
