Quaternary Seabed Sediment Characteristics as an indication of VMS-mineral deposits at the South Banda Basin and its surroundings, Indonesia

Abstract The South Banda back-arc basin is a morphotectonic environment that part of the Basin, characterized by flat morphology with depths ranging from 5000m to 6000m. purpose this paper analyze and relate morphometric aspects Quaternary seabed sediment deposits deposited in an active tectonic Sea area, including information on type its distribution as well relation volcanic hosted-massive sulfide (VHMS) or volcanogenic massive (VMS) mineral deposits. lithofacies Arc area were several environments. types are pelagic, hemipelagic turbidite origin Volcanic consist gravel, sand, muddy silt which classified very poorly moderately sorted. grain composition lithic, feldspar, augite, hypersthene, enstatite commonly found arcs troughs. Groups grains composed pyroxene andesite, pumice, tuffite siliceous distributed northern middle arc interpreted originate complex Seram-Gorong islands.
