(Table 1) Anisotropy of magnetic susceptibility parameters of ODP Hole 134-833B

Ocean Drilling Program (ODP) Sites 832 and 833 were drilled in the intra-arc North Aoba Basin of the New Hebrides Island Arc (Vanuatu). High volcanic influxes in the intra-arc basin sediment resulting from erosion of volcanic rocks from nearby islands and from volcanic activity are associated with characteristic magnetic signals. The high magnetic susceptibility in the sediment (varying on average from 0.005 to more than 0.03 SI) is one of the most characteristic physical properties of this sedimentary depositional environment because of the high concentration of magnetites in redeposited ash flows and in coarse-grained turbidites.

大洋钻探计划（Ocean Drilling Program，ODP）832与833站位，钻探于新赫布里底群岛弧（瓦努阿图）的弧内北奥巴盆地。由邻近岛屿火山岩侵蚀及火山活动所引发的弧内盆地沉积物高火山物质输入，与该沉积物的特征磁信号密切相关。沉积物的磁化率较高，平均变化区间为0.005至0.03以上国际单位制（SI），这是该沉积环境最具代表性的物理性质之一，其成因在于再沉积火山灰流与粗粒浊积岩中富集大量磁铁矿。[…]
