Resistivity, porosity, grain density and CEC for samples of ODP Hole 118-735B@en

The resistivity, porosity, and cation exchange capacity of 29 gabbroic samples recovered in Hole 735B during Leg 118 of the Ocean Drilling Program (ODP) were measured in the laboratory at room temperature and atmospheric pressure. The samples of lithologic Units IV and VI containing iron and titanium oxides have the highest electrical conductivity and the largest grain density sampled in Hole 735B. The fresh samples are the most resistive of the data set, and the tectonized samples (either due to plastic or brittle deformation) have intermediate values. […]

大洋钻探计划（Ocean Drilling Program, ODP）第118航次在735B钻孔中回收的29件辉长岩样品，其电阻率、孔隙度与阳离子交换容量已于实验室室温及常压条件下完成测试。其中赋存铁钛氧化物的岩性单元IV与VI的样品，具备本钻孔采样样品中最高的电导率与最大的颗粒密度。新鲜样品为本数据集电阻率最高的样本，而经构造变形（塑性变形或脆性变形）的样品电阻率则处于中等水平。[…]
