Coarser-grained stage two siderites and ankerites show breccia and vein-veinlet textures, and are considered to have formed by replacement during burial diagenetic sub-seafloor fluid flow. measured core permeability show close agreement except in sideritic zones. The presence of siderit e causes a significant shift in the NMR T2 relaxation times and a subsequent decrease in NMR log permeability estimation. The shift to faster T2 relaxation time is primarily due to iron content in the siderite.
