Sideritic.
Locally and rarely the sandstone is tightly cemented by siderite or pyrite rather than quartz, in which case the terms sideritic sandstone or pyritiferous sandstone are applied. Well-sorted porous sandstone varies greatly in hydrocarbon content, ranging from slightly oil-stained sands to sands that are partly or completely saturated with oil.

Despite this,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. NMR total porosity is unaffected byThe chemical data shows that the ironstones with composition largely reflecting the primary host rocks are of two types; the marine sideritic and fresh water sideritic ironstones (Akinlotan, 2019).
