Description Brittle quartz sandstone, dark blood red, fine to coarse grained, hematite cemented. Quality of this material is widely varied from extremely high quality that glistens, to poor quality that was seldom used. This material is sometimes mistakenly referred to as hematitic sandstone.This hematitic cement, iron hematitic bands, and concretions have been proven from field observations to be of syngenetic origin, where the iron and uranium are co-precipitated with sandstone. But in some locations, this syngenetic iron are remobilized and re-deposited completely discordant to bedding and is filling the fractures.Close mobile search navigation. Article navigation.
