Hematitic sandstone
The ore grades laterally into hematitic conglomerate or hematitic sandstone. The sediments of the Yampi Formation were deposited near a shoreline where iron-rich heavy minerals were concentrated on a beach or nearshore bar by prolonged reworking.

The scheme was developed for classifying sandstones and shales based on their geochemical composition, which could be determined from log data of at the time new geochemical logging (bore-hole) tools. The classification is a further ... We report paleomagnetic data for 26 accepted sites collected in two sections of flat-lying strata of the upper Carnian-lower Norian (∼225 Ma) Dockum Group, northwest Texas.
