Sandstone outcrop of the Pilgujärvi Sedimentary Formation from which Ru5410 was sampled. b. Thin tuff in outcrop (white arrow) from the base of the Pilgujärvi Volcanic Formation (Ru5610).The Bigrlyi deposit is a tabular, sandstone-hosted, uranium–vanadium deposit of Carboniferous age located in the Ngalia Basin of central Australia. The deposit is similar to the continental, fluvial Saltwash-type of sandstone-hosted U-V deposits which are well known from the Colorado Plateau, USA. Most mineralization at Bigrlyi occurs as thin, multiple-stacked, stratiform lenses at the base ...Hematitic sandstone was never colonized at a rate greater than limestone, but quartz was always colonized more rapidly than calcite. The use of single-crystal minerals (quartz and calcite) in a nested factor experiment showed that the effect of the minerals on colonization was statistically significant, but that differences among the immersion ...The Bigrlyi deposit is a tabular, sandstone-hosted, uranium–vanadium deposit of Carboniferous age located in the Ngalia Basin of central Australia.

Electrical conductivity (or resistivity) is a bulk property of material describing how well that material allows electric currents to flow through it. Resistance is the measured voltage divided by the current. This is Ohm's Law. Resistance will change if the measurement geometry or volume of material changes.Sandstone can be divided into three members: the basal Virgelle Sandstone Member which ranges in thickness from 80 to 130 ft (24-40 m) and the informally designated middle and upper members which together are as thick as 180 ft (60 m). The total Eagle Sandstone ranges from approximately 200 to 300 ft (61-91 m) in thickness. Each of these

The distinctive hematitic sandstone beds of the Rose Hill Formation cover any dip slopes with red sandstone blocks. Other formations are less well exposed and form lower slopes and valleys.
