Hematitic sandstone.

This paper is devoted to study the effect of saturation, with distilled water, on AC electrical conductivity and dielectric constant of a fully and partially saturated hematitic sandstone sample (Aswan area, Egypt). The saturation of the sample was changed from full saturation to partial saturation by air drying.For the pore-fluids of sandstone, dissolved iron ions that end up at the concretion surface must navigate a path involving only pore space. The ion diffusion coefficient is given by Iversen and Jørgensen (1993) as (6) D i = D i 0 1 + n ( 1 − ϕ ) where n = 2 for sandy sediments, D i 0 is the diffusion coefficient for a dilute solution and ϕ ...Ridgely Sandstone Member of the Oriskany Formation: Rockdale Run Chert: Ranges from a light to medium gray.

Several uraniurn deposits are present in the Fall River sandstone of Early Cretaceous age on the northeast flank of the Black Hills, Butte County, South Dakota. The deposits are within a fine-grained, well-sorted, persistent basal sandstone unit that ranges in thickness from 2 to 18 feet and dips about 4 deg NE.

Sandstones of the Juniata, Tuscarora, and Keefer Formations form cliffs, ridges and steep dip slopes. 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.

The microscopic description of the first bioturbated hematitic sandstone/sandy ironstone beds revealed its composition from moderately to well-sorted, angular to subrounded fine- to medium-quartz grains.Limonite, which produces a yellow or (when heated) red powder, was the most popular. Hematite or hematitic sandstone, which yield red or orange powders, were also used. The closest sources for limonite are in north Louisiana or coastal Mississippi, while sandstone could be obtained from central and north Louisiana or the Mississippi coast.The Paleocene Sangiali group represents Sangiali (limestone, glauconitic sandstone and shale), Rakhi Gaj (Girdu member, glauconitic and hematitic sandstone; Bawata member, alternation of shale ...
