Application of micro‐CT to resolve textural properties and assess primary sedimentary structures of deep‐marine sandstones

The Depositional Record
Over the past decade, there has been growing interest in the sedimentological community to use micro X‐ray computed tomography to analyse microfacies in sediment cores.

Estratigrafía de Sr y evolución sedimentaria de los depósitos marinos del Mioceno temprano en el antepaís del norte de la Cuenca Austral (o Magallanes), Argentina [PDF]

, 2015
Early Miocene shallow marine deposits in the region of Lago Posadas-Meseta Belgrano (Argentina) represent part of the “Patagoniense” transgression, an Atlantic marine incursion that flooded large part of Patagonia, including the Austral (foreland) Basin (

Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil

Deep Underground Science and Engineering, EarlyView.
Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

Prismatic Sandstone from Missouri

Science, 1892
On the right bank of the St. Francois River, in S.31; T.33, N.; R. 6. E., about 200 yards southwest of the St. Louis Granite Company's quarry, near Knob Lick, Madison County, Mo., is a little sandstone ridge, trending northwest and southeast, nearly 200 yards long, 10 yards wide, and not more than 8 to 10 feet high above the nearly level ground on ...

Creep properties and constitutive model of diabase in deep water conveyance tunnels

Deep Underground Science and Engineering, EarlyView.
The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.
