Stroud et al. [14] derived an analytical mixing law to calculate frequency-dependent complex dielectric permittivity of brine-saturated clean sandstone or carbonate. This mixing law is referred as SMD model and is a function of total porosity, water saturation, water salinity, relative permittivity of conductive and nonconductive phases, and rock textural parameter describing cementation ... sandstone (noun) sandstone / ˈ sændˌstoʊn/ noun. plural sandstones.

Jan 1, 2001 · By Christine Wilkerson. To classify and map layers of rock, geologists created a basic unit called a formation. A formation is a rock unit that is distinctive enough in appearance that a geologic mapper can tell it apart from the surrounding rock layers. It must also be thick enough and extensive enough to plot on a map.

The grainy, sandpaper-like surface is glassy in appearance. Minor amounts of former cementing materials, iron oxide, silica, carbonate and clay, often migrate during recrystallization, causing streaks and lenses to form within the quartzite.
