The "J" sandstone is an informal economic term for the Muddy Sandstone. The "D" sandstone overlies the Muddy ("J") Sandstone and production is often reported commingled with the "J".

[Abstract Base‐salt relief influences salt flow, producing three‐dimensionally complex strains and multiphase deformation within the salt and its overburden. Understanding how base‐salt relief influences salt‐related deformation is important to correctly interpret salt basin kinematics and distribution of structural domains, which have important implications to understand the ...Mud, which includes silts (0.0625 to 0.004 mm) and clay (< 0.004 mm) Mixtures are described with a modifying term for a less-abundant size, such as clayey sandstone, sandy siltstone, or muddy sandstone (Fig. 1c).

Mudstone is distinguished from shale by its lack of fissility (parallel layering). [1] [2] The term mudstone is also used to describe carbonate rocks ( limestone or dolomite) that are composed predominantly of carbonate mud. [3]The sandstones are mainly sublithic arenite with angular to subrounded, moderately sorted grains, embedded in muddy matrix.

Sedimentary rock - Sandstones, Clastic Rocks, Stratification: Sandstones are siliciclastic sedimentary rocks that consist mainly of sand-size grains (clast diameters from 2 to 116 millimetre) either bonded together by interstitial chemical cement or lithified into a cohesive rock by the compaction of the sand-size framework ...
