My watch list  


Arenite is a sedimentary clastic rock with sand grain size between than 0.063 mm (0.00256 in) and 2 mm (0.08 in).[1] The term is used in the classification of clastic carbonatic limestones, as the granulometrically equivalent term sandstone is not appropriate for limestone.

Arenites mainly form by erosion of other rocks or turbiditic re-deposition of sands. Some arenites contain a varying amount of carbonatic components and thus belong to the rock-category of carbonatic sandstones or silicatic limestones. Arenites often appear as massive or bedded medium-grained rocks with a medium- to wide-spaced preferred foliation and often develop a pronounced cleavage.
