My watch list  


Rudite is a sedimentary clastic rock with a grain size exceeding 2 mm (0.08 in).[1] The term is used in the classification of clastic carbonatic limestones, although the granulometrically equivalent terms conglomerate and breccia are often used for limestone too.

Rudites mainly form by erosion of other rocks or turbiditic re-deposition of pebbles or already consolidated rocks. Some rudites contain rounded components and thus belong to the rock-category of conglomerates, others composed of angular fragments are called breccia. The interstices between the coarse grains are filled with a silicatic or carbonatic matrix. Rudites mostly appear as massive or crudely bedded rocks with a wide-spaced foliation and an irregular and wide-spaced cleavage.
