Geoscience Ontology Description

Distinction of intrabasinal, diagenetic, or clastic genesis for very fine-grained carbonate minerals is so interpretive that it is proposed to not define the mudstone category based on intrabasinal vs epiclastic distinction required for clastic sedimentary rock-carbonate sedimentary rock categorization in this system. Schnurrenberger, D., Russell, J. and Kelts, K., 2003, Classification of lacustrine sediments based on sedimentary components: Journal of Paleolimnology, v.29, p141-154. Sedimentary rock consisting of less than 30 percent gravel-size (2 mm) particles and with a mud to sand ratio greater than 1. Clasts may be of any composition or origin.
