note 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.
