note Distinction of intrabasinal, diagenetic, or clastic genesis for very fine-grained carbonate minerals is interpretive in many cases. If there is uncertainty on the mudstone category based on intrabasinal vs epiclastic distinction required for clastic sedimentary rock-carbonate sedimentary rock categorization in this system, it is recommended to use the generic_mudstone category. This category is the union of the various fields labeled 'mudstone' with various qualifiers in Folk, 1954, Figure 1a, although Folk's (1954) category labeled 'mudstone' is a much more restricted category. The CGI category is equivalent to category labeled 'Mudrock' in SLTTs (2004), not to the category labeled 'Mudstone' adopted by that system from Folk (1954).
