FIGURE 2. Distribution of key petrographic constituents sorted according to Smackover depositional facies. Compilation of thin-section point-count data from Appendices in Esposito (1987) and Moore (1991). Number of thin sections per facies: lagoon (8): ramp (11); oolitic (6); buildup (2); slope (19); and basinal (5).
