SEQUENCE STRATIGRAPHY OF A SOUTH FLORIDA CARBONATE RAMP AND BOUNDING SILICICLASTICS (LATE MIOCENE-PLIOCENE)

CARBONATE RAMP AND BOUNDING SILICICLASTICS TEMPORAL AND SPATIAL BOUNDARIES

Lithologic units of primary interest in this study, from oldest to youngest, are the Peace River Formation of the Hawthorn Group, Ochopee Limestone Member of the Tamiami Formation, and an unnamed sand member (Fig. 2). Facies associations presented for the Peace River Formation, Ochopee Limestone, and unnamed sand are based on examination of cores and on existing descriptions within the study areas outlined in Figure 1.

Figure 2. Correlation of chronostratigraphy, lithostratigraphy, and sequence stratigraphy recognized in much of the study area. Modified from Olsson (1964), Hunter (1968), Miller (1990), Missimer (1992), Brewster-Wingard et al. (1997), Missimer (1997), Cunningham et al. (1998), Guertin et al. (1999), Missimer (1999), Weedman et al (1999), and Reese and Cunningham (2000, in press). The Long Key Formation occurs in southernmost peninsular Florida and the Florida Keys (Cunningham et al., 1998). DS1, DS2, DS3, and DS4 are depositional sequences, and CS2 and CS3 are condensed sections. Intervals I, II, and III of Guertin et al. (1999) are integrated into the correlation scheme.  [larger image]
