FIGURE 6—Basal Triassic facies in the Great Bank of Guizhou. See Fig. 2A for locations. Fossil types indicated as follows: g=gastropod, b=bivalve, f=fusulinid, r=Renalcis. (A) Close up of wavy bedding with stromatolitic appearance in calcimicrobial framestone at Dajiang. Hammer for scale. (B) Slab of calcimicrobial framestone from Dajiang. Darker colored framework is composed of calcified globular, tufted, and dendritic structures similar to Renalcis (r) that enclose irregular network of internal cavities partly filled with internal sediment (s). See Lehrmann (1999) for petrographic details of this facies. (C) Polished slab of the PTB from Langbai. Scale bar in centimeters. PTB event horizon is represented by abrupt change (white line) at the boundary between the skeletal packstone of the Wujiaping Formatation (lower) and calcimicrobial framestone (upper). Small spherical white grains in the packstone (lower) are Palaeofusulina (f). The calcimicrobial framestone (upper) is composed of calcified black globular fossils (r) surrounding lighter-colored irregular internal cavities. (D) Thin section of molluscan grainstone from Heping. Note that most shells are randomly oriented and preserved only as thin micritic envelopes filled with sparry calcite (arrows). Scale is 1 mm. (E) Thin section of molluscan grainstone from Heping. Note micrite (arrows) and peloidal internal sediment perched above bivalve shells (b). Scale is 1 mm.

Petrographic characteristics of platform-margin oolite grainstone facies. (A, B) Ooid lime grainstone with giant ooids from the southern margin of the Great Bank of Guizhou at Bangeng ( Figure 2 for location).

(C) Oolitic grainstone with ooids up to 3 mm and composite coated grains from the northern margin of the Great Bank of Guizhou, Xiliang area. Note the alternation of micritic cortical layers with a detailed fabric preservation and sparry layers with destroyed fabrics and brittle compaction of adjacent layers (arrows). Sparry layers are interpreted to have originally been aragonite. (D) Oolitic lime grainstone with rounded intraclasts and composite coated grains showing an evidence of repeated abrasion and recoating. Arrows indicate alternation of cortices with fabric-destructive sparry layers (original aragonite) and micrite layers (calcite). Southern margin of the Great Bank of Guizhou, Bangeng area.
