TABLE 1
Names and locations of wells in Campbell County, Wyoming, in which core was sampled for petrographic analysis of the Sussex "B" sandstone, Sussex Sandstone Member of the Upper Cretaceous Cody Shale. Locations are section, township, and range (glossary). An asterisk (*) marks the estimated core depth to the top of the Sussex "B" sandstone; other depths are actual core depths.

TABLE 2
Thin-section point-count data for Sussex "B" sandstone facies. Facies definitions use those of Tillman and Martinsen (1985). Data are average volume percentages for number (N) of thin sections listed; Q, quartz grains; PQ, polycrystalline quartz; FSP, feldspar grains; RF, rock fragments; GL, glauconite; MM mudstone matrix; MC, clay matrix; MS, mudstone drapes; SID, siderite drapes; PY, pyrite; CHL, chlorite; QC, quartz cement; CT, chert cement; FSP, feldspar cement; CA, calcite cement; KA, kaolinite booklets; PO, porosity; MCP, minus-cement porosity. Sedimentary facies are listed under column name FACIE for the entire data set (ALL), upper chert-pebble lag sandstone (CTSS), central ridge sandstone (CRSS), high- and low-energy ridge-margin sandstones (HRMS, LRMS), wavy-bedded sandstone (WBSS), and inter-ridge sandstone (IRSS) and siltstone (IRST) (Higley, 1992, 1994).
