Fig.6 Northwest-southeast stratigraphic cross-section. Datum is base Heebner Shale (unit
14; top Muncie Creek Genetic Set). The section length is 200 miles (320 km). Vertical scale
shown in feet and meters along left margin. Vertical exaggeration is approximately 1100
times. Twenty-five wells are used indexed at top of cross section in numbers surrounded by
a box. Numbers correspond to well numbers in Fig. 4 and 5. Natural gamma-ray data are
presented in color. Ten-level color scale located in lower left. Warmer and lighter colors correspond to lower gamma ray. Yellow and pink intervals are limestone and blue and purple
are clastics. Condensed sections with high gamma radiation are colored dark blue-gray to
white. Correlation lines connect correlatable condensed sections and flooding units in
GSUs. Lithostratigraphic units (formation level) which are part of GSUs are numerically
coded within the cross section (1 Hertha limestone; 2 Swope limestone; 3 Dennis limestone;
4 Cherryvale Formation; 5 Dewey limestone; 6 lola limestone; 7 Argentine limestone; 8 Farley limestone; 9 Platsburg limestone; 10 Stanton limestone; 11 Stalnaker sandstone; 12
Douglas limestone; 13 Toronto limestone; 14 Heebner shale; 15 Oread limestone). Munice
Creek Shale is thin elevated gamma ray shale above Dewey limestone (5). Nuyaka Creek
Shale is thin shale following lowermost correlation line below Hertha limestone (1). Intervals bounding genetic sets are identified as follows: Nuyaka Creek genetic set (Nuyaka
Creek Shale to Muncie Creek Shale) and Muncie Creek genetic set (from Muncie Creek
Shale to Heebner Shale). Previous work has established correlation of wireline logs to numerous cores and outcrops. Biostratigraphic correlations, where available, have confirmed
physical correlations. Cross-section was generated using PfEFFER software as a single Excel
spreadsheet. Visual Basic module to generate cross section was written by Saibal Bhattacharya
