Figure 3.  Generalized cross-section, based on regional seismic lines, showing geology of Brookian strata in eastern NPRA and adjacent areas.  Subsurface thermal maturity control projected onto cross-section from wells shown; surface thermal maturity control based on analysis of outcrop samples.  Generalized locations of Tarn, Meltwater, and Nanuq oil accumulations and of heavily oil-stained Torok outcrops are shown.  Schematic tectonic wedge is based on the interpretations of Moore and Potter (this volume).  Location of this cross section is shown in Fig. 2.
