Detailed stratigraphy for the Angus core, plotted with 5-mm-resolution wt% CaCO3, SiXRF, AlXRF, and δ13Corg data. The numbered circles to the right of the stratigraphic column identify bentonite layers, and the three stars indicate the stratigraphic location of dated ash beds that have been correlated into the Angus core for geochronologic constraints. (A) Calibrated XRF wt% CaCO3 profile from this study, (B) X-ray fluorescence (XRF) scanning results for Si (counts). (C) XRF scanning results for Al (counts). (D) Bulk organic carbon isotope data from Joo et al. (2014). The shaded area indicates the interval of oceanic anoxic event (OAE) 2. VPDB—Vienna Peedee belemnite.

Correlation of the Angus core to the USGS #1 Portland core, using lithostratigraphy, CaCO3, Mn, Fe, and δ13Corg data. For the Angus core, plotted to the right of Bridge Creek Limestone Member lithostratigraphy are: (A) calibrated wt% CaCO3 content, (B) X-ray fluorescence (XRF) scanning results for Mn (counts), (C) XRF scanning results for Fe (counts), and (D) bulk organic carbon isotopes (‰ vs. Vienna Peedee belemnite [VPDB]; Joo et al., 2014). For the USGS #1 Portland core, plotted to the left of Bridge Creek Limestone Member lithostratigraphy (after Meyers et al., 2012a) are: (E) bulk organic carbon isotopes (‰ vs. VPDB; Sageman et al., 2006), (F) Mn content (ppm; Sageman and Lyons, 2003), (G) Fe content (wt%; Sageman and Lyons, 2003), and (H) wt% CaCO3 (Sageman et al., 1997). Adjacent to the Angus core lithostratigraphy, the circles with numbers 1 and 2 are bentonite layers correlated to bentonite layers “B” and “A” (respectively) in the Portland core. The two dotted lines identify the initiation and termination of the oceanic anoxic event (OAE) 2 based on available δ13Corg data (the shaded area for the upper correlation indicates uncertainty in our placement of the termination). Numbers adjacent to the wt% CaCO3 records from the Angus core and Portland core demarcate the proposed high-resolution correlation. Legend for the Angus core lithology is the same as in Figure 2. Legend for the Portland core lithology follows Sageman et al. (2006). HS—Hartland Shale. S. gracile—Sciponoceras gracile, N. juddii—Neocardioceras juddii, W. devon.—Watinoceras devonense, P.f.—Pseudaspidoceras flexuosum, V.b.—Vascoceras birchbyi, M. nodosoides—Mammites nodosoides, C. woolgari—Collignoniceras woollgari.
