Present location of Pierre Shale–Trinidad Sandstone samples in the Raton Basin (Colorado and New Mexico, USA) and other geologic elements. Maastrichtian paleogeography was possibly somewhat different. Numbered Laramide magmatic centers (brown stars) are listed with references in the Supplemental Material (seefootnote 1). (Geology based on Jones et al., 2010; Gonzales, 2015; Amato, et al., 2017; Pecha et al., 2018; Seedorff et al., 2019.)

The geology, drilling procedures, coal beds encountered, tests for gas, and experience gained are described. The amount of methane, although lower than expected, is consistent with the correlation of coal rank...

(A) Plots of detrital zircon U-Pb age histograms (green bars) and kernel density estimation (KDE) distributions (maroon curves) for Pierre Shale–Trinidad Sandstone (Colorado, USA) samples, calculated with IsoplotR (Vermeesch, 2018). N—number of concordant zircon grains (plotted)/total zircon grains analyzed. 206Pb/238U age is used for zircon <1100 Ma where difference from 207Pb/235U age is no more than–10% and +5% discordant; 207Pb/206Pb age is used for zircon ≥1100 Ma where difference from 206Pb/238U age is no more than–15% and +5% discordant. (B) Proportions of detrital zircons with 70, 160, 1410, 1690, and 1740 Ma age peaks in each Pierre Shale–Trinidad Sandstone sample, calculated from KDE distributions shown in A. (C,D) KDE zircon plots for potential proximal and distal sources, respectively. See text for locations and references.

(A) Th/U ratios of 71 ± 3 Ma detrital zircon of Pierre Shale–Trinidad Sandstone (Colorado, USA) samples versus mean grain diameter calculated as the average of maximum length and width. Error bars on the mean values represent ±1 standard deviation of the sample mean (population standard deviation divided by the square root of the sample size n). (B) Th/U ratios of 71 ± 3 Ma potential sources of detrital zircon; see text for references.

... Formation sandstones in Barbados do show an immature orogenic signature, in contrast to Venezuela–Trinidad Domain 2 sediments, this requires: (1) at least a bathymetric difference, if not a tectonic barrier, between them; and (2) that the Barbados deep-water depocentre was within turbidite transport...

Classification of sandstone samples from Trinidad and Barbados that were evaluated for this study. (a) Collective quartz–feldspar–lithic fragments ternary plot with samples classified according to Pettijohn et al. (1972). Sandstones range from Cretaceous arkosic arenites to Cenozoic (shaded) quartz arenites, sublitharenites and lithic arenites. The sandstone units are shown in (b) arranged in stratigraphic superimposition as labelled (only top half of plot is shown and legend shown in ‘Cretaceous’ only).
