USGS Publication: Scientific Investigations Report 2012–5159The Upper Cretaceous Austin Chalk forms a low-permeability, onshore Gulf of Mexico reservoir that produces oil and gas from major fractures oriented parallel to the underlying Lower Cretaceous shelf edge. Horizontal drilling links these fracture systems to create an interconnected network that drains the reservoir.

Scanned copies of three legacy USGS publications with detailed stratigraphy of Late Cretaceous and Early Tertiary rocks in eastern Utah and western Colorado are now available online. MF 1050: five measured sections, in the Mesa Verde Group and Wasatch Formation, in the vicinity of De Beque Colorado including palynological data. MF-1997: eleven detailed measured sections along the Douglas Creek Arch in eastern Utah and western Colorado, including mollusk fossil and palynological data. I-1974: detailed cross sections correlating Upper Cretaceous and Lower Tertiary rocks between the Uinta and Piceance Basins of eastern Utah and western Colorado.

Outside Publication: Mathematical GeosciencesMathematicians and geochemists have long realized that compositional data intrinsically exhibit a structure prone to spurious and induced correlations. This paper demonstrates, using the Na–Cl–Br system, that these mathematical problems are exacerbated in the study of sedimentary basin brines by such processes as the evaporation or dissolution of salts owing to their high salinities.

USGS Publication: Scientific Investigations Map 3214
This publication presents a thermal maturity map of Devonian shale in the Illinois, Michigan, and Appalachian basins. The map shows outlines of the three basins (dashed black lines) and an outline of Devonian shale (solid black lines).
