The informal Uteland Butte member of the Eocene Green River Formation in the Uinta Basin, Utah is one of the few examples of a continuous petroleum resource play in the world situated in a lacustrine sedimentary basin (Johnson and others, 2015; Birdwell and others, 2016). The datasets compiled here were collected on outcrop samples of the Uteland Butte member with the purpose of better characterizing the geochemical and mineralogical properties and variability through this unit, which represents a period of freshwater conditions in Eocene Lake Uinta in the Uinta Basin. The data have been integrated with outcrop descriptions, geophysical (gamma ray) logs, and interpretations of depositional conditions across geographic...

The Hawaiian-Emperor chain, the surface expression of the Hawaiian mantle plume which has been active for at least 81 Ma, is divided into the Emperor Seamounts (81-47 Ma), Northwest Hawaiian Ridge (NWHR, 47-6 Ma), and Hawaiian Islands (<6 Ma). Hawaiian volcanism evolves through four volcanic stages: alkalic preshield, tholeiitic shield (80-90% volcano volume), alkalic postshield (∼1%), and silica undersaturated rejuvenated (<0.1%). This data release contains tables with new data consisting of major element oxide concentrations, trace element concentrations, and radiogenic-isotope compositions (87Sr/86Sr, 143Nd/144Nd, 176Hf/177Hf, 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb) from postshield basalts from 14 NWHR and young...
The Eocene Green River Formation in the Piceance Basin of Colorado contains some of the richest oil shale deposits in the world (Johnson and others, 2009; Birdwell and others, 2013). The datasets compiled here were collected with the purpose of refining our understanding of geochemical variability through the depositional history of Eocene Lake Uinta in Piceance Basin. The effects of salinity, water column stratification, and redox conditions were of particular interest. The inclusion of basin center (cores) and basin margin (outcrop) samples through the full stratigraphic interval of the Green River Formation facilitated temporal and spatial assessment of trends within the basin. Geochemical and sedimentologic...

Petroleum source rocks deposited during Cenomanian – Turonian time (late Cretaceous) are major generators of continuous and conventional oil and gas resources in the Gulf of Mexico Basin. The Eagle Ford Shale is a particularly important petroleum system and represents a substantial fraction of total oil and gas production in the United States. Significant lateral and vertical geochemical and mineralogical variability have been identified in previous studies of the Eagle Ford Shale, but most recent work has focused on the area of the play southwest of the San Marcos Arch. As part of a larger USGS coring program to examine important continuous oil and gas plays in the Texas-Gulf Coast region, the USGS Gulf Coast Petroleum...
