U-Pb geochronology of the Late Cretaceous Eagle Ford Shale, Texas; defining chronostratigraphic boundaries and volcanic ash source
The Eagle Ford Shale and equivalent Boquillas Formation (Late Cretaceous) contain abundant volcanic ash beds of varying thickness. These ash beds represent a unique facies that displays a range of sedimentary structures, ...
Quantitative assessment of pore types and pore size distribution across thermal maturity, Eagle Ford Formation, South Texas
Scanning electron microscopy of Ar-ion milled samples from the Eagle Ford Formation, South Texas shows that the character and abundance of porosity changes significantly across burial conditions as a result of compaction, ...
Lithologic heterogeneity of the Eagle Ford Formation, South Texas
Grain assemblages in organic-rich mudrocks of the Eagle Ford Formation of South Texas are assessed to determine the relative contributions of intra- and extrabasinal sediment sources, with the ultimate goal of producing ...
