Supplemented graphic correlation: A powerful tool for paleontologists and nonpaleontologists
The graphic correlation technique of Shaw (1964) is not restricted to biostratigraphic applications. Supplemented graphic correlation (SGC) expands the original technique to include nonunique events (log patterns) to add to the understanding of the geologic history of an area. Dinocyst and acritarch occurrence data and single-point resistance electric logs from three Paleocene to Eocene cores in t

Alleghanian deformation, metamorphism, and granite emplacement in the central Piedmont of the southern Appalachians
Evidence of late Paleozoic (Alleghanian) penetrative deformation, amphilbolite-facies, metamorphism, and syntectonic granite emplacement has been found in an area of the central Piedmont in the southern Appalachians. The High Shoals Granite batholith in the Kings Mountain belt of south-central North Carolina consists of coarse-grained, megacrystic biotite granite with a strong, nearly vertical, gn

Pacific Enewetak Atoll Crater Exploration (PEACE) program, Enewetak Atoll, Republic of the Marshall Islands. Part 1: Drilling operations and descriptions of boreholes in vicinity of KOA and OAK craters
From mid-1984 through mid-1985, the United States Geological Survey (USGS) engaged in an investigation of two craters formed from high-yield, near-surface nuclear bursts in the Marshall Islands at Enewetak Atoll (figures 1 and 2). Supported by the Defense Nuclear Agency (DNA), this cooperative venture is referred to by the acronym PEACE, derived from its official name, Pacific Enewetak Atoll Crate

The Valley and Ridge Province of eastern Pennsylvania - Stratigraphic and sedimentologic contributions and problems
Many contributions that have led to a better understanding of Appalachian geology have resulted directly from work in the folded Appalachian Mountain and Great Valley sections of the Valley and Ridge physiographic province of eastern Pennsylvania. Disagreements have been common since H.D. Rogers first described the geology of the area in 1858. Many differing opinions still exist regarding the stra

Age of biostratigraphic horizons within the Ordovician and Silurian systems
Three samples that have a bearing on the age of horizons within the Ordovician and Silurian systems, two previously dated by the conventional K-Ar method and one by the 40Ar/39 Ar total-fusion method, have been reanalysed using the 40Ar/39Ar age-spectrum method. Conventional K-Ar and total-fusion 40Ar/39Ar ages can always be questioned because of the relative ease with which the K-Ar system can be
