Peridinialean dinoflagellate plate patterns, labels and homologies Peridinialean dinoflagellate plate patterns, labels and homologies
Tabulation patterns for peridinialean dinoflagellate thecae and cysts have been traditionally expressed using a plate labelling system described by C.A. Kofoid in the early 1900's. This system can obscure dinoflagellate plate homologies and has not always been strictly applied. The plate-labelling system presented here introduces new series labels but incorporates key features and ideas...

Application of the Graphic Correlation method to Pliocene marine sequences Application of the Graphic Correlation method to Pliocene marine sequences
Biostratigraphy — the use of paleontological evidence to establish relative chronologies, forms the cornerstone of many sedimentary geological investigations. Several different approaches to biochronology are available. Traditional interval zones, defined on lowest and/or highest occurrences of selected taxa, are used to place bodies of rock in a relative chronological framework. Fossil...

Mélanges and olistostromes in the Appalachians of the United States and mainland Canada; An assessment Mélanges and olistostromes in the Appalachians of the United States and mainland Canada; An assessment
There is no completely accepted definition of a mélange, and the papers in this volume reflect this fact. In our regional assessment, the term mélange is principally used for a technically fragmented and mixed body of rock. A different term, olistostrome, is used for a chaotic and mixed rock body that formed by sedimentary processes such as slumping or gravity sliding. The term...

Alleghanian deformation, metamorphism, and granite emplacement in the central Piedmont of the southern Appalachians 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...
