The Catksill Delta consists of many lobes shed from the rising Acadia Mountains during the Devonian Period. The delta is composed of a combination of marine and non-marine sediments that accumulated along the shoreline of the Kaskaskia Sea. The book attempts to draw together the sedimentary processes which shaped the delta along the western Acadia Mountain.Chapter 1 summarizes the Acadian Orogeny, its paleogeography including the Avalonian terranes. It provides a review of orogenic events, collisions, tectophases, the Acadian foreland basin, delta complex, and a brief discussion of the Kaskaskia Sea. Chapter 2 begins the discussion of the Catskill Delta Complex, addressing the paleo-continental setting, reconstruction, and summarizes paleo-magnetic tectonic models. Chapter 3 presents the Catskill deltaic clastic deposition including the Catskill Formation, paleogeography, paleo-cllimate, and sedimentary processes. Chapter 4 presents the Catskill delta basin facies development controls including its paleogeography, paleo-climate, tectonic regime, origin of black basinal facies, and three phases belonging to a proposed climate model. Chapter 5 addresses the shallow marine and non-marine strata. Chapter 6 discusses unusual marginal marine lithofacies. Chapter 7 summarizes the quantitative interpretation of ancient river systems in the Oneonta Formation of the Catskill megafacies. The book ends with Chapter 8 discussing the Upper Devonian turbidite sequence of central and southern Appalachian Basin and contrasts it with submarine fan deposits.

A guide for the layperson to the geology of New York State's Catskill Mountains.

Classically orbital cycles have been recognized in pelagic and lacustrine sequences characterized by quiet sedimentation, not disturbed by tectonics. Hoiwever, there is now increasing recognition that orbital cycles do influence climate and oceanography in general terms. There is also increasing acceptance of the possibility at least that the effect should be felt over large parts of the Earth's surface and that orbital cycles may well leave signs in other sedimentary environments that are commonly considered to be dominated by tectonics and eustasy. Containing thirty-one papers from a symposium held at the International Sedimentological Congress in Nottingham in 1990, this volume spans a range of topics from the astronomical theory behind orbital forcing, to field studies dealing with a broad range of sedimentary environments, and to modelling and simulation. State-of-the-art research papers. International expert authorship. The latest research in the highly topical subject of orbital forcing.
