Sequence Stratigraphy And Paleopedology Of Nonmarine Foreland Basins

A strong case can be made that foreland basins are where the casual links between sedimentation and tectonic events were first recognized, as evidenced by the interpretations of geologists working in classic foreland areas. This Special Publication was derived from a Research Symposium entitled "Stratigraphic Sequences in Foreland Basins" held at the AAPG-SEPM joint annual meeting on June, 1992, in Calgary, Alberta, Canada. This volume provides a well-balanced perspective of current research on foreland basin stratigraphy and also serves as another element in the evolving framework that comprises our understanding of foreland basins. Given that so many of earth's resources are found in foreland basins and that foreland basin strata often provide the only preserved record of the tectonic events that led to basin development, the impetus for continued studies of foreland basin strata should remain for many generations of geologists to come.

The principles of stratigraphic paleobiology can be readily applied to the nonmarine fossil record. Consistent spatial and temporal patterns of accommodation and sedimentation in sedimentary basins are an important control on stratigraphic architecture. Temperature and precipitation covary with elevation, causing significant variation in community composition, and changes in base level cause elevation to undergo predictable changes. These principles lead to eight sets of hypotheses about the nonmarine fossil record. Three relate to long-term and cyclical patterns in the preservation of major fossil groups and their taphonomy, as well as the occurrence of fossil concentrations. The remaining hypotheses relate to the widespread occurrence of elevation-correlated gradients in community composition, long-term and cyclical trends in these communities, and the stratigraphic position of abrupt changes in community composition. Testing of these hypotheses makes the stratigraphic paleobiology of nonmarine systems a promising area of investigation.

Explores soil as a nexus for water, chemicals, and biologically coupled nutrient cycling Soil is a narrow but critically important zone on Earth's surface. It is the interface for water and carbon recycling from above and part of the cycling of sediment and rock from below. Hydrogeology, Chemical Weathering, and Soil Formation places chemical weathering and soil formation in its geological, climatological, biological and hydrological perspective. Volume highlights include: The evolution of soils over 3.25 billion years Basic processes contributing to soil formation How chemical weathering and soil formation relate to water and energy fluxes The role of pedogenesis in geomorphology Relationships between climate soils and biota Soils, aeolian deposits, and crusts as geologic dating tools Impacts of land-use change on soils The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the Editors

This volume is the result of an offshore exploration and drilling programme by Soekor (Pty) Ltd in the Republic of South Africa beginning in 1987. Seismic stratigraphic data and borehole information were incorporated and released in what was one of the first detailed and comprehensive published examples of the new field of sequence stratigraphy. The project was conducted over a South African offshore area of 175,000 square kilometres, in the Pletmos, Bredasdorp, and Orange basins, which are examples of divergent basins associated with the breakup of Gondwana.

IAS Special Publication 35, Fluvial Sedimentology VII, comprises ofa series of peer-reviewed papers that were initially presented atthe 7th International Conference on Fluvial Sedimentology, held inLincoln, Nebraska on August 6-10, 2001. The 29 papers in this volume reflect the topical and geographicdiversity of exciting research conducted by fluvialsedimentologists at the beginning of the 21st century. Themesrepresented in this volume include (a) flow, sediment transport,and bedform dynamics, (b) characteristics of modern fluviallandforms, environments and systems, (c) physical analogue andnumerical modeling of fluvial systems, (d) the responses ofQuaternary fluvial systems to climate change, active tectonics,and/or sea-level change, and (e) characteristics of pre-Quaternaryfluvial deposits and evolution of pre-Quaternary fluvial systems.
