The Pennsylvanian System in the Sacramento Mountains, New Mexico, USA


Book Description

"Here, we present new and extensive data on the Pennsylvanian strata in the Sacramento Mountains [...]. Our goals here are to present new data on and to review and revise the Pennsylvanian lithostratigraphy in this area, to present new petrographic and paleontological data, and to interpret the biostratigraphy, general nature of the depositional systems, and sedimentary environments and geological history of the Pennsylvanian strata." -- introduction, page 1.






















The Carboniferous Timescale


Book Description

The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.
