Book Description
Since the beginning of the last century, the lower Jurassic to mid-Miocene pelagic succession exposed along the valleys of the Umbria and Marche Apennines of Italy represented a fertile playground for generations of earth scientists. This GSA Special Paper provides a reappraisal of the geological and integrated stratigraphic research, which was carried out by scores of earth scientists in the gorges around the medieval city of Gubbio over the past fifty years. Following review chapters about pioneering sedimentologic, biostratigraphic, and magnetostratigraphic studies of the Gubbio sections, a series of papers presents new, original data addressing different stratigraphical, paleoenvironmental, and structural geological aspects of particular Cretaceous to Paleogene intervals, including the still much-debated K-Pg Boundary Event in the worldwide famous site of the Bottaccione Gorge, where the Alvarez theory of global mass extinction caused by a catastrophic extraterrestrial impact was born in 1980.

Book Description
Integrated stratigraphy is essential for⧫ detailed paleoecologic studies of critical intervals in Earth history⧫ the calibration of the time scale for global use⧫ the establishment of Global Stratotype Sections and Points (GSSPs) for the definition of chronostratigraphic boundaries.This book constitutes an excellent and probably unique example of how interdisciplinary stratigraphic and geochronologic studies are approached with modern methodologies and techniques.It contains numerous unpublished, accurate radioisotopic dates of volcano-sedimentary layers interbedded in fossiliferous marine and continental Miocene sequences representing Mediterranean and Pacific environments. New, extremely detailed paleontologic data which constitute the basis for an accurate definition of the Miocene biostratigraphy, and the study of the ecologic evolution of Miocene marine environments are also included.The chapters are complimented by black-and-white photographs, graphic figures, and tables.Stratigraphers, paleontologists and sedimentologists plus geologists working in oil companies will certainly find this work of interest.

Book Description
This book contains six chapters dealing with the investigation of seismic and sequence stratigraphy and integrated stratigraphy, including the stratigraphic unconformities, in different geological settings and using several techniques and methods, including the seismostratigraphic and the sequence stratigraphic analysis, the field geological survey, the well log stratigraphic interpretation, and the lithologic and paleobotanical data. Book chapters are separated into two main sections: (i) seismic and sequence stratigraphy and (ii) integrated stratigraphy. There are three chapters in the first section, including the application of sequence and seismic stratigraphy to the fine-grained shales, to the fluvial facies and depositional environments, and to the Late Miocene geological structures offshore of Taiwan. In the second section, there are three chapters dealing with the integrated stratigraphic investigation of Jurassic deposits of the southern Siberian platform, with the stratigraphic unconformities, reviewing the related geological concepts and studying examples from Middle-Upper Paleozoic successions; and, finally, with the integrated stratigraphy of the Cenozoic deposits of the Andean foreland basin (northwestern Argentina).

Book Description
Cyclostratigraphy is concerned primarily with measuring geological time and the time units used in this approach are sedimentary cycles. Milankovitch cycles mark time intervals of tens of thousands to several millions of years. Such cycles are the result of variations in the Earth's position in relation to the Sun and these in turn determine the climatic variations. The Milankovitch theory was resurrected in the 1960's when evidence from Pleistocene deep sea sediments linked orbital variations and climate.This monograph discusses sedimentary cycles and their use in measuring geologic time. There is considerable effort made to clarify the term "sedimentary cycle", in particular, the two opposing concepts of cyclic stratification and event stratification. The recognition of sedimentary cycles and of Milankovitch cycles specifically, is considered and care is taken with the question of relating sediment thickness to time. Several examples from the Carboniferous to the Cretaceous are given to show how cyclostratigraphy can be applied to current geological problems. This volume should be of interest to geologists involved with stratigraphical analysis and basin analysis.
