Book Description
Combining field research of outcrop geology and investigating the recent formation of carbonate rocks in coastal environments the author gives an introduction in sequence stratigraphy. Using computer simulations the book focuses on four questions, regarding the geometry of carbonate wedges, sequences comparable with geotectonic cycles, their influence by geoidal pulses and the determination of these geoidal pulse distribution in geological time. Examples from the Alps and Florida show that ramps and divergent patterns, megabreccias, drowning of carbonate platforms etc. are results of global short-term sea level falls, interpreted as geoidal eustasy. This volume will be a fruitful supplement for the interpretation and understanding of sequence stratigraphic sections not only for scientists and students but also for researchers in the oil andgas industry.

Book Description
This book provides a general introduction to impact stratigraphy, with emphasis on the recognition of distal impact ejecta in the field, by focusing on the impactoclastic layers of the Umbria-Marche sequence in Central Italy, with an almost perfect stratigraphic record over the last 200 Million years. A general introduction to impact cratering and a discussion of distal ejecta and impact layers around the world is followed by a detailed description of the record of the impact of extraterrestrial bodies in sediments of the Umbria-Marche Apennines. The volume is of interest to a diverse audience in the geological and planetary sciences, ranging from (upper) undergraduate to research level. This book can also be used by students and researchers as a field guide to some of the most important Italian impact layers.

Book Description
This book contains state-of-the-art continuous wavelet analysis of one and more dimensional (geophysical) signals. Special attention is given to the reconaissance of specific properties of a signal. It also contains an extension of standard wavelet approximation to the application of so-called second generation wavelets for efficient representation of signals at various scales even on the sphere and more complex geometries. Furthermore, the book discusses the application of harmonic (spherical) wavelets in potential field analysis with emphasis on the gravity field of the Earth. Many examples are given for practical application of these tools; to support the text exercises and demonstrations are available on the Web.

Book Description
This volume arises from the NATO Advanced Research Workshop (ARW) on 'North African Cretaceous rudist and coral formations and their contributions to carbonate platform development , which was held in Tunisia, on 13-18 May, 2002. It was convened by M. El Hedi Negra (Universite 7 Novembre de Carthage, now Universite de Tunis El Manar, Tunisia) and Eulalia Gili (Universitat Autonoma de Barcelona, Spain). The aims of the ARW were: (1) to review and critically assess currently available data on rudist/coral formations in North African Cretaceous carbonate platforms, and their correlations, and to integrate these data with other studies around the Mediterranean; (2) to place the findings in a global context, noting both similarities with other regions of platform development as well as local differences, and (3) exploring possible reasons for these; and to help promote the creation of a vibrant peri-Mediterranean collaborative research community, embracing researchers from the entire region, to carry forward this ambitious research programme. Twenty-two presentations (oral and poster) provided both topical reviews (covering rudist evolution, and ecology, mineralogical changes, applications of strontium isotope, and graphic correlation methods, and platform typology) as well as regional syntheses (Tunisian reservoirs, Moroccan platform history, Tunisian platforms and rudist/coral facies, Algerian platforms, and Egyptian platforms). Fifteen of these presentations are expanded here as papers. The workshop was attended by 24 academic staff, 4 geologists from the oil industry, plus several observers and students.

Book Description
These proceedings record the results of climate change in many areas which are hyper-arid deserts today but which, almost cyclically, at intervals of thousands or even hundreds of thousands of years, have had a much more humid climate.

Book Description
Modern shallow-water carbonate systems commonly display a complex pattern of juxtaposed depositional environments with a patchy facies distribution (facies mo saics). On ancient carbonate platforms, the reconstruction of lateral facies distribution is often hampered not only by discontinuous outcrop but also by lack of suffi ciently high time resolution. This case study from the Oxfordian (Late Jurassic) of the Swiss Jura Mountains demonstrates a way to improve the temporal and spatial resolution for the interpretation of carbonate rocks. Sequence-stratigraphic and cyclostratigraphic analyses have been performed that provide a basis for defi ning depositional sequences, which formed through sea-level changes that were induced by the 400-, 100- and 20-kyr orbital cycles. On the 100-kyr scale, sequence boundaries are well developed and can be correlated between sections. However, identifi cation and correlation of sequences related to the 20-kyr cycle may be diffi cult if local processes overprinted the record of orbitally controlled sea-level changes. The reconstruction of facies distribution along selected time lines gives a dynamic picture of platform evolution with time steps of a few ten thousand years and helps to interpret the controlling factors such as differential subsidence, low-amplitude eustatic sea-level fl uctuations, climate and ecology of the carbonate-producing organisms. Reefs and ooid shoals developed preferentially on topographic highs and thus accentuated platform morphology. Siliciclastics were shed onto the platform during sea-level falls and increased rainfall in the hinterland; their distribution was controlled by platform morphology. Siliciclastics and associated nutrients hindered carbonate production and thus indirectly infl uenced platform morphology. In addition to these controls, random processes acted on the smaller-scale facies relationships. Sedimentation rates can be estimated for each facies type over time spans of 10- 0 kyr. They.

Book Description
Periplatform slope sediments from the Bahamas serve as an example for a small-scale sedimentologic record of environmental changes. Carbonate platforms react sensitively to sea-level fluctuations. Therefore, sediments deposited on the slope during lowstands differ in composition from highstand deposits. A second focus is the early diagenetic alteration and cementation of these sediments with their high diagenetic potential. This book contributes to and discusses new developments in carbonate sedimentology such as the concepts of highstand shedding and early burial diagenesis, which also have an impact on reservoir studies.
