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.
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.
The book introduces the topic of geochemical modeling of fluids in subsurface and hydrothermal systems. The intention is to serve as a textbook for graduate students in aqueous, environmental and groundwater geochemistry, despite the fact that its focus is on the special topic of geochemistry in hydrothermal systems, it also provides new insights for experienced researchers with respect to the topic of reactive transport. The overall purpose is to give the reader an understanding of the processes that control the chemical composition of waters in hydrothermal systems and to highlight the interfaces between chemistry, geothermics and hydrogeology. From the reviews: "..is a nice, compact introduction to the principles of modeling coupled fluid flow and fluid-mineral reactions in active geothermal systems, as used for heating and electricity generation."

Stephan Mueller Special Publication Series (SMSPS) is an international, interdisciplinary book series for publication of collections of extended, but self-contained communications in the Earth, planetary and solar system sciences, published by the European Geosciences Union in books and on WWW. The collections may include papers presented at scientific meetings (proceedings) or articles on a well defined topic compiled by individual editors or organizations (special publications). Stephan Mueller Special Publication Series (SMSPS) is published by the Copernicus GmbH (Copernicus Publications) on behalf of the European Geosciences Union (EGU).
"The Ediacaran-Ordovician of East Laurentia is a product of the 12th International Symposium on the Cambrian System held in eastern New York and western Vermont in July and August of 2007. This well illustrated, important contribution includes a new regional summary of Ediacaran-Ordovician epeirogeny, tectonics, eustasy, and oceanic oxygenation along the New York Promontory, a detailed week-long field trip guide, and abstracts of oral and poster presentations of international studies on the Cambrian Period."--Publisher's description.
Evidence for Paleoclimatic Changes from Mineral, Trace-Metal and Pollen Data
Author: Saulo Rodrigues-Filho
Mineralogical-sedimentological and geochemical investigations in combination with pollen data of a 12.7-m-long dated sediment core from Lake Silvana, SE Brazil, permit the reconstruction of the climatic history over the past 10,000 years. The lowermost section (I) reflects a coarse paleosol-type sediment with abundant plant debris and rootlets; pollen indicates grassland vegetation. Section II represents fine-grained lake sediments; pollen indicates a savanna-like vegetation. Section III represents a pollen-free, coarse-grained allogenic sediment deposited under high transportation energy (increased precipitation). Section IV, a greenish sequence with increasing C content towards the top, has a pollen spectrum of present-day vegetation (semideciduous forest). The different sediment sections show a connection with erosional phases in the catchment of the lake, based on mineralogy and geochemistry, which are a response to climate development.
