The book is splendidly illustrated with 122 text figures, an extensive bibliography, index, together with a set of biogeographic maps illustrating continental and terrain outlines from the mid-Cambrian to the Recent. University students (both advanced undergraduate and graduate level) will find it an excellent text book. For professionals in Biogeography this is a convenient reference work.
⧫ 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It contains numerous unpublished, accurate radioisotopic dates of volcano-sedimentary layers interbedded in fossiliferous marine and continental Miocene sequences representing Mediterranean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.
This work shows the great diversity and usefulness of this interesting class of organisms which are small bivalved aquatic crustaceans that occupy both marine and nonmarine environments. Many are characteristic of estuarine and other tidal habitats, but only a few occupy hypersaline waters. One or two kinds are found in wet soils, or in leaf or flower cups in tropical rain forests. A few live in caves and others are commensal in gills of fish and other aquatic animals. Micropaleontologists have found their shells in many types of sedimentary rocks and have used them for stratigraphic and paleoenvironmental interpretations.
Their relatively rapid rates of evolution have made them useful in subsurface stratigraphy and their sensitivity to environmental changes has provided a means of recognizing variations in rock facies. In nonmarine aquatic rocks they are commonly the most easily recoverable microfossils, and have been widely used in petroleum exploration, notably in China, Russia, Brazil and the western United States.
Paradox, as defined in a dictionary, is a statement contrary to accepted opinion. That a broad discussion of paradoxes is fruitful for the advancement of science in general, and geosciences in particular, has been amply demonstrated by Professor Hsu throughout his distinguished career. Not only has he propelled the geoscience community forward with his controversial statements, a number of his former students, who are currently in key positions at universities and in industry, are influencing in a similar open minded way the present day thinking. The wide scope this reasoning encompasses is demonstrated by the contributions to this book, delineating paradoxes and problems in the fields of tectonics, basic and applied geosciences, petrology, paleoceanography, paleoclimatology and paleogeography, kinematics and modelling.
Frisch, Meschede, and Blakey answer all these questions and more through the presentation and explanation of the geo-dynamic processes upon which the theory of continental drift is based and which have lead to the concept of plate tectonics.
