Examines the structural evolution of the Earth's crust from the Triassic period to the present. The book describes the patterns of distribution, and the composition and accumulation conditions of formations in the various geological periods in all the continents and oceans.
Translated from Russian, this text looks at the development of the earth's crust in the Palaeozoic period and starts from the Vendian to the Late Cambrian period. Moving on to include Ordovician to the mature stage of Caledonian and initial stage of development of Hercynian mobile belts; Silurian-Early Devonian. The completion of development of the Caledonian and early, mature and end stages of the Hercynian mobile belts; the birth of Cimmerian mobile belts and ending with the Palaeozoic.
"This unusual book, published to honor Warren Bell Hamilton, comprises a diverse, cross-disciplinary collection of bold new ideas in Earth and planetary science. This volume is a rich resource for researchers at all levels looking for interesting, unusual, and off-beat ideas to investigate or set as student projects"--
In this Special Paper, Hildebrand and Whalen present a big-picture, paradigm-busting synthesis that examines the tectonic setting, temporal relations, and geochemistry of many plutons within Cretaceous batholithic terranes of the North American Cordillera. In addition to their compelling tectonic synthesis, they argue that most of the batholiths are not products of arc magmatism as commonly believed, but instead were formed by slab failure during and after collision. They show that slab window and Precambrian TTG suites share many geochemical similarities with Cretaceous slab failure rocks. Geochemical and isotopic data indicate that the slab failure magmas were derived dominantly from the mantle and thus have been one of the largest contributors to growth of continental crust. The authors also note that slab failure plutons emplaced into the epizone are commonly associated with Cu-Au porphyries, as well as Li-Cs-Ta pegmatites.
