Book Description
Based on the Tenth International Basement Tectonics Conference held at the University of Minnesota-Duluth in August 1992, this volume contains 19 papers, 13 of which focus on the Middle Proterozoic Midcontinent Rift. An introductory essay discussing the Middle Proterozoic to Cambrian rifting in central North America is followed by contributions addressing topics including the Midcontinent Rift in Michigan and Minnesota, the Port Coldwell veins of northern Ontario, and petrography and sedimentation in the western Lake Superior region. The last five papers deal with the pre-Mount Simon basins of Ohio, the English Graben and the newly proposed East Continent Rift Complex, the Reelfoot Rift/Rough Creek Graben in the evolution of the Illinois Basin, and the A-type sheet granites in the Oklahoma Aulacogen of Cambrian age. Bandw illustrations. Annotation copyrighted by Book News, Inc., Portland, OR

Book Description
Brings together a series of papers which explore various aspects of the deformation of continental lithosphere, covering different tectonic settings from the Palaeozoic to the present day. These include terrane accretion and juxtaposition, the exhumation of high-pressure terrains, and mechanisms of crustal extension and rifting.

Book Description
In this sequel to the award winning Talking Rocks an earth scientist and an Ojibwe elder travel across Minnesota exploring the ancient rocks that make up a large part of that state.As the geologist describes how these rocks formed and brings to life the ancient worlds they created, the elder, through Native American stories, oral history, culture, and science illustrates how his people had an intimate understanding of,and respect for, these ancient rocks and the land they gave shape to.Traveling from Ely, Grand Portage, Gunflint Lake, and Isle Royale in the northern part of the state south to Jeffers, Mor¬ton, and Blue Mounds State Park the two find themselves discussing such diverse topics as the nature of science, holistic geology, mining, science and spirituality, the legacy of the furtrade, significance of the Little Spirit Tree, and much more. Ancient Earth and the First Ancestors not only tells a fascinating story that spans billions of years, but is also a wonderful chronicle of two people from different cultural and scientific heritages learning to understand, appreciate,and see the value and importance in each other’s way of viewing this land and the planet we all call home.

Book Description
Impact cratering is an important geological process on all solid planetary bodies, and, in the case of Earth, may have had major climatic and biological effects. Most terrestrial impact craters have been erased or modified beyond recognition. However, major impacts throw ejecta over large areas of the Earth's surface. Recognition of these impact ejecta layers can help fill in the gaps in the terrestrial cratering record and at the same time provide direct correlation between major impacts and other geological events, such as climatic changes and mass extinctions. This book provides the first summary of known distal impact ejecta layers

Book Description
The supercontinent-cycle hypothesis attributes planetary-scale episodic tectonic events to an intrinsic self-organizing mode of mantle convection, governed by the buoyancy of continental lithosphere that resists subduction during the closure of old ocean basins, and the consequent reorganization of mantle convection cells leading to the opening of new ocean basins. Characteristic timescales of the cycle are typically 500 to 700 million years. Proposed spatial patterns of cyclicity range from hemispheric (introversion) to antipodal (extroversion), to precisely between those end members (orthoversion). Advances in our understanding can arise from theoretical or numerical modelling, primary data acquisition relevant to continental reconstructions, and spatiotemporal correlations between plate kinematics, geodynamic events and palaeoenvironmental history. The palaeogeographic record of supercontinental tectonics on Earth is still under development. The contributions in this Special Publication provide snapshots in time of these investigations and indicate that Earth’s palaeogeographic record incorporates elements of all three end-member spatial patterns.
