Bedrock exposed in the northern Laramie Mountains of central Wyoming, U.S.A. records a Paleoarchean through Neoarchean history of magmatism, sedimentation, anatexis, and deformation of a southeastern portion of the Beartooth-Bighorn Magmatic Zone (BBMZ) subdivision of the Wyomin…
The issue of granite petrogenesis plays a key role in our overall understanding of the growth and differentiation of continents, as well as in our ability to unravel the tectonic histories of orogenic belts. Granites are ubiquitous magmatic products found in almost all tectonic …
The NE Pacific Ocean is considered the birthplace of many fundamental ideas for modern plate tectonics theory. In this book the orogenic belts of this region are discussed in a single, internally consistent tectonic concept. Geological information is considered the most reliable…
This book presents an analysis of our current knowledge on the origin of the Earth's continental crust. There are two aspects to consider: tectonic and igneous processes. Tectonic aspects include sedimentary accretion, terrane accretion, and continental collision at continental …
Archean oxidative weathering reactions were likely important O2 sinks that delayed the oxygenation of Earth’s atmosphere, as well as sources of bio-essential trace metals such as Mo to the biosphere. However, the rates of these reactions are difficult to quantify experimentally …
