The very well preserved Belingwe Greenstone Belt provides a case study of Archaean crustal evolution, a geological window into the very early evolution of the earth. It contains some of the most interesting Archaean rocks on earth. The Archaean includes about one third of the earth's history, and there is vigorous debate about the early development of life, the evolution of the continents and the oceans, and the formation of mineral deposits. Geological relationships in the belt now form the basis of the Zimbabwe Archaean stratigraphy. Some of the freshest komatiitic volcanic rocks known constrain the chemistry and thermal structure of the early mantle and stromatolitic and well preserved sedimentary rocks provide a record of surface processes.
This volume of nine contributions presents the stratigraphy of the belt, its structure and tectonic setting, the sedimentology of what may be a rift basin, the geochemistry of the freshest Archaean komatiites yet found, and models of the evolution of the region. It is a detailed case study, based on field evidence of what may be the most complete and best preserved greenstone sequences yet found and a key reference work for all interested in the Archaean, whether from an interest in the early Earth or from an economic interest in the Archaean stratigraphic and volcanic controls on mineral deposits. The volume will serve as an ideal case study for undergraduate students interested in the formation and evolution of early crust.

With grants from the Hewlett Packard and Carnegie Foundations, Chris Juzwiak and a growing team of developmental instructors continue to uncover how basic writers learn best, pinpointing what encourages them, what discourages them, and how to serve their learning needs. Stepping Stones reflects the results of these studies with scaffolded exercises and instruction, color-coded parts of speech and writing concepts, and creative activities. With a strong visual appeal and clear explanations, this innovative textbook presents sentence and paragraph patterns so that all students can immediately grasp them, and offers carefully constructed guidance for developing and organizing ideas—-two of the most difficult tasks for developmental students.Award-winning educator, Chris Juzwiak, knows that many basic writing students have experienced failure in the past, but that with the right tools they can also become confident and successful learners.
