Introduction to special section on the California-Arizona crustal transect: Part II Introduction to special section on the California-Arizona crustal transect: Part II
In May 1988, a multidisciplinary conference was held in Flagstaff, Arizona, to synthesize recent research on the crustal structural and evolution of a transect across the southern Cordillera. This transect extends from the southern Colorado Plateau southwestward across the Arizona Transition Zone, through the Basin and Range province in the Mojave and Sonoran deserts, to the San Andreas...

The 40Ar/39Ar thermochronology of the eastern Mojave Desert, California, and adjacent western Arizona with implications for the evolution of metamorphic core complexes The 40Ar/39Ar thermochronology of the eastern Mojave Desert, California, and adjacent western Arizona with implications for the evolution of metamorphic core complexes
Mesozoic thickening and Cenozoic extension resulted in the juxtaposition of upper and middle crustal rocks in the eastern Mojave Desert, southeastern California and western Arizona. The application of 40Ar/39Ar thermochronology to rocks in this region provides information about the timing and nature of thrusting, plutonism, metamorphism, denudation, and detachment faulting. The 40Ar/39Ar...

The San Andreas Fault System, California The San Andreas Fault System, California
Maps of northern and southern California printed on flyleaf inside front cover and on adjacent pages show faults that have had displacement within the past 2 million years. Those that have had displacement within historical time are shown in red. Bands of red tint emphasize zones of historical displacement; bands of orange tint emphasize major faults that have had Quaternary displacement...

Program to prepare standard figures for grade-tonnage models on a Macintosh Program to prepare standard figures for grade-tonnage models on a Macintosh
Grade-tonnage models are frequency distributions of deposit tonnage and grades of mineral deposits of a specific type. The program described here allows users to prepare standard figures of grade and tonnage distributions and display the deposit name associated with any of the data points. Titles and scales appropriate for most deposit types are plotted automatically for tonnage, Cu, Ni...

Coal and peat in the sub-Saharan region of Africa: alternative energy options? Coal and peat in the sub-Saharan region of Africa: alternative energy options?
Increased energy demand as a result of growth in population, trends to sedentation and urbanization, and the desire for improvement in living standards, coupled with apparent climatic changes, are reducing fuelwood availability and contributing to deforestation and desertification in the sub‐Saharan countries. In 14 of those countries, the transport, industrial, and electric power...
