The rediscovery of America by the Genovese Christopher Columbus and the conquest of
Mexico by the Spaniards was followed by a more gradual, but equally relentless, occupation of …

Stress estimates as a function of depth are obtained for peridotite xenoliths from the upper
mantle of three types of tectonic environments by applying revised recrystallizedgrain-size …

Left-lateral motion along the North American–Caribbean plate boundary has juxtaposed two
high-pressure–low-temperature (HP-LT) belts from separate Cretaceous collisions. These …

Global Positioning System geodesy and structural analysis of parts of the Aleutian island
chain support the interpretation of forearc migration westward along right-lateral transcurrent …

New experiments on Mt. Burnet dunite have been carried out to evaluate the effects of important
physical parameters on recrystallized-grain size and subgrain size in olivine deforming …

Previous experimental deformation of orthorhombic enstatite at temperatures from 200 to
1000C has produced clinoenstatite; yet, the natural occurrences of clinoenstatite in deformed …

Preferred orientations of olivine have been produced by syntectonic recrystallization in
dunite samples that have been deformed moderately in a general stress field at high …

The Guatemala suture zone is a major east–west left-lateral strike slip boundary that separates
the North American and Caribbean plates in Guatemala. The Motagua fault, the central …

Convergence between the Pacific and North American plates along the Aleutian volcanic
island arc is generally right-oblique; the obliquity increases from 0 in the east to nearly 90 in …

Experiments on Canyon Creck quartzite have been conducted at a constant strain rate of 78•
10 “/sec in the temperature range 6009 to 1050 C and confining pressure interval 4 to 20 kb …
