The central and southern Coast Ranges of California coincide with the broad Pacific–North
American plate boundary. The ranges formed during the transform regime, but show little …

▪ Abstract The migration of the Mendocino triple junction through central and northern
California over the past 25–30 million years has led to a profound change in plate …

ABSTRACT The Los Angeles basin formed in late Neogene time on a continental margin
previously shaped by Cretaceous and early Paleogene subduction, Paleogene terrane …

Four maps are presented here that show the location and extent of magmatic fields between
eastern Alaska and northern Mexico during the successive time intervals of 55–40, 40–25 …

The addition of crustal material to the base of the continental crust, crustal underplating, may
play an important role in the evolution of the continental crust and lithosphere. We have …

A two-layer (crust and upper mantle), finite difference steady-state thermomechanical model
of a long-lived (several million years) lithospheric strike-slip fault is presented, and its …

For thermal considerations, the lithosphere is defined as the outer layer of the Earth in which
heat transfer is dominated by conduction. Low density continental crust caps the continental …

The presence of the San Andreas fault was dramatically brought to the attention of the world
on April 18, 1906, when displacement along the fault resulted in the great San Francisco …

The Altiplano-Puna Volcanic Complex (APVC) in the central Andes is the product of an
ignimbrite “flare-up” of world class proportions (de Silva, 1989). The region has been the site …

We have examined shear-wave splitting in teleseismic shear waves (SKS, SKKS, S) from 15
stations in the western United States, based on analysis of 123 records from 67 events. The …
