The thin-skin Sevier and thick-skin Laramide belts of the North American Cordillera provide
a long-term record of the interrelations between evolving styles of mountain building and …

Isotopic and trace element analysis of zircons can provide reliable and robust estimates of
age, compositions of coexisting minerals and melts, and constraints on the genesis and …

A long-standing goal in high-precision and high-accuracy U–Pb zircon geochronology is the
total elimination of discordance caused by Pb loss. In theory, this is fairly straightforward, but …

Geochronological, structural, and sedimentological data provide the basis for a regional
synthesis of the evolution of the Cordilleran retroarc thrust belt and foreland basin system in …

A new model for the earliest stages in the evolution of subduction zones is developed from
recent geologic studies of the Izu-Bonin-Mariana (IBM) arc system and then applied to Late …

This study includes a compilation of about one hundred estimates of volumetric rates of
magma emplacement and volcanic output that are average rates for durations of igneous …

The calc-alkaline granitoids of the central Sierra Nevada batholith are associated with
abundant mafic rocks. These include both country-rock xenoliths and mafic magmatic …

Useful U–Pb isotopic data may be obtained from sphene (or titanite, CaTiSiO5) because:(1)
it is a widespread accessory mineral,(2) it can incorporate uranium in its structure, and (3) it …

Subduction erosion occurs at all convergent plate boundaries, even if they are also
accretionary margins. Frontal subduction erosion results from a combination of erosion and …

The Franciscan Complex of California records over 150 million years of continuous E-
dipping subduction that terminated with conversion to a dextral transform plate boundary …
