A large, damaging earthquake in 1944 on a blind thrust fault caused 60 cm of surface rupture on the subsidiary La Laja fault and additional unmeasured growth of an associated backlimb fold. Both the fold and fault are c ...

Four multicyclic complex calderas and smaller ignimbrite shields located within the Altiplano Puna Volcanic Complex of the Central Andes (APVC) erupted 13000 km³ of magma within the last 11 Ma. One of the largest and mos ...

A change to a warmer, drier climate beginning as early as 1900 was responsible for triggering a dramatic, rapid retreat of Collier Glacier, Oregon, between 1924 and 1940. Although there was a dramatic decrease in preci ...

The detection of subtle variations in mineral chemistry in zoned hydrothermal alteration associated with the formation of porphyry copper deposits by short-wave infrared spectroscopy and rock chemistry are potentially ...

The sheeted complex of the ~92 Ma Tenpeak pluton, in the Northern Washington Cascades crystalline core, forms a <1.5-km wide zone with a moderate, NE-dip at the SW margin of the pluton. Sheeted magmatic complexes, such a ...

The role of bedrock landslides in the denudation of fluvial catchments has received considerable attention, whereas the relative contribution of deep-seated bedrock landslides to the erosion of glaciated basins is less w ...

This dissertation combines volcanological research of three convergent continental margins. Chapters 1 and 5 are general introductions and conclusions, respectively. Chapter 2 examines the spatiotemporal development of ...

The Salt Range is clearly the active participant in the scenario of the progressive southward migration of the Himalayan thrust front. It extends approximately 180 km ENE along strike and is underlain by salt. This is ma ...

Gravity data along an east-west profile from the Punjab plain of Pakistan to the western border town of Chaman have been incorporated into interpretation of the gross crustal structure underlying the Sulaiman Range. In ...
