In Gonto La valley, southern Tibet, a continuous, planar, ∼10°N dipping detachment horizon juxtaposes Tethyan slates over a footwall of leucogranite that intrudes a S-dipping injection complex layer that I regard as a rotated Southern Tibet Detachment System (STDS) horizon. This…

The arc exhumation hypothesis states that new basalt-rich sources lifted during arc-continent collisions cause atmospheric PCO\sb2 drawdown and global cooling. Drawdown lags the early release of CO\sb2 and ¹⁸⁷Os from uplifted continental margin sediments. It generally precedes r…

Based on 17 months of ethnographic field work on the current exhumation of mass graves from the Spanish Civil War (1936-1939) and subsequent Francisco Franco dictatorship (1939-1975), the dissertation examines the practice of exhuming as a death ritual animated by emotions. A la…

High-pressure-low-temperature (HP -LT ) metamorphic rocks such as blueschist and eclogite are interpreted to mark the location of ancient subduction zones. These rocks are typically interlayered with rocks that either did not experience, or did not record, HP -L T metamorphism. …
