The architecture and mechanics of an orogen can be understood in terms of a system of
collages that are characterized by a complex assemblage of multiple components, but the …

Integration of regional stratigraphic relationships with data on sediment accumulation,
provenance, paleodrainage, and deformation timing enables a reconstruction of Mesozoic …

Construction of the Andes has been governed largely by fluctuating contractional, neutral,
and extensional tectonic regimes during differing degrees of mechanical coupling along the …

Tracing the closure of oceans with irregular margins and the formation of an orocline are
crucial for understanding plate reconstruction and continental assembly. The eastern …

As subducting plates reach the base of the upper mantle, some appear to flatten and
stagnate, while others seemingly go through unimpeded. This variable resistance to slab …

As the archetype of mountain building in subduction zones, the Central Andes has
constituted an excellent example for investigating mountain-building processes for decades …

Accurate spatial models of tectonic plates and geological terranes are important for
analyzing and interpreting a wide variety of geoscientific data and developing compositional …

We present a tomographic model of the crust, upper mantle and transition zone beneath the
South Atlantic, South America and Africa. Taking advantage of the recent growth in …

In continental-margin subduction zones, basalt magmas spawned in the mantle interact with
the crust to produce a broad spectrum of volcanic arc associations. A distinct style of very …

An assessment of the intrinsic aquifer vulnerability of South America is presented. The
outcomes represent the potential sensitivity of natural aquifers to leaching of dissolved …
