Terra Nova, 23, 26–34, 2011 Abstract The timing of orogeny in the northern Andes and the
mechanism driving it are still debated. We have studied the age, composition and …

A Paleogene conglomeratic-sandy succession preserves the complex record of arc-
continent collision, orogen collapse and basin opening, followed by inversion related to …

Tectonics, climate, and lithology are the three main factors controlling the generation and
transfer of sediments as well as their textural and compositional signatures. In this paper, we …

As is common in suture zones, widespread high‐pressure rocks in the Caribbean region
reached eclogite facies conditions close to ultrahigh‐pressure metamorphism. Besides …

Exhumed serpentinites are fragments of ancient oceanic lithosphere or mantle wedge that
record deep fluid‐rock interactions and metasomatic processes. While common in suture …

The Siuna Serpentinite Mélange (SSM) is a subduction-zone-related complex that contains
diverse blocks of igneous and sedimentary origin, overprinted by various metamorphic …

Single-shot laser ablation split stream (SS-LASS) petrochronology offers spatial resolution
of< 1 μm per (surface) analysis. This enables the technique to interrogate metamorphic …

The onset of subduction in the Caribbean Plate under the South American Plate allowed the
development of an Active Continental Margin; the age of onset, the mechanism and the …

Abstract The Guajira Arch is located in the northernmost portion of South America and holds
the record of several stages of magmatism and metamorphism. We performed LA-ICP-MS U …

Chromitite bodies can be found within ophiolitic mantle sections in three locations in
Colombia: Medellín, Planeta Rica, and La Guajira. These chromitites are typically massive …
