Closure of the Central American seaway was a local tectonic event with potentially global
biotic and environmental repercussions. We report geochronological (six U/Pb LA‐ICP‐MS …

inferred resource of 35.98 Mt.@ 0.77 g/t Au containing 893,600 oz. Au (including 183,930 …

This paper presents new geological constraints on the collision of southern Central America
with South America, and the resulting deformational episodes that have affected the …

The Central American forearc allows insight into the long-term evolution of the Middle
American margin and possible shifts between accretionary and erosive periods of …

The “subduction initiation rule”(SIR)(Whattam and Stern, 2011) advocates that proto-arc and
forearc complexes preserved in ophiolites and forearcs follow a predictable chemotemporal …

Abstract Cerro Quema (Azuero Peninsula, southwest Panama) is a high-sulfidation
epithermal Au-Cu deposit hosted by a dacite dome complex of the Río Quema Formation …

Abstract The Azuero Peninsula, located in SW Panama, is a region characterized by a long-
lived intra-oceanic subduction zone. Volcanism began in Late Cretaceous time, as the result …

Detailed geologic map** (639 field stations in~ 700 km2) and a~ 50 km-long gravity
survey (142 stations) in the western Azuero Peninsula revealed two faulted and folded …

A review of the bedrock geology of the Isthmus of Panama highlights tectonic deformation—
tilting, bending, and breaking—, as the major controlling factor in the sites and modes of …

Abstract The 70.74 to 70.66 Ma age range for three molybdenite samples accompanying
pyrite-and enargite-bearing assemblages effectively constrains an earliest Maastrichtian …
