Cretaceous porphyry copper deposits of northern Chile (28º-29º30? S) are genetically related with dacitic to dioritic porphyries and they represent a still poorly-explored target for Cu resources. The porphyries correspond to stocks distributed into two ...

We present a structural study on the tectonic windows of Giffoni and Campagna, located in the western sector of the southern Apennines (Italy). We analyzed thrusts, folds, and related minor deformation structures. Here, a major in-sequence E-verging thru...

Crustal thickening by horizontal shortening and associated deformation have been broadly considered as
prime mechanisms for mountain building in the Central Andes of western South America. However, timing and structural
style of Andean orogeny in norther...

This paper presents low-temperature thermochronological data and K-Ar fault gouge ages from the Sierra
de San Luis in the Eastern Sierras Pampeanas in order to constrain its low-temperature thermal evolution and exhumation
history. Thermal modelling base...
