The Middle-Late Jurassic mafic dike swarms of central Chile between 33º and 33º45'S register the tectonic activity of the contemporaneous arc represented by the Coastal batholith. These dike swarms evidence alternate episodes of transtension and transpre...

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 ...

One of the most critical stages in fault-slip data stress analysis is separating the fault data into homogeneous subsets and selecting a suitable analysis method for each subset. A basic assumption in stress tensor computations is that fault activations ...

Abstract. The main known Brazilian continental faults with a length of more than 100 km were summarized in the text. An attempt to describe their characteristics in the frame of the regional tectonic organization and evolution instead of just classifying...
