Determining the absolute duration of magmatic-hydrothermal events leading to formation porphyry systems (i.e., including copper, skarn, and epithermal deposits) is one key questions in ore geology. This so because instrumental development genetic models necessary explore a category mineral deposits that provide most copper significant amounts base precious metals our economy. The problem determining has been addressed through thermal modeling cooling intrusions time needed precipitate...

We investigated the Neoproterozoic–early Paleozoic evolution of Gondwanan margin north-central Andes by employing U-Pb zircon geochronology in Eastern Cordilleras Peru and Ecuador using a combination laser-ablation–inductively coupled plasma–mass spectrometry detrital analysis dating syn- post-tectonic intrusive rocks thermal ionization mass ion microprobe. The majority samples exhibits prominent peaks ranges 0.45–0.65 Ga 0.9–1.3 Ga, with minimal older detritus from Amazonian craton. These...

Abstract The determination of accurate and precise ages for the timing collision between oceanic plateaus continental crust requires an understanding how indenting buttressing plates respond to collision. We present geochronological, thermochronological, geochemical isotopic analyses magmatic rocks from Ecuadorian Andes, which relate Late Cretaceous Caribbean Plateau Great Arc sequence with NW South America. cessation subduction magmatism during 65–64 Ma beneath eastern edge was synchronous...
The topographically prominent Sierra Nevada de Santa Marta forms part of a faulted block continental crust located along the northern boundary South American Plate, hosts highest elevation in world (∼5.75 km) whose local base is at sea level, and juxtaposes oceanic plateau rocks Caribbean Plate. Quantification amount timing exhumation constrains interpretations history plate boundary, driving forces rock uplift active margin. Province southernmost exhumed elevated rates (≥0.2 Km/My) during...
