Porphyry systems supply most copper and significant gold to our economy. Recent studies indicate that they are frequently associated with high Sr/Y magmatic rocks, but the meaning of this association remains elusive. Understanding between rocks porphyry-type deposits is essential develop genetic models can be used for exploration purposes. Here we present results on a Pleistocene volcano Ecuador highlight behaviour in magmas variable (but generally high) values. We provide indirect evidence...
The origin of andesite is an important issue in petrology because the main eruptive product at convergent margins, corresponds to average crustal composition and often associated with major Cu–Au mineralization. In this study we present petrographic, mineralogical, geochemical isotopic data for basaltic andesites latest Pleistocene Pilavo volcano, one most frontal volcanoes Ecuadorian Quaternary arc, situated upon thick (30–50 km) mafic crust composed accreted Cretaceous oceanic plateau...
High-Mg diorites enriched in incompatible elements and their extrusive equivalents are rare subduction-related rock types that have been found modern arc settings Late Archean sequences, where they associated with trondhjemite–tonalite–granodiorite (TTG) suites. rocks these geochemical features known as sanukitoids and, despite limited abundance, considered to be the indicators of onset plate tectonics because similarities high-Mg andesites diorites. Understanding genesis sanukitoid is thus...
Mining and petroleum production are the source of many elements base materials fundamental for our modern way life. The flip side these keystone industries is environmental degradation they can cause if not properly managed. Metallic mining contaminate local ecosystem with sediments, chemicals used in industrial processes heavy metals, part metallic ore or oil reservoir. objective this project was to analyze spatial distribution presence different potentially hazardous that make up deposits...
Abstract The Ecuadorian Quaternary volcanic arc is characterized by about 60 volcanoes many of which are active or potentially active. This activity the result subduction processes Nazca Plate beneath north‐western part South America. geochemical signature discharged fluids from these systems gives an important contribution to comprehension in South‐American region. In this work, we present first systematic characterization entire on basis chemical and isotopic composition 56 samples thermal...
We present a data set on the geochemical and isotopic composition of mineralized porphyry intrusions, se- riate arc volcanic formations spatially associated with late Oligocene to Miocene, porphyry- related ore deposits in Ecuador. Our aim is constrain petrogenetic evolution these magmas, evaluate geodynamic tectonic impact factors magmatism, explore metallogenic signifi- cance parameters. distinguish four groups investigated magmatic centers, indicating dif- ferent paths low- high-pressure...
Tectonic models of the Early Cretaceous Andean margin in Ecuador are hindered by a paucity accurate crystallisation ages igneous rocks. The Alao Arc, situated on western flank Cordillera Real Ecuador, is mainly composed submarine altered basalts to andesites, and most deformed areas frequently modified greenschist metamorphism. To improve our knowledge evolution northern Andes prior accretion Caribbean Large Igneous Province we attempt constrain tectonic origin age arc's volcanic rocks,...
La cuenca Oriente (Cretácico-Cenozoico tardío) es una de las más complejas y atractivas cuencas sedimentarias antepaís los Andes septentrionales. Está constituida por diversos ciclos tectónicos sedimentarios, desarrollada sobre un basamento Precámbrico. Con el fin evaluar potencial geotérmico teórico usos potenciales del calor en la cuenca, datos temperaturas fondo pozos (BHT) 1683 petroleros profundos, distribuidos 202 campos individuales, han sido ploteados mapa georreferenciado, cubriendo...
