The mineralization of the Andes is a result of the deformation of the Nazca and South American plates, related to geological structures as a result of Andean deformation, whose study of the geometry of the mineralized bodies depend largely tectonic good knowledge reservoir area, being necessary to apply special methods and tectonic microtectónicos that lead to determine the tectonic model of a region and its consequent relationship with the mineralized structures. For the application of the method of determining the geometry of filoneanos sites, it is taking the example of the veins of the Mining Corporation Take Hand, located on the axis of the Cordillera Blanca Huascaran Park, Province of Carhuaz, Ancash, where we make a tectonic study and complete microtectónico, to determine the extent of the veins. The method consists of first determining the geological macrostructure through regi...

The Andean Cordillera was formed at the forefront of the South American Plate as a consequence of the collision of this Plate with the Nazca Plate. The Cordillera was later progressively deformed by subsequent tectonic events. The associated stresses acted on the volume of lithosphere between the Peru-Chile Trench on the west, and, the Brazilian Shield on the east. The base of the lithosphere at the root of the Andes takes the form of a surface concave upwards, a consequence of the tectonics and the weight of the lithosphere. This root sinks into the fluids of the Upper Mantle favoring a lithosphere thickness of 200 Km, plus the 7 Km elevation above sea level of the Central Andes. The new tectonic model herein proposed considers the division of the Nazca Plate into three segments: 1) Southern Nazca Plate, 2) Central Nazca Plate, 3) Northern Nazca Plate. Furthermore, it is proposed that t...

La teoría de Briam Brady, que a continuación se discute, ha sido presentada por carta de fecha 25 de agosto de 1977 al Sr. L. C. Pakiser, jefe activo de las ramas de sismología y estructura de la corteza, de la Geological Survey de los Estados Unidos. Está basada en el análisis estadístico de la información telesísimica de los eventos producidos entre 1962-74 en la zona del Perú Central. Esta información ha sido interpretada en términos de la Teoría de las Inclusiones en zonas de silencio sísmico, que, mediante la utilización de fórmulas automáticas del cálculo de probabilidades, el Dr. Brady, calcula el área y tiempo del probable sismo, llegando a la conclusión que la región comprendida entre Lima-Nazca y zócalo continental (mar), puede encontrarse a la actualidad en una etapa de preparación de un futuro terremoto de características catastróficas.
