Estudo geofísico na Suíte Vauthier - porção nordeste de Dom Pedrito – RS

Abstract

In recent years, a large amount of geophysical data on land and air is being integrated with the geological data in Brazil, in order to detect and analyze discontinuities and boundaries, lithological, serving this way as an aid in the characterization of an area. The region of Dom Pedrito, southern half of the State of Rio Grande do Sul is traditionally known by the occurrences of minerals of copper and gold. This has, over the years, being exploited by large companies and, recently, an intensification in the project scoping for the feasibility of exploitation of the deposits in the assessment. These actions provide for the region's labour, foreign exchange and opportunities in the different areas of study especially in the geophysics. The Project aerogeophysical Project of Rio Grande do Sul, executed in 2010 by the Research Company of Mineral Resources (CPRM), provided geological information, integrated geophysical data on land, consists in the proposal of this research. The main goal is to integrate and interpret geophysical data and geological, featuring features and domains correlate the different geological units, to define lateral limits and depths of the structure, and discontinuities. This extension, is described as a Suite of Sub-Volcanic Vauthier, where are the bodies of the mafic sequence. The integration of geological with geophysical data (models lito-geophysical) and definition of domains, allows the development of theories and hypotheses about the articulation and continuity of structures and features at different levels of depth.
