Resumen
El Cerro Totoral compuesto principalmente de roca granodiorita, es uno de los principales exponentes en cuanto a su posible aplicación como roca ornamental. Los análisis preliminares se concentraron en factores estructurales que puedan influir en la blocometria de este posible yacimiento, puesto que la explotación de este tipo de rocas se la realiza mediante la extracción de bloques.
Se realizaron diferentes mapas con el objetivo principal de determinar las diferentes estructuras que influyan directamente al Cerro Totoral, mediante recopilación de información de campo se logró cartografiar un mapa geológico temático del área de estudio.
La información obtenida en el campo se sintetizo obteniendo 2 puntos con mayores perspectivas mineras de las cuales se les aplicó la metodología de “valoración de áreas canterables” definiendo un punto con mayor potencial minero, siendo el más idóneo para su análisis estructural.
Los análisis estructurales realizados en el sector resultante, arrojaron una negativa calidad blocometrica, determinándola como no idóneo para su explotación como roca ornamental; sin embargo la granodiorita posee una muy buena homogeneidad en cuanto a su textura por lo cual podría ser apta para su uso como adoquín, losetas e inclusive los bloques encontrados en las faldas del Cerro Totoral, si fueran pulidos pueden ser usados como roca decorativa.
La metodología aplicada en este proyecto, puede ser replicado en diferentes prospecciones de rocas graníticas como roca ornamental, puesto que aún se desconocen los diferentes yacimientos de este tipo que se encuentran en nuestro país.
The Cerro Totoral composed mainly of granodiorite rock, is one of the main exponents in its possible application as ornamental rock. The preliminary analyzes focused on structural factors that could influence the blocometry of this possible deposit, since the exploitation of this type of rocks is done by the extraction of blocks. Different maps were made with the main objective of determining the different structures that directly influence the Cerro Totoral, through the compilation of field information it was possible to map a thematic geological map of the study area. The information obtained in the field was synthesized obtaining 2 points with greater mining prospects, which were applied the methodology of "valuation of eligible areas" defining a point with greater mining potential, being the most suitable for its structural analysis. The structural analyzes carried out in the resulting sector showed negative blocometric quality, determining it not suitable for exploitation as ornamental rock; However the granodiorite has a very good homogeneity in its texture so it could be suitable for use as cobblestone, tiles and even the blocks found in the skirts of Cerro Totoral, if polished can be used as decorative rock. The methodology applied in this project, can be replicated in different exploration of granite rocks as ornamental rock, since the different deposits of this type that are in our country are still unknown.
