Caracterización petrográfica y mineralógica mediante técnicas de microscopia óptica de vetas epitermales en la parroquia El Porvenir del Carmen

Abstract

Abstract: This research characterizes an epithermal deposit in the El Porvenir del Carmen parish, an area of high interest for mineral exploration. The general objective was to analyze the geological, structural, and mineralogical conditions of the deposit to understand its hydrothermal evolution and mineral potential, linking these variables with the environmental chemical response. The methodology was descriptive and experimental, combining geological field surveys with laboratory techniques such as X-ray fluorescence and X-ray diffraction. The most significant result identified an intermediate-sulfidation epithermal system, where the chemical interaction between hydrothermal fluids and the protolith low-grade schist was the determining factor for copper sulfide precipitation in a tectonically controlled environment. It is concluded that the paragenetic evolution, from a primary stage to supergene enrichment, confirms that the system underwent multiple pulses of activity, consolidating this deposit as a high-precision geological model for future technical exploration campaigns in the region.
