Potential of carbonate rocks in Méndez area, Morona Santiago province, Ecuador

Abstract

The study evaluated the geological potential of carbonate rocks in the Méndez region, analyzing their characteristics and possible economic implications. The purpose was to evaluate the characteristics of these rocks as raw materials for the cement industry, applying quantitative methods (percentage determination of present elements and volume) and qualitative methods (textures and petrographic characteristics). The exploration involved lithostratigraphic characterization in the field, as well as an assessment of the quality and quantity of the calcareous material exposed at the surface. Laboratory analyses of calcareous rocks conducted by IIGE indicated high percentages (90,3 – 96,6%) of CaCO₃, moderate (5,34 – 9,89%) SiO₂ values, and low levels of penalizing oxides (< 1%) such as MgO, indicating the high quality of the calcareous rocks in this sector. Furthermore, the geometry of the limestone packages, lateral continuity, apparent thickness and minimal presence of overburden are favorable characteristics for advancing the exploration of this resource.
