Abstract

In the present investigation, a topographic map was made based on a scale of 1: 1000, the geology was determined by mapping and sampling, obtaining as geology predominant volcano sediments of continental origin specifically meteorized tobas belonging to the Misahuallí Member of the Chapiza Formation of Jurassic Upper- Cretaceous Inferior. The physical characterization of soil was developed, resulting in a textured soil ranging from clayey to silty-sandy clay, the mineralogy was examined through the microscope, resulting in the presence of Quartz minerals in percentage amounts of 2 to 5 %, Feldspars in 15 to 25%, orthoses of 10 to 20%, Fe minerals as limonite of 15 to 25%, magnetite with an average of 10 to 25% and Galena associated with Sphalerite in a percentage of 10 To 20%. Chemical element analyzes were performed in the laboratory and concentrations below 2 ppm Fe, K less than 5 ppm, Ca concentrations below 10 ppm, Mg less than 10 ppm, and concentrations of Al with lower ranges and Equal to 100 ppm, sometimes exceeding 100 ppm. The concentrations of predominant elements are closely linked to the mineralogical components of the parent rock.
