Petrographic observations and simple physical tests reveal the predominance of weakly lithified smectitic claystones, characterized by high plasticity and expansive behavior upon contact with water, and associated with accessory minerals such as quartz, iron oxides, and traces of pyrite. These properties indicate a significant moisture retention capacity and potential for improving the physical properties of soils. Additionally, the relationship between the hydric behavior of these clays and local climatic conditions is discussed, highlighting their relevance as a sustainable geological resource for agricultural applications under conditions of climate variability.
