Abstract

In the context of the Cajamarca region in 2024, the main objective of this investigation is to provide a solid basis for assessing the suitability of the sandstones from the Casa Blanca deposit in Cajamarca, for use in the construction industry. To date, mineragraphic and crystallographic studies have not been carried out in this area, which has led to the selection of low-quality materials and durability issues in the structures. This study focuses specifically on the sandstones present in the area. It has been complemented by Vertical Electrical Sounding (resistivity) studies to determine the depth of the sandstone bank and assess its profitability. In addition, macroscopic, microscopic and granulometry analyses were carried out to characterize the physical and mineralogical properties. The results reveal the key characteristics of these sandstones, which allowed determining their quality and suitability for construction. This discovery has crucial implications for infrastructure safety and resource sustainability, highlighting the need to implement quality control measures in the selection of materials.
