Abstract EN
Purísima-Rumicruz district consists of several polymetallic veins, rich in copper and lead.
The veins have a breccia texture and are located in shear bands, with locally high concentrations of sulfides in a carbonatic gangue.
The host rock of the veins consists of a black shale sequence with thin levels of fine sands, with a low degree of metamorphism, and corresponds to the Acoite formation (Lower Ordovician).
The depositional environment was an open clastic platform where storm processes prevailed.
An exploratory program using induced polarization and resistivity with the dipole-dipole method was carried out with the objective of establishing geoelectric anomalies in depth, which would permit the identification of exploratory targets.
The group of veins was divided into three sectors: Purísima, El Brechón, and La Nueva.
Low-resistivity values correspond to faulty zones, some of which are related to surface veins.
The presence of diagenetic pyrite in the shales of Acoite formation considerably increases background chargeability (induced polarization) values.
However, small chargeability anomalies associated to low-resistivity values represent exploratory targets for the Purísima-Rumicruz district.
