Abstract

Faults play a major role in the formation and deformation of ore deposits. In particular, the Sto. Tomas II orebody in Padcal, Tuba, Benguet, North Luzon, Philippines, has been intimately associated with faulting events related to the Albian and Sta. Fe Faults. This paper tackles the nature of these faults and their role in mineralization, in the light of new modelling techniques.
