Abstract
The objective of the present study is to promote the exploration of volcanic domes of rhyolitic to dacitic composition associated with Au-Ag (Pb-Zn) mineralization, mainly where there is little evidence of structures and especially where they do not report significant grades in gold, silver, lead or zinc; except in volatile elements, trace elements and rare earths, where it is often not given due importance.
 The main lineaments of the Shila-Paula mining district are of an Andean NW-SE strike that generate E-W orientation tensions, with this system being the main one because it hosts known economic mineralization in the mining district. In addition, the important mineralized domes in the Shila-Paula mining district are related to hydrothermal alteration of the High Sulphidation (HS) type, with sub-outcropping structures of quartz-alunite composition, grading to argillic and finally distal to propylitic.
