Abstract

The present research is located in the Republic of Ecuador between latitudes 3°20’S and 4°00’S, was developed with the objective to proposing potentially prospective targets, for which geological, geochemical and geophysical data from the area were analyzed. From the geochemical information PRODEMINCA project (stream sediments sampling) and applying the Ordinary Kriging method, results were genered for elements: Ag, As, Au, Cu, Co, Cd, Cr, Fe, Ni, Pb, Sb V y Zn, defining 7 potentially prospective targets were defined, which have typical characteristics of porphyry and epithermal systems. Magnetic data processing delimited zones of susceptibility magnetic, zones were delimited, associated with different types of rocks and regional faults. In this work, the metallogenic belt Machala was defined by means of geochemical and geophysical anomalies and the structural geology.
