Then it is realized and specified by three major constituent parts, i. e. (1)dynamical attributes of ore deposits, (2)fields of oregeology and (3) evolution of ore-forming systems.
Based on ore-forming condition and oregeology, ore-controlling factors are analyzed. It is suggested that the deposit is controlled by ore-hosting strata, ductile-brittle shear zone and magmatism.
Escondida means "hidden" in Spanish, and it refers to the fact that the copper ore body was buried beneath hundreds of meters of barren rock, and the surface geology gave no signs of its presence.
