Tertiary Volcanic Belt
Tags: cretaceous paleogene paleozoic
Description:
The volcanic belt has been developed on top of older, mainly sedimentary, Paleozoic and Mesozoic units, which in general lie to the southwest and northeast of the volcanic belt. Northwest-trending, beltparallel zones of Cretaceous to Tertiary age felsic intrusives lie to the southwest and northeast of the central part of the Tertiary Volcanic Belt.
Dominant structural trends are northeast, northwest and to a lesser extent north-south. Base metal mineralization generally occurs associated with the intrusives as porphyry and a skarn-type mineralization. Gold-silver mineralization, usually of the high or low sulphidation epithermal type, tends to occur within a northwest-trending, belt-parallel zone, centrally located in the Tertiary Volcanic Belt. Examples are the Madrigal, Caylloma,
Suckuytan, Orcopampa, Poracota, Ares and Arcata mines and prospects to the south, and Santa Rose and Selene to the northwest of Liam.
