Where iodine is available in formation waters, a modest increase in the I/Cl ratios of mineralizing fluids associated with the quartz veins of Cu porphyry deposits has been observed (Kendrick et al., 2001); perhaps this process may be analogous to the process of io- dine enrichment in the oceanic crust as well as in ultramafic material.

Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineral-laden water (hydrothermal solution).The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma. Other sources of heating that may be involved include energy released by radioactive decay or by faulting of the Earth's crust.

PORPHYRY DEPOSITS - Earth Science

DESCRIPTIVE/GENETIC SYNOPSIS: Au is present in a stockwork of quartz veinlets within subvolcanic diorite, tonalite, and dacite porphyry emplaced in the core or flank of a stratovolcano. Potassic (biotite) and (or) sericitic alteration in the ore zone is locally overprinted from above by alunite-kaoline alteration.

These features are like those in many other Au-rich porphyry systems, and they have also stimulated comparisons with andesite-hosted iron-oxide(-Cu-Au) (IOCG) systems such as Candelaria. At Dos Pobres, as in most Cu-Au-Mo porphyry deposits, Cu-Fe sulfides are deposited with voluminous early quartz veins, magnetite is widespread but minor in
