Well known is the metallogenetic provinciality of the Central Andes evidenced by the presence of belts, subparallel to the orogen, carrying different metallic associations of mainly hydrothermal origin, as well as the numerous mining resources and deposits associated with porphyry and shallower volcanic systems in the Flat Slab segment. However, little is known about the role of the shallow volcanic processes and the deeper petrogenetic factors that could have influenced a given metal association to predominate over another, as well as the knowledge of the mechanisms that occur in the late-magmatic stages, in the magmatic-hydrothermal transition and in the porphyry-epithermal transition of these systems. Even less has been explored the behavior of strategic elements (e.g., Li, B, etc) in the magma or its sources. The control that the petrogenetic and evolutionary processes exert on the concentration of metals of economic interest in the magma before its final enrichment has been, consequently, traditionally little approached in this zone. This special volume of the JSAES aims to concentrate new contributions, as well as regional reviews in the Central Andes, on the relationship between magmatic processes and metallogenesis, either from the perspective of petrology, geochemistry and field geology, or also relevant mineralogical studies (including ore minerals) that lead to a better understanding of the magmatic-hydrothermal connection in these segments of the Andes. Researchers who may be interested in participating in this special issue are invited to send the titles of papers that could potentially be included in the volume after peer-review process. Pablo J.
