Structure and Evolution
Nevados Casiri consists of four edifices defining a ridge which probably reflects the migration of the magmatic source (Figure 8.1). Three unnamed old cones are aligned E-W, while the youngest cone is to the SE of this ridge. Evidence of Holocene activity is found in two lava flows (L) from the youngest cone which also has a well defined summit crater (SC) . An older massive silicic dome (D) is present to the W of the young cone. Two sulphur mines, Azufreras Gloria and San Luis, have been opened, apparently in acid leached and altered material underlying younger lavas.
