| Abstract | Mesozoic volcanic rocks outcrop in North Patagonian Andes, near Trevelin locality, Chubut province, Argentina. Basaltic andesites and basalts with porphyritic to aphyric textures with calcium plagioclase, clinopyroxene, and olivine phenocrysts are the most common rocks. Their groundmass texture is felty to intergranular. These units are affected by a hydrothermal alteration that replaced their phenocrystals and groundmass and fi lled veins, veinlets and amygdales. Minerals were analyzed by conventional microscopy, scanning electron microscopy-energy dispersive scan, X- ray diffraction, infrared spectroscopy, and fl uid inclusions microthermometry.
