This research investigates the origin and relationship between adakites and non-adakitic magmas found at Los Espinos Volcano (LEV), situated within the Michoacán-Guanajuato Volcanic Field (MGVF) in Mexico. LEV consists of a younger phreatomagmatic tuff cone (LETC) with adakitic features, overlaying two pre-tuff cone units (PTC) made of a lava flow and a scoria cone remnant, both of calc-alkaline composition. The primary objective is to assess whether the shift from calc-alkaline to adakitic comp
