Quaternary tectonics at the Andean backarc at the latitude of the Tromen volcano (37°S)
Recent studies focalized in the vicinity of the Tromen volcano, in the northern Neuquén Province, indicate the presence of Quaternary structures. In particular, a detailed analysis on its western volcanic flank shows broad neotectonic deformational zones, whose only frontal sector had been previousl...
