MARGIN: 0cm 0cm 0pt" class=MsoNormal>man’,’serif’" lang=EN-US>Tengchong volcano-tectonic area located in southeast Tibetan plateau has experienced frequent magmatism. In order to support selecting site and pilot holes for continental scientific drilling, the authors conducted geophysical investigations in the area from Mazhan in Tengchong Basin. Two low-velocity and resistive layers were recognized in the crust within the basin.
