Thus far, our understanding of the emplacement of Xuebaoding granite and the occurrence and evolution of the Songpan-Garze Orogenic Belt has been complicated by differing age spectra results. Therefore, in this study,...
In order to provide the age for the ISEA (one reversed event in the CNS) a combined rock magnetic, pa-leomagnetic and geochronologic study has been conducted on two Cretaceous andesitic basalt lava flows from Sanbaoyi...
