“…This structure was also imaged by a refraction/wide-angle reflection profile [Zhao et al, 2006 . Our own previous MT profiles along the Altyn Tagh Fault from near Aksay toward its eastern termination [Xiao et al, 2011[Xiao et al, , 2012[Xiao et al, , 2013[Xiao et al, , 2015 showed that the depth of the vertical resistivity contrast related to the ATF decreases eastward and terminates against mainly dip-slip faults at the northern margin of the Hexi Corridor.
