“…Petrologic, mineralogical, and geochemical aspects of these UHP rocks have been thoroughly investigated during the past two decades (e.g., Liou et al, 1998;Xu et al, 2009). However, seismic properties of the UHP rocks have received relatively little attention, although such studies can provide basic constraints on the interpretation of seismic data from the modern and ancient convergent orogenic belts (Kern et al, 1999(Kern et al, , 2002Ji et al, 2003Ji et al, , 2007Wang et al, 2005aWang et al, , 2005bWang and Ji, 2009).…”
