焦永玲等对笔者发表在《高校地质学报》2012年第18卷第1期的“含水大陆下地壳的部分熔融:大别山C型埃达克岩成因探讨”一文提出质疑。针对他们的问题,笔者进行了回复,并提出:(1)大别山C型埃达克岩的源岩可能是基性的(SiO2含量50%左右),但是比较准确的成分估计还需要进一步研究;(2)变质含水基性岩(角闪岩)在1.0~1.2 GPa压力下(相当于35~40 km)可以形成含石榴石20%以上的残余体;(3)中钾的角闪岩(K2O含量1%左右)部分熔融可以形成高钾钙碱性长英质熔体(K2O含量3.5%~5%)。%We reply here to the comments of Jiao et al. on our previous paper“Partial Melting of Hydrous Lower Continental Crust: Discussion on the Petrogenesis of C-Type Adakites From the Dabie Orogen”. We propose that (1) the protoliths of the C-type adakites from the Dabie orogen might have a basic composition with SiO2 content of ca. 50%, but more accurate estimation is to be investigated, (2) partial melting of amphibolite at 1.0~1.2 GPa ( corresponding to a depth of 35~40 km) can result in residues containing ≥20% garnet, and (3) medium-potassium amphibolitic protolith (ca. 1% K2O) can generate high-K calc-alkaline felsic melts with K2O content of 3.5%~5%.
