With the perspective of slab melting, is this possible that slab melts and high MgO adakites form in this condition.
Respected Sir,
Please go through following reference. I hope it may be helpful to you.

Dear Sir
Yes, there are many papers about it. Normaly, the origin of High-Mgo adakites is partial melting of metasomatized mantle source above of young subduction zones.
There is a version that adakite felsic rocks are formed by of a mantle wedge melting (Macpherson et al., 2006).
