Dear Craig,
A study by Jahn et al., (1999) comes to mind. They look at UHP rocks from
Central China and specifically at partial melting of metasomatised mantle
which produces basic magmas (crust-mantle interaction).
Jahn, B.-M., Wu, F., Lo, C.-H. and Tsai, C.-H. (1999).
Crust-mantle interaction induced by deep subduction of the continental
crust: geochemical and Sr-Nd isotopic evidence from post-collisional
mafic-ultramafic intrusions of the Northern Dabie complex, central China.
Chemical Geology 157 (1 - 2) p. 119 - 146.
Hope it's useful.
Cheers
Riana

Subject: high-pressure melt textures
Hi all,
Does anyone know of any references to textural relationships of
high-pressure (eclogite mainly, but HP granulite also) melt? I'm
particularly interested in cases where people have displayed melt
infiltrating from acid layers into basic layers during high-pressure
metamorphism and crystallising a high-pressure assemblage from melt (in
equilibrium with HP assemblage of "host"). I would be even more
interested if anyone has worked on partial melt in basic rocks formed
during high-pressure metamorphism.
The examples I have may have undergone ductile shearing during partial
melt formation or infiltration via a melt/reaction weakening process.
Thanks in advance for any help or suggestions.
Regards,
Craig Storey
