Oxygen-isotope and trace element constraints on the origins of silica-rich melts in the subarc mantle [PDF]
Peridotitic xenoliths in basaltic andesites from Batan island in the Luzon arc contain silica-rich (broadly dacitic) hydrous melt inclusions that were likely trapped when these rocks were within the upper mantle wedge underlying the arc.

The Significance of Multiple Saturation Points in the Context of Polybaric Near-fractional Melting [PDF]
Experimental petrologists have successfully located basaltic liquid compositions parental to mid-ocean ridge basalt that are, within experimental resolution, multiply saturated with three-phase harzburgite or four-phase lherzolite assemblages on their ...

Widespread abiotic methane in chromitites [PDF]
Recurring discoveries of abiotic methane in gas seeps and springs in ophiolites and peridotite massifs worldwide raised the question of where, in which rocks, methane was generated.
