... In this study we try to answer the question about the possible primary melt for Guli massif, comparing the composition of spinel-group minerals from the dunites of Guli massif with model compositions of spinel-group minerals, which are in equilibrium in system, chemically corresponding with primary melt. We consider three candidates to be a primary melt for Guli massif: meimechite, picrite and khatangite. ... The influence of this factor is strongly limited by the H 2 O solubility in the melt. ...
