摘要
In order to reveal the characteristics of diorite melt composition under different degree of melting, the authors performed the experiments to analyse the melt composition while the diorite was being melted under high pressure and high temperature. The authors came to the following conclusions. When the melting was in the first degree, the composition of the melt is that of basalt. As the melting degree increasing, the characteristics of the melt composition were being changed from basic to medium-acidic, from potassium-rich to sodium-rich, and from strong alkaline to alkaline and subalkaline.
