摘要
To study the relationships of differential stresses and temperature to the melting degree of rocks, the authors use hornblende granulite to do some high-T and high-P experiments. Firstly, the authors carried out the dynamic melting experiment by imposing differential stresses from 0 to 25 MPa with step at 5 MPa on natural bulk rock samples under confining p and T at 100 MPa and 700 ℃, respectively. Then, the authors did the static experiment under the same confining pressure but without differential stresses by increasing the T from 700 to 900 ℃ with the step at 50 ℃. The experimental results indicate that the melting degree of rocks increases with the increase of differential stresses.
