| Abstract: | This paper deals with some results of experimental study on semi-brittle behavior of rocks at the conditions relevant to the middle-lower crust. By observing and analysing macro-characteristics of deformed granite, gabbro and quartzite, such as creep curve, creep type, relationship between creep rate and time, creep deformation, steady-state creep rate and flow stress, as well as creep failure features, some basic regularities of semi -brittle rock creep are recognized. From the obtained data a semi-brittle creep mechanism map in flow stress-temperature and pressure space is suggested for predicting the potential semi-brittle creep behavior of rocks in the Earth's crust. |
