摘要: 本文着重介绍了在中下地壳温度、压力条件下进行的几种岩石半脆性蠕变的实验研究结果。通过对这些岩石的蠕变曲线、蠕变类型、蠕变速度和时间、蠕变应变的关系、稳态蠕变速度-流动应力和蠕变破坏特征的观测、分析,阐述了地壳岩石半脆性蠕变的基本规律,并在温度、围压-流动应力座标系中给出了岩石半脆性蠕变的分区。

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.

Key words: Crustal rocks, Creep, Semi-brittle behavior, High temperature and high pressure
