英文摘要: 5GPa high-P/T deformation apparatus represents the overall best performance high P/T deformation apparatus for the lithosphere pressures. Such apparatus has never been built in our country. This project is aimed to develop a sophisticate 5 GPa modified Griggs-type deformation apparatus with better resolutions in pressure, temperature, stress and strain rate for study of processes in the Earth’s deep interior and international competition in studying geological sciences. The performance targets of the prototype include a maximum loading pressure of 5 GPa, a maximum temperature of 1600 centidegree, and a range of deformation strain rate of 0.01-0.0000001/s. The development of this new apparatus will promote our technique, method and equipment in high pressure and temperature rheology to international levels, and facilitate the development of rock rheology field.
