摘要
对采自中国内蒙古的一种长英质麻粒岩进行了高温高压变形实验。实验在氯化钠传压介质活塞圆筒式压缩装置上完成。实验条件为ｔ／℃：６７０～９００，ｐ／ＧＰａ：１．１，ε／ｓ：１０－４～１０－７。用光学显微镜及高压透射电镜对实验样品的显微构造进行了观察研究。
A felsic granulite from exposed lower crustal terrains in Neimenggu,North China,was deformed at confining pressure of 1.1 GPa,temperatures of 670℃￣900℃ and constant strain rates of 10 -4 ￣10 -7 /s.Deformation experiments were carried out in a Griggs Blacic solid medium apparatus with salt as the confining medium.The investigations to the microstructures of experimented samples were completed by the optical microscopy and transmission electron microscopy.The implications of the experimental results for the deformation properties of the continental lower crust were discussed.
