【摘要】 <正>Natural fine-grained gabbro were deformed at 300MPa confining pressure in a paterson-type deformation apparatus in GFZ. Creep tests were performed at temperatures ranging from 800-1150 ℃, stresses from 4-500 MPa, and strain rates between 5*10-4-1*10-8s-1. The fine-grained gabbro is composed of -60 vol% plagioclase (most of grains Ab50-40An50-60更多还原
