Constant Strain-Rate Deformation of Amphibole Minerals.
Abstract
The amphibole minerals, hornblende and tremolite in single-crystal and polycrystalline form, were deformed in compression at confining pressures from 5 to 20 kb and temperatures from 27 to 1200C at a strain rate of 10 to the minus 5th power/sec. Twinning on ((-1),0,1) is the major ductile deformation mechanism below 800C at all confining pressures. Although among the strongest silicates thus far measured, amphiboles show two major weakening mechanisms at elevated temperatures and confining pressures. (Author)
