Mr. Riedel et C. Janssen, A NEW SHEAR APPARATUS FOR EXPERIMENTAL DEFORMATION OF ROCKS UNDER THEMICROSCOPE, Journal of structural geology, 17(3), 1995, pp. 455-457
A new experimental technique for the study of deformation processes in
rocks in transmitted light under the microscope uses a modified sapph
ire anvil cell in which one of the sapphire anvils can be rotated and
thus permit the deformation of a thin solid sample disc. The deformati
on can be observed during the experiment through the anvils using a po
larizing microscope stage. The technique is applicable up to 450 degre
es C and up to 2 GPa confining pressure in the central part of the sam
ple.
