Dynamic properties of stick-slip friction of rock. 14F, ITR. J.GEOPHYS. RES. ,V81,N5,1976, P881- 888. Rupture and particle velocities were measured for stickslip events occurring during frictional sliding on surfaces composed of Westerly granite and Twin Sistere dunite and on a combination of the two rocks.

Tectonic processes 494 30BBOLD, PR UNIV. LEEDS, GB KNOWLES, RA UNIV. LEEDS, GB Automsted apparatus for model deformation. 2F, IR. TECTONOPHYSICS,V31,N1- 2,1976, PT~9-T53. An increasing interest in the use of scale mod_ols to simulate tectonic processes has led to the design and cou~ structiou of several kinds of apparatus for model defor. cation. According to the boundary conditions required, a model may be deformed in one of sezeral rigs of different design. All the rigs are powered by one drive system which may be controlled manually or automatically to provid~ the desired stresses or strain rates in the model. Auth.
