WEAKENING OF DUNITE BY SERPENTINE DEHYDRATION

A SHEAR PRESS HAS BEEN USED TO DETERMINE THE MECHANICAL BEHAVIOR OF SERPENTINIZED DUNITE AND FORSTERITE AT NORMAL PRESSURES TO 50 KILOBARS, TEMPERATURES TO 900 DEGREES C; AND STRAIN RATES FROM .10 TO .0001 PER SECOND. THE SHEAR STRENGTH OF DUNITE, CONTAINING LESS THAN 5 PERCENT BY VOLUME OF SERPENTINE, IS REDUCED BY AT LEAST 30 PERCENT AS THE TEMPERATURE IS RAISED FROM 300 DEGREES TO 520 DEGREES C. ABUNDANT KINK BANDS DEVELOP AT NORMAL PRESSURES ABOVE 35 KILOBARS AT 27 DEGREES C AND AT LOWER PRESSURES AS THE TEMPERATURE IS INCREASED. /AUTHOR/
