Comprehensive field tests were made to determine whether surface geophysical techniques could be used to detect and delineate faults in uranium deposits. The tests included seismic refraction, magnetometer, electrical resistivity, airborne infrared thermal scasmlug, and airborne photography. The method of horizontal resistlvit~ profiling with electrode spacings in the range of lO to 15 feet was most diagnostic of faults, and is quick, inexpensive end easily used.

PROC.EIGHTH INT.CONF.ON SOIL MECH.FOUND.~NGNG,MOSCOW, 1974,Vi. 2,1974, Ph87-494. The instrumemt described in this paper measures the lateral stress, the undrained stress-strain properties and the peak stress ratio of soft clays in drained conditlons. It consists of a long hollow cylinder of 39~mn diameter which can be drilled into the ground with minin~m disturbance. The cylinder comprises a special cutting head, load cells and a pressuremeter.
