Abstract
IN October 1952 work began on a deep boring at Cambridge under the joint sponsorship of the Geological Survey and the Geology Department of the University. Drilling operations ceased in March 1954 at a depth of 860 ft. 3 in., and the hole, lined with aluminium tubes to 588 ft., was left permanently open. The principal object of this undertaking was to gain further information on the underground geology of the Cambridge region, the Palæozoic succession being of particular interest1,2. To this end continuous coring was carried on below 176 ft. 6 in. A preliminary description of the borehole was published in 19533. An outline of the lithology is given at the head of Fig. 1.
