摘要: DURING the summers of 1961, 1962 and 1963 temperature gradient measurements were made in a hole drilled Brent Crater1, which is thought to be Cambrian age about three miles north Cedar Lake Algonquin Park, Ontario. This hole, was started on March 10, 1959, completed 3,489 ft. May 23, mainly passes through limestones shales for top 750 then complicated series rocks ranging from indurated tuffs porous breccias. By time first 1961 had become blocked at depth 1,285
