Percy Evans completed his MA in Geology in 1938 from the University of Cambridge. He was the Chief Geologist of the Burmah Oil Company Ltd, London and served on the governing body of the Indian School of Mines, Dhanbad.
Academic and Research Achievements: Evans did extensive work on the geology of Burma, Assam and Punjab for more than 50 years. He made major contributions to the knowledge of geology of Assam, initially by field mapping, later by integration of the geological and geophysical results. He was ahead of his time in the application of geophysical prospecting, exploration of heavy minerals, micropalaeontology and drilling technology. He introduced electrical well-bore logging, gravity survey, seismic survey, electrical resistivity survey and tellurie current survey in Assam. He invented a well inclinometer and discovered Sui gas field (in 1952) and Nahorkatiya oilfield. He was one of the first geologists in India to recognize the existence in many mountain valleys of the phenomenon of ‘Valley bulge’. Towards the end of his career, Evans studied the Pleistocene ice-age cycles and glaciations.
Awards and Honours: Percy Evans was awarded a Gold Medal from the Mining, Geological and Metallurgical Institute of India (1932) and the Murchison Medal from the Geological Society of London (1947). He was a Fellow of the Royal Geographical Society, the Geological Society of London and Indian Association of Petroleum Geologists. He was the President of the Geology Section of the Indian Science Congress in 1932. He was a Member of the Asiatic Society, Royal Society of Arts (London), Royal Institution of Great Britain, London Natural History Society, and Geological Society of India and an Honorary Fellow of the Mining of the Geological and Metallurgical Institute of India (1964).
