Abstract
THE Second Circular for the eighteenth session of the International Geological Congress, London, 1940, has now been issued. The sessional meetings will be held during July 31–August 8, 1940, and the following ten subjects have been listed for discussion: (1) metasomatie processes in metamorphism; (2) rhythm in sedimentation; (3) the geology of iron-ore deposits; (4) the geology of petroleum; (5) the geology of sea and ocean floors; (6) the pliocene-pleistocene boundary; (7) faunal and floral facies and zonal correlation; (8) earth movements and organic evolution; (9) the geological results of applied geophysics; (10) the geology and paragenesis of the ores of lead and zinc. One of these, the geology and paragenesis of the ores of lead and zinc, will form the subject of a symposium to which recognized authorities have been asked to contribute. It is intended to issue these accounts before the Congress and to promote discussion on them at the sectional meetings.
