Advances in Organic Geochemistry documents the proceedings of the First International Meeting of the European Branch of the Organic Geochemistry Group held in Milan on September 10-12, 1962. This compilation discusses research and review problems relating to the geochemistry of organic materials in the earth's crust, such as petroleum and coal, as well as less highly concentrated, but more widespread, organic matter present in various rocks, soils, and waters. Other topics covered include duplex origins of petroleum; chemical study of coal macerals; mineralized micro-structures in carbonaceous meteorites; primary investigation of the oleiferous dolerite of Dyvika; and organic residues in Jurassic oolitic limestones. Geochemical aspects of the microbial modification of carbon compounds; trace metal analysis of oils and asphalts by neutron activation techniques; and application of ultraviolet spectroscopy to the examination of dissolved organic substances in water are also deliberated in this text. This publication is beneficial to students and individuals conducting work on organic geochemistry.
