This book is a proceedings volume from a 1985 symposium sponsored by the Geological Society of London and the International Geological Correlation Program Project No. 219 (Comparative lacustrine sedimentology in space and time). That meeting set the tone for subsequent IGCP No. 219 symposia, where sedimentary, petroleum, and structural geologists, as well as geochemists and paleontologists, have grappled with important problems in lake geology. The 1985 meeting on lacustrine source rocks considered the following questions: (1) How can we develop more refined methods for interpreting depositional environments from lake deposits and fossils , (2) What limnologic, sedimentologic, and tectonic conditions are most conducive to the production and accumulation of organic matter in lakes , (3) What diagenetic changes affect organic-rich sediments after deposition , and (4) How can questions 2 and 3 be best evaluated from the stratigraphic record As a group, lakes are extremely productive ecosystems. Marine environments that would be ranked as high productivity systems are only moderately productive by lacustrine standards. Even with energy transfer rates of less than a few percent from the primary producers to the sediment, lacustrine mudrocks can be extremely rich in organic matter. The major limitations of lacustrine source rocks are not lithologic but limitations of scale (both spatial and temporal). How, in the middle of a continent, do you get a hole in the ground that is both big enough and long-lasting enough to generate significant quantities of hydrocarbons
