This symposium on “The Determination of Diagenetic Paleotemperatures” was originally sponsored by the Eastern Section of the Society of Economic Paleontologists and Mineralogists. All but one of the papers published here were presented orally at the 11th Annual Northeastern Section, Geological Society of America meeting on March 27, 1976. The original concept of the symposium was to bring together people using a wide variety of geochemical and mineralogical techniques and to discuss the application of such techniques to a common geological problem. Although a number of these tools are used routinely within the petroleum industry, they are not necessarily generally applied throughout the geological profession. Thus, the symposium served the function of familiarizing a broad range of geologists with a significant part of the spectrum of techniques available for the quantitative or semi-quantitative determination of burial temperatures of sediments. The reader should be aware, however, that many other techniques, not discussed here, are also available for such studies. All the techniques presented have some degree of uncertainty in their determinations and may be affected by one or more factors such as water chemistry, pressure, organic carbon or hydrocarbon concentration, or geologic time. Therefore, it is often advisable to use two or more complementary techniques which provide a cross-check. The papers in this volume, written mostly as review articles rather than descriptions of new applications, provide the reader with the background needed to select and apply the technique most useful for a given problem.papers in this volume fall into two natural

There are a number of gaping holes in accumulated knowledge within the discipline of sedimentology. Perhaps one of the largest holes has been the general subject of diagenesis in clastic rocks. It was therefore fortuitous that two symposia covering various aspects of diagenesis (mainly in clastics) were presented a year apart in different parts of the country but with the same motivation – to contribute to the closing of that knowledge gap. Sedimentologists now have a fairly good idea of the what and the how of sediment deposition. What happens after the sediments are lithified has frequently been ignored. It was the aim of both editors of this publication to approach the subject from two different viewpoints. Schluger directed a symposium which looked mainly at clastic reservoirs, and Scholle presented a symposium which examined various aspects of paleotemperature control of diagenesis.
