This special publication Perspectives in Carbonate Geology is a collection of papers most of which were presented at a symposium to honor the 80th birthday of Bob Ginsburg at the meeting of Geological Society of America in Salt Lake City in 2005. The majority of the papers in this publication are connected with the study of modern carbonate sediments. Bob Ginsburg pioneered the concept of comparative sedimentology - that is using the modern to compare to and relate to and understand the ancient. These studies are concerned with Bobs areas of passion: coral reefs and sea-level; submarine cementation and formation of beach rock; surface sediments on Great Bahama Bank and other platforms; origin of ooids; coastal sediments; formation of stromatolites; impact of storms on sediments; and the formation of dolomite. The remainder of the papers apply the study of modern environments and sedimentary processes to ancient sediments.   Recent other publications of the International Association of Sedimentologists   SPECIAL PUBLICATIONS 40           Analogue and Numerical Modelling of Sedimentary Systems From Understanding to Prediction Edited by P. de Boer, G.
