This book is a collected series of papers on the sedimentary geology of carbonate sediments deposited on shelves and offshore banks in cool to cold oceans. Contributions come mainly from a workshop organized by Jonathan Clarke held in Geelong, Victoria from January 14 to 19, 1995. Most earth scientists have traditionally viewed carbonate sediments as warm-water deposits and interpreted them as such in most of the geological record. Yet large areas of the modern seafloor are covered with neritic carbonate sediments formed in seawater that is colder than 20ºC. Such environments are not easily studied. Thus, our knowledge of cool-water carbonates has lagged far behind our understanding of their warm-water counterparts. This situation has changed somewhat as more and more investigators have braved the chill waters and rough seas. This book brings together a group of studies that illustrate the present status of our understanding and current research in a field that is in mid-life.

Three different types of cool-water carbonate platforms have been recognized in the Artinskian-Kazanian succession in North Greenland, Svalbard and the Barents Sea. The early Artinskian platforms are composed of limestones with a bryoderm-extended fauna dominated by bryozoans and crinoids, and include thick, submarine cemented bryozoan-Tubiphytes buildups. The late Artinskian to early Kungurian platforms are locally more than 40 km wide and have relatively steep slopes. They are dominated by brachiopods and bryozoans in high-energy inner shelf areas and trepostome bryozoans in more protected outer shelf areas. The late Kungurian to Kazanian platforms have a ramp like profile with a...
