Precambrian stromatolites have received in depth, consideration from geologists and paleontologists; they were indeed searching for biosedimentary structures that were sufficiently characteristic and widely distributed to be considered as useful tools for stratigraphic correlation. Silicified stromatolites are also of interest as they contain preserved traces of ancient life. Calcareous Phanerozoic stromatolites have not received very much attention from geologists. Logan's too schematic morphological classification of 1964, was not so helpful to the knowledge of Phanerozoic stromatolites because neither their morphology nor their microstructure were studied in the same detail in which Proterozoic stromatolites have now been described. We therefore know little about the Phanerozoic stromatolites which, do, however, show an interesting range of diversification. A major questions stiII remaining to be answered include the history of stromatolite development and wether their morphology has "evolved" in addition to detailed information concerning Cenozoic nonmarine stromatolites which precipitate carbonate and the Recent giant stromatolites which trap particles. For these reasons Claude Monty, in 1981, launched the first volume of what was going to be a series on "Phanerozoic stromatolites" in order to describe their morphology, microstructure and paleoecology and to present them in their stratigraphic context.

Developments in Geotectonics, 7: East African Rifts focuses on the movements, structure, and behavior of the East African rift system. The selection first offers information on the surface structure and plate tectonics of Afar; tectonic and magmatic significance of volcanism in the Afar depression; and preliminary interpretation of the gravity field of Afar, northeast Ethiopia. Discussions focus on crustal models of Afar based on gravity and seismic data, tectonics, volcanism, geological setting, and crustal extension. The text also elaborates on the gravity survey of the central part of the Ethiopian Rift Valley and an aeromagnetic survey of the Afar triangle of Ethiopia. The book examines the arrangement and development of continental rift zones, East African rift development, and the seismicity of the East African rift system. Topics include earthquake mechanisms, seismicity, and the main categories of rift zones. The manuscript is a dependable reference for readers interested in the East African rifts.

This new volume on the Geology of East Africa provides a concise account of the multi-faceted regional geology and stratigraphy of East Africa, that is Kenya, Tanzania and Uganda. Much of the data presented, however, is highly relevant to the surrounding countries and regions as well. Professionals and students, intending to delve into the details of the geological history of that region will appreciate the present volume as a stepping-stone, paving the way to additional studies of the numerous references given in this work.
