Ephemeral streams, dry washes, gullies, draws and arroyos are common names for a major element of Western landscapes. By definition ephemeral streams are characterized by short periods of flow, following local and intense rainfall, and alternating with long periods in which the channel is dry (Fig.] ,2).

The great contributions of CAYEUX (1941) have been a major factor in recognizing the environments in which sediments were deposited. However, I can certainly agree with BROUWER (1962) that Cayeux was too pessimistic in saying that it is uniquely by the analysis of ancient sediments that we can get to understand the conditions in marine basins of the past. It is quite possible that some of these ancient deposits were formed under conditions that no longer exist, but it seems likely that our failure to find analogies between past and present is due largely to the sparcity of studies in modern sedimentary basins. Compared to the thousands of geologists who are investigating ancient sediments there are only a handful of us who have been studying the Recent although we now have many new recruits. <...>

The Mediterranean Sea lies between Europe, Asia and Africa in an area famous for its ancient civilizations and cultural developments. It was an area where marine navigation was developed and where many trade routes intersected. The publication of one of the first monographs on marine geology and geography by Marsilli in 1725 suggests that the Mediterranean Sea was the cradle of marine geology.

The formation and transformation of oceanic sediments involve geological, biological, physical and chemical processes. The knowledge of oceanic sediments and other objects of the Earth and Ocean Sciences therefore requires a multidisciplinary approach. This knowledge considerably increased during the past 50 years, closely following significant progress in the methods of investigation at sea and in the laboratory. In addition, ocean exploration is deeply rooted in History. Our understanding of the Ocean (including oceanic sediments and related processes) progressed step-by-step, following the evolution of techniques and ideas. Chapters 1 and 2 summarize the historical aspects of Oceanography (focusing on Marine Geology), along with the variety of processes that drive the formation and transport of sediment particles as well as their accumulation and transformation in oceanic sediments. <...>

В книге обосновывается самостоятельность нового направления в науке — биоседиментологии. Она находится на стыке двух дисциплин — палеонтологии и седиментологии. Цель этого направления — исследовать роль организмов в осадочном процессе. Приводится характеристика биоседиментологии во всех аспектах взаимосвязи с другими дисциплинами. Развиваются лучшие современные классификации зарубежных ученых для биогенных структур, пород и организмов. При этом используются самые последние разработки отечественных ученых в этой области. Предложена классификация первичных карбонатных пород, рассмотрена роль организмов в осадочных процессах на Земле в течение всей ее геологической истории

Sedimentology and stratigraphy are neighbors yet distinctly separate entities within the earth sciences. Put in a nutshell, sedimentology searches for the common traits of sedimentary rocks regardless of age as it reconstructs environments and processes of deposition and erosion from the sediment record. Stratigraphy, by contrast, concentrates on changes with time, on measuring time and correlating coeval events. Sequence stratigraphy straddles the boundary between the two fields. It is a sedimentologic concept as it uses depositional anatomy to reconstruct environments and lateral facies change, and it is part of stratigraphy as it studies the vertical succession of sedimentary rocks and their succession and correlation. <...>

Besides pioneer works of the 60s, the tidal sedimentologist community really emerged in the 70s (see Klein, 1998). The first international conference on tidal sedimentology took place in 1973 in Florida (USA). It was devoted to carbonate facies, less to siliciclastic deposits and mostly to intertidal areas. The conference resulted in a book gathering case studies (Ginsburg, 1975). The fining‐upward tidal flat sequence represented at this time the tidal facies model; and this was mainly applied to carbonates. The growing knowledge in siliciclastic tide‐dominated environments was synthesized a few years later by Klein (1977). Following the paper of Visser (1980) demonstrating the record of tidal cycles in estuarine dunes, clastic tidal sedimentology evolved quickly towards more comprehensive and quantitative studies, both ancient and modern. A community was born <...>

This book is designed for a one-semester course in sedimentology taken by advanced undergraduate or graduate students. It gives detailed descriptions of sedimentary features and the analytical methods used to evaluate them and is intended to support and reinforce principles presented in lectures. Discussion of principles and processes is found in complimentary texts, such as Leeder's (1982) Sedimentology: process and product and selected readings in professional journals.
