AbstractThis study reviews the morphology, hydrodynamics and sedimentology of 33 modern straits, including examples from diverse tectonic and climatic settings. Strait morphology ranges from short, simple straits to long, tortuous passages many 100s of kilometers long; depths range from 10 m to >1 km. The morphological building block of strait sedimentation is a constriction flanked by open basins; a single strait can contain one or several of these. Currents accelerate through the constrictions and decelerate in the basins, leading to a spatial alternation of high- and low-energy conditions. Currents in a strait can be classified as either ‘persistent’ (oceanic currents or density-driven circulation) or ‘intermittent’ (tidally or meteorologically generated currents). Constrictions tend to be bedload partings, with the development of transport paths that diverge outward. Deposition occurs where the flow decelerates, generating paired subaqueous ‘constriction-related deltas’ that can be of unequal size. Cross-bedding predominates in high-energy settings; muddy sediment waves and contourite drifts are present in some straits. In shallow straits that were exposed during the sea-level lowstand, strait deposits typically occur near or at the maximum flooding surface, and can overlie estuarine and fluvial deposits. The most energetic deposits need not occur at the time of maximum inundation.Supplementary material at https://doi.org/10.6084/m9.figshare.c.5746061

Contourite Drifts

The middle Ordovician of Pingliang area on the west margin of North-China platform is represented by a succession of deep-water sediments in which contourites are well-developed. Contour current deposits are well-developed. The contourites can be classified into:calcarenitic contourite, calcisiltitic contourite and calcilutitic contourite. Three typical contourite successions are recognized: complete contourite succession, incomplete contourite succession and contourite successions consisting only of calcarenitic contourites. According to the palaeocorrent and the palaeogeographic format analyse,carbonate contourite drift in the study area is unfolded crossing northwest-southeast, forwarding from southeast to northwest along the slope, and compared with other contourite drifts, it has some characteristics of coarser-grained sediment, thicker individual layers, and highly developed calcarenitic contourites and so on.

Archaeology of Domestic Landscapes of the Enslaved in the Caribbean examines the diversity of living environments that the enslaved inhabitants of the colonial Caribbean by analyzing archaeological evidence collected from a wide variety of sites across the region. Archaeological investigations of domestic architecture and artifacts illuminate the nature of household organization; fundamental changes in settlement patterns; and the manner in which power was invariably linked with the material arrangements of space among the enslaved living and working in a variety of contexts throughout the region, including plantations, fortifications, and urban centers. While research in the region has provided a considerable amount of data at the household-level, much of this work is biased towards artifact analysis, resulting in unfamiliarity with the considerations that went into constructing and inhabiting households. The chapters in this book provide detailed reconstructions of the built environments associated with slavery and account for the cultural behaviors and social arrangements that shaped these spaces. It brings together case studies of Caribbean slave settlements through historical archaeology as a means of exposing the diversity of people and practices in these various landscapes, across the British, French, Dutch, and Danish colonies in both the Greater and Lesser Antilles as well as the Bahamian archipelago.
