A raised beach, coastal terrace, or perched coastline is a relatively flat, horizontal or gently inclined surface of marine origin, mostly an old abrasion platform which has been lifted out of the sphere of wave activity (sometimes called "tread"). Thus, it lies above or under the current sea level, depending on the time of its … Visa mer The platform of a marine terrace usually has a gradient between 1°–5° depending on the former tidal range with, commonly, a linear to concave profile. The width is quite variable, reaching up to 1,000 metres (3,300 ft), and seems … Visa mer For exact interpretations of the morphology, extensive datings, surveying and mapping of marine terraces is applied. This includes stereoscopic aerial photographic interpretation Visa mer Marine terraces play an important role in the research on tectonics and earthquakes. They may show patterns and rates of tectonic uplift and thus may be used to estimate the tectonic activity in a certain region. In some cases the exposed secondary landforms … Visa mer Uplift can also be registered through tidal notch sequences. Notches are often portrayed as lying at sea level; however notch types actually form a continuum from wave notches … Visa mer It is now widely thought that marine terraces are formed during the separated highstands of interglacial stages correlated to marine isotope stages (MIS). Causes The formation of marine terraces is controlled by … Visa mer Different methods for dating and correlation of marine terraces can be used and combined. Correlational dating The … Visa mer Raised beaches are found in a wide variety of coast and geodynamical background such as subduction on the Pacific coasts of South and North America, passive margin of the Visa mer Webbformation immediately preceding the formation of the beach in southern Ireland. The beach cannot therefore be assigned with any confidence to the same stage as the raised …
