ANTECLISE (from Greek words "anti" (opposite) and "klisis" (inclination) * EN: anteclise; DE: Anteklise; FR: anteclise; ES: anteclisa; RU: антеклиза) is the extensive vault-shaped slightly inclined uplift of the layers of the Earth's crust within the limits of the platforms (plates), which is the opposite of the syneclise.

Anteclises have mostly oval or round outlines; their sizes reach hundreds of kilometres across. The dip of the layers on the limbs is measured with the fractions of the angular degree. The anteclises develop themselves during the long time, during several geological periods. Consequently to this, the thicknesses of sedimentary strata within the vaulted parts of anteclises are decreased, often there are missing the whole series, which are developed within the adjacent syneclises. The basement of the platform is embedded here at the shallow depth, and sometimes even appears on the surface. The examples of anteclises are: on the Russian plate, the Voronezh one, Belarus one; on the Siberian platform, the Anabar one.
