Tableland

A tableland is an area containing elevated landforms characterized by a distinct, flat, nearly level, or gently undulating surface.Depending on either their size, other physical characteristics, or geographic location, the landforms comprising a tableland are individually referred to by a number of names including either butte, mesa, plateau, potrero, tepui, or tuya.The tepui of South America are a type of sedimentary tableland composed of erosional outliers of flat-lying Precambrian quartz arenite sandstone that tower over the surrounding jungle underlain by crystalline basement rocks.[6][7] In addition, the eruption of either lava or pyroclastic flows can deposit a solid surface layer of volcanic rock that is relatively flat.As in case of the duricrusts, the resulting lava or pyroclastic flows are sufficiently tough to form the flat-lying caprock of tablelands when breached and incised by rivers and streams.
