An oasis in the ancient delta of the Tedjen River in southeast Turkmenia, first settled in the early Chalcolithic period, designated Anau I or Namazga I. The earliest sequence of 10 levels span the later 5th and 4th millennia BC. Typical settlements were small villages of mud-brick houses, though the central settlement of Geoksyur itself seems to have been much larger. The exploitation of this oasis indicates the existence of a developed agricultural economy involving the cultivation of both wheat and barley with the help of irrigation. The area gives its name to a style of painted pottery of the Namazga III period (late 4th millennium BC), with densely packed, repeated geometrics.
