  2. Dome (geology) - Wikipedia

    en.wikipedia.org/wiki/Dome_(geology)

    A dome is a feature in structural geology where a circular part of the Earth's surface has been pushed upward, tilting the pre-existing layers of earth away from the center. In technical terms, it consists of symmetrical anticlines that intersect each other at their respective apices .

  3. Structural basin - Wikipedia

    en.wikipedia.org/wiki/Structural_basin

    A structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat-lying strata into a syncline fold. They are geological depressions , the inverse of domes .

  4. Salt dome - Wikipedia

    en.wikipedia.org/wiki/Salt_dome

    Stratigraphically, salt basins developed periodically from the Proterozoic to the Neogene. The formation of a salt dome begins with the deposition of salt in a restricted basin. In these basins, the outflow of water exceeds inflow. Specifically, the basin loses water through evaporation, resulting

  5. Salt surface structures - Wikipedia

    en.wikipedia.org/wiki/Salt_surface_structures

    Cratonic basins – Within continental boundaries, salt deposition can occur anywhere that bodies of water can collect. Even away from ocean sources, water is capable of dissolving and carrying ions that can later precipitate as salts, and when the water evaporates, the salts are left behind.

    Map showing worldwide drainage basins and triple divides. A triple divide or triple watershed is a point on Earth's surface where three drainage basins meet. A triple divide results from the intersection of two drainage divides.

    Middle Devonian paleogeography. The Cincinnati Arch is a broad structural uplift between the Illinois Basin to the west, the Michigan Basin to the northwest, and the Appalachian Basin and Black Warrior Basin to the east and southeast.

  9. Geology of North America - Wikipedia

    en.wikipedia.org/wiki/Geology_of_North_America

    The Basin and Range Province is a series of linear block fault mountains with adjacent sediment-filled downfaulted valleys, having been caused by crustal extension around 17 million years ago. The valley floors are made up of thick sediment deposits which have eroded off the mountains and filled the valleys, so that the region is a regular ...
