WebApr 15, 2024 · Connor and Kurokawa et al. showed that the margins of the MGVF are characterized by normal faulting (horst-and-graben structures), revealing an overall extensional stress-regime. In this regime, the maximum compressive stress σ 1 is vertical, the maximum horizontal compressive stress σ 2 is oriented in a NE-SW direction, and the … WebHorst and Graben Structure In areas that are characterized by extensional tectonics, and with many normal faults arranged side-by-side, some blocks may subside (settle downward) relative to neighbouring parts. This is typical in areas of continental rifting, such as the Great Rift Valley of East Africa or in parts of Iceland.

A graben is a valley with a distinct escarpment on each side caused by the displacement of a block of land downward. Graben often occur side by side with horsts. Horst and graben structures indicate tensional forces and crustal stretching. Graben are produced from parallel normal faults, where the displacement of the hanging wall is downward, while that of the footwall is upward. The faults typically dip toward the center of the gr… WebApr 10, 1990 · Four different mechanisms (frictional heating, magmatic intrusion, free convection, and forced convection) have been tested as possible causes to explain the localized and relatively high geothermal anomalies found along master faults of graben structures.
