Beta Regio

Beta Regio

A highland area on Venus, somewhat smaller than Aphrodite Terra and Ishtar Terra. Located in the planet's northern hemisphere at Venusian coordinates 25.3° N latitude, 282.8° W longitude, it has a large rift valley and two large shield volcanoes, Rhea Mons and Theia Mons. Satellite tracking shows that there is a gravity anomaly over Beta Regio.

A basic tenet of this model is that tectonism and magmatism [the formation of molten material] at Beta Regio and western Aphrodite are dominated by the evolution of plume heads or blobs as they rise to the base of the lithosphere and spread laterally," the authors write in the November GEOPHYSICAL RESEARCH LETTERS.
