A possible plate tectonic explanation for the northern lowlands. The Boreal plate is shown in yellow. Trenches are shown by toothed lines, ridges by double lines, and transform faults by single lines, modified from Sleep, 1994. [11] Endogenic hypotheses include the possibility of a very early plate tectonic phase on Mars. [11]
A marsquake is a quake which, much like an earthquake, is a shaking of the surface or interior of the planet Mars. Such quakes may occur with a shift in the planet's interior, such as the result of plate tectonics, from which most quakes on Earth originate, or possibly from hotspots such as Olympus Mons or the Tharsis Montes.
Along the Motagua Fault trace (1976 Guatemala earthquake) where it crosses the Gualán soccer field. This zigzag type of fault trace is known as "mole track", which is best developed in hard-packed, brittle surface materials. The San Andreas fault trace runs along the base of the Temblor Range of mountains near Bakersfield, California. (The ...
Alba's tectonic features are almost entirely extensional, [52] consisting of normal faults, graben and tension cracks. The most common extensional features on Alba Mons (and Mars in general) are simple graben. Graben are long, narrow troughs bound by two inward-facing normal faults that enclose a downfaulted block of crust (pictured right).
Generalised geological map of Mars [1] Mars as seen by the Hubble Space Telescope. The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology.
China's Zhurong Mars rover found strange geometric shapes below the surface, sparking curiosity and raising questions about the planet's ancient environment. A Mars Rover Discovered Bizarre ...
It is believed that plate tectonic processes could have been active on Mars early in the planet's history. [28] Large-scale redistribution of lithospheric crustal material is known to be caused by plate tectonic processes on Earth.
Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. [8] A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars. [9] Layers can be hardened by the action of groundwater.
