Captured
wrinkle ridges, some faults that cross and surrounded by an elliptical crater ejects
butterfly-shaped, with the appearance of being liquid.
The
Mars Express space probe has discovered a wide range of tectonic features and
their impact in a volcanic region of Mars reveals that the planet has "a
complex geological history."
The
probe photographed last April Melas Dorsa, a volcanic region south of Valles
Marineris canyon located between the regions and Thaumasia Sinai Plana,
reported the European Space Agency (ESA) in a statement.
The
image captured wrinkle ridges, some faults that cross and surrounded by an
elliptical crater ejects as a butterfly appearance of being liquid.
According
to experts, the elliptical craters formed when asteroids or comets hit the
planet's surface at a shallow angle.
In
addition, the scientists explained that ejects surrounding the crater of Melas
Dorsa indicates the presence of subsurface ice that melted during the impact.
The
image also captured the edge of another large crater that seems to have been
buried for the most part during a distant era of volcanic dust and ash, which
contains concentric deposits, could provide clues to the composition of this
material.
The
crater is surrounded by several wrinkles that formed when horizontal
compression forces the crust pushed upwards.
The
image taken by Mars Express demonstrates that Melas Dorsa region originated
from different tectonic phases.
