GSA Today: Terrestrial analogy to ancient martian ocean?
February 2014 GSA Today now online
Boulder, Colorado, USA – In the February issue of GSA Today, Lorena Moscardelli of the University of Texas at Austin Jackson School of Geosciences documents evidence in support for the existence of a martian ocean during the late Hesperian–early Amazonian by showcasing a new terrestrial, deep-water analogy.
Although the existence of an ancient martian ocean based on alleged paleoshorelines has been heavily contested, Moscardelli describes boulder-size rocks on the northern plains of Mars that are similar to boulder- and kilometer-scale blocks transported to many terrestrial deep-water environments by subaqueous mass-transport events. According to Moscardelli, the comparison supports the existence of an ocean on Mars and a catastrophic mass-transport origin for the boulders not unlike events documented along continental margins on Earth.
