New research reveals overflowing lakes on Mars may have traced the dramatic lanterns of the planet

A new study has shown that the canyons visible on Mars today could have been formed billions of years ago by the swelling of the lakes that burst out of their basins.

At present, the majority of Martian waters are steadily remote to its ice caps, but once this was in abundance on this planet, and now new research shows that overflowing lakes may have traced the dramatic gorges of the planet.

As Phys.org reports, billions of years ago, the water would once have passed through huge rivers on Mars that were emptied into craters that eventually became huge seas and lakes.

Now a new study conducted by the University of Texas at Austin has evidence that sometimes these crater lakes have become so full of water that swollen lakes have ended up overflowing from their basins that would have created flooding large enough to end up creating gorges of the planet. In fact, it is also believed that some of these floods on Mars would be so intense that canyons might have formed in just a few weeks.

Chief writer Tim Goudge, who is a post-doctoral research at the UT Jackson School of Geosciences, explained that his new research reveals that geological activities such as floods could have had a much greater impact than plate tectonics when it came to shaping the features now you see on Mars today.

"These coastal lakes are quite common and some of them are quite large, some as large as the Caspian Sea." We believe this style of catastrophic flood of overflow and rapid incision of exit canyons was probably quite significant on the surface of early Mars.

Scientists already know that many of Mars craters were once filled with water and turned into paleo salads. More than 200 of these paleochristian areas were located next to exit gorges, sometimes extending hundreds of kilometers apart, however, before this new study, scientists were unable to determine whether these canyons were formed quickly or for long periods, years.

Searching for photos from NASA's Mars Reconnaissance Orbiter, the researchers carefully analyzed the topography of 24 of their palettes, skulls and their stores and found evidence of flood events here. In fact, one of the veterans studied was the Yellow Crater, which is currently considered a possible landing position for Land Mars 2020.

As Goudge pointed out, "This tells us that things that are different between planets are not as important as the basic physics of the overflow process and the size of the basin. You can learn more about this process by comparing different planets as opposed to just thinking about what's happening on Earth or what's happening on Mars.

The new study, which describes how Mars's gorges could have been formed by overflowing lakes, was published in Geology.
