Geology Of Mars: Giant Flooding That Took Place 4 Billion Years Ago

Huge floods have washed away Gale Crater, located on The Martian equator, and this event, which occurred 4 billion years ago, also contains clues that it may have ended a possible life that was going on here. According to data collected by NASA’s Curiosity shuttle and subsequent analysis conducted jointly by Jackson State University, Cornell University, The Jet Propulsion Laboratory and the University of Hawaii, the deposits of mega-floods that occurred in Gale Crater in the youth of Mars had an impact on the climate.

According to an article published in Scientific Reports at the beginning of last month, the mega-flood caused by the motion of heat energy created by the meteor effect must have turned the ice on the surface of Mars into a flood. Mega floods have been discovered on Mars for the first time through detailed sedimentological data, which has recently been increasingly used in field geology studies. Astrobiologist Alberto G. According to Fairén, the sediments left behind by the floods had not been discovered before. Just as it applies to Earth, geological features have recorded the effects of water and air movements.

The giant flood event, which is the subject of research, can be observed in the Gale Crater sedimentary layers formed by giant waves. Megadalga Only (Ing. “megaripples”) are seen as elevations of 150 meters between them, reaching 10 meters in height. According to the researchers, the formations, which are seen as the result of giant waves spreading along the floor of Gale Crater 4 billion years ago and are indicative of a mega flood, look exactly like the shapes formed on the surface of the Earth 2 million years ago.

It was noted that the meteor effect, the cause of the giant flood, also caused a large release of carbon dioxide and methane. The effect of water vapor created by heat with this gas flow scattered from dull reserves must have created a warm and humid climate condition in a short time. Condensation, on the other hand, may have created clouds of water vapor and caused downpours along the planet’s surface.

This water again filled into Gale Crater, merging with the water coming down from Mount Sharp, creating ridges of a mixture of muck and gravel caused by giant and sudden floods, creating a structure that Rose and descended. The Curiosity shuttle research team points out that Gale Crater once had permanent lakes and streams, and that this large stable presence of water is enough to support microbial life. The young planet Merih was a geologically active and mobile planet. Mars, an area geology capable of containing ice and liquid water on its surface, was probably a habitable planet in its early days.
