Brain terrain
Brain terrain is a feature of the Martian surface, consisting of complex ridges found on lobate debris aprons , lineated valley fill and concentric crater fill . It is so named because it suggests the ridges on the surface of the human brain. Wide ridges are called closed-cell brain terrain, and the less common narrow ridges are called open-cell brain terrain. [1] It is thought that the wide closed-cell terrain contains a core of ice, and when the ice disappears the center of the wide ridge collapses to produce the narrow ridges of the open-cell brain terrain. Shadow measurements from HiRISE indicate the ridges are 4-5 meters high. [1] Brain terrain has been observed to form from what has been called an " Upper Plains Unit ." The process begins with the formation of stress cracks. The upper plains unit fell from the sky as snow and as ice coated dust. [2]

With the superior resolution of cameras on Mars Global Surveyor (MGS) and MRO, we have found the surface of lobate debris aprons, lineated valley fill, and concentric fill have a complex tangle of ridges that resemble the surface of the human brain . Wide ridges are called closed-cell brain terrain , and the less common narrow ridges are called open-cell brain terrain. [1] It is thought that the wide closed-cell terrain still contains a core of ice, that when it eventually disappears the center of the wide ridge collapses to produce the narrow ridges of the open-cell brain terrain. Today it is widely accepted that glacier-like forms, lobate debris aprons, lineated valley fill, and concentric fill are all related in that they have the same surface texture. Glacier-like forms in valleys and cirque-like alcoves may coalesce with others to produce lobate debris aprons. When opposing lobate debris aprons converge, linear valley fill results [2] They probably all contain ice-rich material. |
