This image obtained by #NASA’s Mars Reconnaissance Orbiter #MRO probe at 272.2 km high, shows a crater in the Elysium Planitia region on #Mars. Its background and plan along with its irregular texture and possible presence of cooling fractures indicate that this was partially filled with lava. The north side of the image also shows more extensive lava deposits (top, left) surrounding the scattered material (expels blanket) by a larger impact crater (bottom right) when he graduated.
Apparently, the lava flowed into the minor crater through the visible canal above left.
However a more detailed 3 D analysis reveals that the smallest crater lies at the top of the blanket material from the larger crater, thus above lava deposits further north. Considering that lava does not flow from lower levels to higher (by amount), the explanation should be different. There is enough evidence of lava flows in this region that have fluid at levels above the current surface, after being drained again. It could have been what happened in this case La lava flooded the north plain south above the current surface, flooding the smallest crater until it filled it. Later the lava was drained. until it filled it. Later the lava was drained back north, forming the canal and drainage part of the lava that fulfilled the crater. 3 D topographic information was obtained with a stereographic projection of two images, which allowed to answer questions that would not be possible with a single image.
