In another thread the fact Mars meteorites found on earth were of volcanic origin was emphasized. For this to occur a volcanic eruption capable of ejecting material from the Marian surface at escape plus velocities would have been very energetic. The beginning of the eruption would have been the most energetic segment of the event. Later portions of the eruption while energetic would have been less so. Some of the material from such an energetic eruptive event would have achieved Mars orbit. The material in orbit would have sorted itself by size/mass achieving layers of orbiting material at various heights based on size/mass. Over time the orbit of this material would have decorated due atmospheric drag resulting in a layers of material accumulating on the surface by size/mass. Ralph Nesbitt |

No, the rocks were ejected by a large impact event and not by vulcanism. The rocks were formed volcanically and then later blown off the surface and into solar orbit when a large meteoroid or asteroid hit Mars in the distant past. -- David W.

How about some sort of hypothesis regarding ejecta from the Hellas event? I haven't seen much about it in science essays, except that it rated about 1000 trillion tons of TNT; 100 miles across, travelling at 36,000 mph. It may even have passed clean through, emerging at Aetheria. Or maybe Aetheria is a bruise from the Hellas impact, some sort of collapsium. Is that what pulled the plug on the Martian Sea? One can even see the possibility of a polar shift on the MOLA topographic globe. |
