It all serves to support the previous findings I mentioned about Martian volcanoes dating back upwards of 3. The other reason for the massive size of Martian volcanoes is that Mars lacks active plate tectonics. For terrestrial volcanoes, by contrast, plate tectonics moves them away from their magma sources and brings their eruptions to an end.
The last piece of the puzzle for our Martian meteorites was where they came from. By investigating NASA satellite photos we found a potential candidate: a crater large enough to have ejected meteorites into space, but young enough to be consistent with the 11 million year ejection age, and on volcanic terrain.
As yet unnamed, the crater is km from the summit of the Our research work has underlined the significant differences in volcanic activity between Earth and Mars, but numerous secrets about these Martian wonders remain. The age of the most recent eruptions on Mars are also still subject to considerable uncertainty. Some of these secrets will continue to be unravelled through studying Martian meteorites, satellite images and new rovers. To truly understand the largest volcanoes in the Solar System, however, we will probably have to collect pieces of our neighbouring planet through human or robotic missions and bring them back to Earth.

The motion of the Pacific plate removes the Hawaiian volcanoes from the hot spots that formed them within a few million years. But Mars doesn't have plate tectonics. Instead, the volcanoes that form over hot spots remain in place, lava flows piling atop one another to the peaks ever higher.
In myth Mt. Olympus was the home and seat of power for the gods, making it an important site in Greek society. In much the same way, Olympus Mons rules over the surrounding landscape and exerts visible influence on its surroundings. A large region of terrain that looks like crumpled aluminum foil surrounds the mountain. This terrain, called the Olympus Mons aureole, was probably formed as the huge landslides that formed the scarps around the base of the mountain spread out around the surrounding plains.
Some of the aureole has been buried by subsequent lava flows, mostly on the eastern side of the mountain. The largest area of this terrain was named Lycus Sulci, while portions isolated by lava flows received their own names.
At the northern edge of Lycus Sulci, the terrain changes dramatically. The elevation rises and the fissures are fewer but deeper. The landscape is different enough that it has received its own name — Acheron Fossae.
