However, the largest volcano on the planet, Olympus Mons, is thought to have formed when the plates were not moving. Olympus Mons may have formed just after the plate motion stopped. The mare-like plains on Mars are roughly 3 to 3.5 billion years old. [72] The giant shield volcanoes are younger, formed between 1 and 2 billion years ago.
Numerous attempts [3] [4] [5] have been made over the years to determine an absolute Martian chronology (timeline) by comparing estimated impact cratering rates for Mars to those on the Moon. If the rate of impact crater formation on Mars by crater size per unit area over geologic time (the production rate or flux) is known with precision, then ...
The most conspicuous volcanoes on Mars are located in Tharsis and Elysium. Geologists think one of the reasons volcanoes on Mars were able to grow so large is that Mars has fewer tectonic boundaries in comparison to Earth. [64] Lava from a stationary hot spot was able to accumulate at one location on the surface for many hundreds of millions of ...

Pavonis Mons / p ə ˈ v oʊ n ɪ s ˈ m ɒ n z / [2] (Latin for "peacock mountain") is a large shield volcano located in the Tharsis region of the planet Mars.It is the middle member of a chain of three volcanic mountains (collectively known as the Tharsis Montes) that straddle the Martian equator between longitudes 235°E and 259°E.
The team suspects the bedrock was broken by an impact that occurred when a celestial body slammed into Mars 3.9 billion years ago, creating a 745-mile-wide (1,200-kilometer) basin that scattered ...
The volcano's caldera is named Apollinaris Patera; [2] this name formerly applied to the whole edifice. Apollinaris Mons is about 5 kilometres high with a base about 296 kilometres in diameter. [ 3 ] [ better source needed ] On the top of this volcano is a caldera about 80 km (50 miles) in diameter.
