However, there does not appear to be convection in the mantle. Presently Mars shows little geological activity. The elemental composition of Mars is different from Earth's in several significant ways. First, Martian meteorite analysis suggests that the planet's mantle is about twice as rich in iron as the Earth's mantle.
On Earth, vast volcanic landscapes are called large igneous provinces (LIPs); such places are sources of nickel, copper, titanium, iron, platinum, palladium, and chromium. [4] [23] Mars's Tharsis region, which contains a group of giant volcanoes, is considered to be a LIP.
The surface geology of Mars is somewhere between the basalt or andesite rocks on Earth. This led to the formation of minerals similar to what is found on Earth. The presence of iron oxide gives the surface the “rust” color that is associated with Mars, the Red Planet.
The NASA Perseverance rover may have found a pivotal clue that’s central to its mission on Mars: geological evidence that could suggest life existed on the red planet billions of years ago.
Martian spherules (also known as hematite spherules, blueberries, & Martian blueberries) are small spherules (roughly spherical pebbles) that are rich in an iron oxide (grey hematite, α-Fe 2 O 3) and are found at Meridiani Planum (a large plain on Mars) in exceedingly large numbers.
In 2022, a study of the same zircon grain found it had been “shocked” by a meteorite impact, marking it as the only known shocked zircon from Mars. On Earth, zircon is very common and found in ...
There appear to be huge reservoirs under Mars, scientists have said. Evidence suggests that there are vast lakes of liquid water under the surface of the red planet, according to a new study.
[31] [32] Mars has twice as much iron oxide in its outer layer as Earth does, despite their supposed similar origin. It is thought that Earth, being hotter, transported much of the iron downwards in the 1,800 kilometres (1,118 mi) deep, 3,200 °C (5,792 °F ), lava seas of the early planet, while Mars, with a lower lava temperature of 2,200 °C ...
