This meteorite is dominated by the mineral olivine.
A Martian meteorite in cross-polarized light. Each grain is about half a millimeter across. – rocks that fall to Earth from asteroids or planets colliding together – only 385 or so stones came from the planet Mars.
The rocks themselves also preserve chemical information that indicates some of the major events on Mars happened early in its history., 4.5 billion years ago, from gas and dust that made up the early solar system. Then, very soon after formation, its interior separated out into a metallic core and a solid rocky mantle and crust.has acted to stir and homogenize its deep interior. To use a food analogy, the Earth’s interior is like a smoothie and Mars’ is like a chunky fruit salad.
When studied together, nakhlites and chassignites tell researchers several things about Mars. First, as the molten rock that formed them oozed to the surface and eventually cooled and crystallized, some surrounding older rocks melted into them.
