Billion years ago. During the late Noachian period significant geological processes occurred on Mars such as volcanism crater formation and the possible formation of rivers and lakes. The original crater floor was covered by igneous rocks probably volcanic andor intrusive igneous rocks formed by the crystallization of magma embedded in the Earths crust and mantle followed by clastic sedimentary materials presumably of fluviodeltaic origin. Extrusive and intrusive igneous rocks Extrusive and intrusive igneous rocks. To date the rover has examined the crater floor frontal part upper fan and crater rim and collected Buy Email List successful cores of igneous and sedimentary rocks. Unlike meteorites and almost all returned samples from the Moon and asteroids out of rock cores are samples of unambiguous bedrock in situ found in their natural environment. Regolith collection is also possible. Regolith is the surface layer of crushed minerals rocks and dust that covers the solid rocky surface of a planet moon or asteroid. On planets and other celestial bodies that have an atmosphere regolith forms as a result of meteor showers wind and water erosion the process by which material on the Earths surface is broken down and moved by natural factors and other processes. However determining the orientation of the regolith is impossible not considered in this study. Lunar regolith Lunar regolith A core is obtained by drilling a well. The core contains information about the structure of rocks their composition density porosity and other important characteristics.
