Studies of impact crater densities on the Martian surface [11] [12] have delineated four broad periods in the planet's geologic history. [13] The periods were named after places on Mars that had large-scale surface features, such as large craters or widespread lava flows, that date back to these time periods.
Geology of Mars. Generalised geological map of Mars [1] Mars as seen by the Hubble Space Telescope. The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology.
Martian Geologic Timescale. The Pre-Noachian period is a geological system and early time period on Mars marked by intense meteoroid and asteroid impacts, volcanic and tectonic activity, and the potential presence of surface or subsurface water. [1] The era holds significant importance in Mars' history as it witnessed the planet's formation and ...
The Amazonian is a geologic system and time period on the planet Mars characterized by low rates of meteorite and asteroid impacts and by cold, hyperarid conditions broadly similar to those on Mars today. [1][2] The transition from the preceding Hesperian period is somewhat poorly defined.
The Hesperian is a geologic system and time period on the planet Mars characterized by widespread volcanic activity and catastrophic flooding that carved immense outflow channels across the surface. The Hesperian is an intermediate and transitional period of Martian history. During the Hesperian, Mars changed from the wetter and perhaps warmer ...
Principles. The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [3] It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or ...

The Noachian is a geologic system and early time period on the planet Mars characterized by high rates of meteorite and asteroid impacts and the possible presence of abundant surface water. [1] The absolute age of the Noachian period is uncertain but probably corresponds to the lunar Pre-Nectarian to Early Imbrian periods [2] of 4100 to 3700 ...
