Geologic map of Mars

Posted to Maps  |  Tags: ,  |  Nathan Yau

The USGS released a more detailed geologic map of Mars, not just renderings based on rough models.

The USGS-led mapping effort reveals that the Martian surface is generally older than previously thought. Three times as much surface area dates to the first major geologic time period – the Early Noachian Epoch – than was previously mapped. This timeframe is the earliest part of the Noachian Period, which ranges from about 4.1 to about 3.7 billion years ago, and was characterized by high rates of meteorite impacts, widespread erosion of the Martian surface and the likely presence of abundant surface water.

Nice.
