Shifting Sands on Mars formed Layered Structure seen by NASA's Curiosity Rover
NASA's Mars Exploration Rover Curiosity has revealed layered rock formations on the planet, spanning billions of years. These strata exhibit distinct characteristics indicative of various geological processes shaping Mars's surface over time.
Erosional events carved canyons and fragmented bedrock, evident in the presence of angular fragments within certain layers. Volcanic eruptions deposited ash and lava flows in far past period of Mars, as indicated by the distribution of basalt and rhyolite samples. Variations in their proportions suggest fluctuations in volcanic activity throughout Martian history. Subsequently, sediments accumulated in ancient lakes, forming these layered deposits.
Curiosity's Sample Analysis at Mars (SAM) instrument points to a past underground activity on Mars. The abundance of iron oxides, particularly hematite, increasing from lower to upper layers, hypothetically suggests prolonged interaction with water (in past). Geochemical modeling based on iron oxide distribution indicates the potential for shallow liquid flows.
