This is an example of a thick-laminated, evenly-stratified rock type that forms stratigraphically beneath cross-bedded sandstones regarded as ancient river deposits. These rocks are interpreted to record sedimentation in a lake, as part of or in front of a delta, where plumes of river sediment settled out of the water column and onto the lake floor.
Yes, NASA has confirmed the presence of water on Mars. In 2015, they announced the discovery of hydrated salts on the planet's surface, which can only form in the presence of liquid water.
It is estimated that there is a significant amount of water on Mars, with some sources suggesting that the planet may have once had a large ocean covering a third of its surface. However, the exact amount of water currently on Mars is still being studied and is not yet known for certain.
The discovery of water on Mars is significant because it suggests that the planet may have once been habitable for microbial life. It also opens up the possibility for future human exploration and potential colonization of the planet.
The sediment pictures taken by NASA's Mars rovers show us the geological history of the planet and provide valuable information about its past environments. They also help scientists understand the composition and formation of the planet's surface.
NASA is currently researching ways to extract and use the water on Mars for future space missions. This could potentially save time and resources by not having to transport large amounts of water from Earth. However, more studies and technology development are needed before this can become a reality.
