Olivine is a marker for the lack of water because it easily decomposes in the presence of water. Sulfate was found, and it needs water to form. Wishstone contained a great deal of plagioclase, some olivine, and anhydrate (a sulfate). Peace rocks showed sulfur and strong evidence for bound water, so hydrated sulfates are suspected.

It is widely accepted that Mars had abundant water very early in its history, [92] [93] but all large areas of liquid water have since disappeared. A fraction of this water is retained on modern Mars as both ice and locked into the structure of abundant water-rich materials, including clay minerals ( phyllosilicates ) and sulfates .
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life. ‘Black Beauty’ was found on ...
This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep. [1] [2]
Curiosity's hard work is once again paying off by turning up evidence that liquid water quite likely exists on Mars at this time. A paper published in Nature Geoscience reveals that data collected ...
Scientists at Australia’s Curtin University made the discovery while studying a famous Martian meteorite — nicknamed “Black Beauty” — that was found in the Sahara Desert in 2011. The ...

Scientists discovered signs of an ocean's worth of liquid water miles below Mars' surface. The findings, based on Marsquake measurements by NASA's InSight lander, could help solve a mystery.
