Yes, at least some water on Mars was salty. In Nakhla,
halite (NaCl) is found in cavities, associated with iron carbonate
(siderite) and calcium sulfate (gypsum). It seems pretty sure
that the salt is Martian.

Subject: [meteorite-list] Any evidence salt water

Any evidence of salt water on mars?
Look what I read
" In 1998, two rocks zoomed through the Earth's atmosphere.
 One plopped down in Monahans, Texas, near some boys
 playing basketball. The other landed in Morocco, in a town

 called Zag.

 upon review by scientists from NASA
 and other institutions, the Zag and Monahans meteorites
turned
 out to have something special: water.

 When cracked open, the meteorites exhibit a purple area,
 which turned out to be ordinary table salt, sodium
chloride.
 Cosmic rays had turned the area purple. Upon closer
 inspection, scientists found droplets of salty water in
the purple.
 Zag and Monahans are of the most common type of meteorite
 that hits Earth, called chondrites. Scientists believe
both came
 from the same parent asteroid.

 The existence of water on the meteorites suggests that
water,
 or evidence of water, may be present on many more
meteorites
 that fall on Earth. If this is the case, water may not be
as rare in
 the solar system as many scientists suggest"

Thanks John Reed
