We'll soon know what kinds of crops we can grow on Mars! Bonus, the fruits will be already freeze-dried!

What does a pH of 8-9 do to the "missing carbonates" paradox? If there was liquid water on the surface of the Mars at some point of time and CO2 in the atmosphere, then pH 8-9 (in contrast to an acidic pH most of us expected) is ideal for precipitation of carbonates (e.g. limestone). Where are all those carbonates?
