The zone allows this mineral to precipitate at 5:1 or even 1:1 calcium to magnesium ratio.
One model for the formation of deposits of this mineral, the schizohaline model, (**)involves the creation of a mixing zone between fresh and ocean water. The zone allows this mineral to precipitate at 5:1 or even 1:1 calcium to magnesium ratio. Another model involves the removal of calcium via evaporate deposition in sabkhas, (*) both of which are solutions to this mineral's namesake problem. It can be distinguished from a similar mineral by the saddle shape of its crystals. For 10 points name this mineral that is the namesake of a mountain range in Italy and has the formula CaMg(CO3).
