The brine may be moved to the hydrate area either above or below this range. If, how ever, the brine has a density below 1.346, then less recovery of K in the carnallite-halite mixture may be expected. On the other hand, if the brine is above 1,352, then contamination of the carnallite-halite mixture with $0.; is greater.

The highest amount of halite in average is measured in series A and C, with a halite content of around 86–87% and 87–88%, respectively. Series B has an average halite content of 45% and a strong layering related to significant variations in the second-phase content within the same core sample, with up to 30% anhydrite and 15% polyhalite.

The facies interpretation of the Ariri Formation typically describes layers of tachyhydrite, carnallite, sylvite and anhydrite embedded in thick layers of halite. These representative sequences of rock salt are seismically simulated by creating an Earth model, wherein a stratum of bittern salts or anhydrite is embedded in a halite.
