2011-12-20  halite are consistent with precipitation caused by seepage reflux of highly saturated brines during deposition of the overlying rock salt interval. Later in burial history, relatively small quantities of early halite were dissolved locally and re-precipitated as indicated by inclusions of streaky solid bitumen within the late halite cements.

2011-12-1  Platy and hopper-shape crystals of halite from the 2nd evaporite member (Fig. 13a, b) are inferred to represent the early salt concentration stage in evolution of the Gachsaran Formation. This concentration stage likely occurred when seawater was shallow, allowing halite crystals to form at the air–brine interface (Melvin, 1991).

2018-4-28  Produces halite (salt) and gypsum deposits by chemical precipitation as concentration of solids increases due to water loss by evaporation. This can occur in lakes that have no outlets (like the Great Salt Lake) or restricted ocean basins, like has happened in the Mediterranean Sea or the Gulf of Mexico in the past.

Laminated, darker halite was interpreted to form in slightly deeper or more density-stratified brine pools by a combination of cumulate (surface-formed rafts) sedimentation and bottom growth. Facies relationships and fabrics indicate that bottom-grown fabrics in gypsum can form in slightly deeper water than bottom-grown fabrics in halite ...

Halite-clay interplay in the Israeli Messinian - NASA/ADS

Lateral facies changes between halite, anhydrite and shales can be traced. This is interpreted as contemporaneous sedimentation in giant marine salt ponds (halite and anhydrite) and in drowned desert valleys and/or salt-marsh coasts (shales with sabkha-like anhydrites). Another type of shale is that directly underflooring halite horizons.

2011-1-18  Based on the composition of brine inclusions in halite, the formation conditions of elementary sedimentation rhythms of rock salt were determined in facies zones of the Permian halogenic basin of the Caspian region. The distribution of structural types of halite was analyzed and the rate of brine condensation was estimated by calculating the K+ concentration coefficients during the ...
