![Probertite lithofacies. Polished slabs. Bars are 1 cm. A) Small radiating aggregates of probertite within tuffaceous matrix. B) Nodular lithofacies of probertite (light-brown tone). Host material is a mixture of fine-grained probertite and micronodules of the same mineral. Decussate, dark-colored, prismatic porphyroblasts are of replacive hydroboracite. C) Intraclastic-nodular lithofacies of probertite (light-brown tone). D) Flowage-like structure of probertite (light-brown) (upper half of the picture). The original lithofacies could have been nodular. The lower half of the picture is made up of siliciclastic matrix.]()
![Probertite lithofacies (light-brown tone). Polished slabs. Bars are 1 cm. A) Alternation of diffusely laminated lithofacies of probertite (dark material) and discontinuous carbonate beds with nodular and intraclastic textures (white material). The growth of the carbonate components replaces or displaces probertite. B) Laminated lithofacies of probertite. The laminae exhibit different tonalities depending on the content in fine siliciclastic matrix. Some laminae are homogeneous, whereas others show fabric formed of micronodules and microbundles. Some euhedral, replacive crystals of hydroboracite (dark tone) are present. C) Mixed lithofacies of probertite, which is composed of alternation of probertite laminae and flattened nodules. Note that some of the bigger nodules in the upper half of the picture displace or disturb the laminae. Few euhedral crystals of replacive hydroboracite are present. D) Upwards gradation from laminated lithofacies to banded-nodular lithofacies of probertite.]()
![Lithologies others than probertite and glauberite (polished slabs). ca, carbonate; pr, probertite. Bars are 1 cm. A) Alternation of tuff, carbonate, and probertite laminae. B) Carbonate laminae (dolomicrite; white, central horizon) interbedded within overlying probertite and underlying probertite–glauberite. Note the complex lithofacies of the carbonate horizon (deformed laminae, broken fragments of laminae, nodules). C) Radiating aggregates of colemanite macrocrystals. D) Radiating aggregates of colemanite formed by crystal plates and macrofibers. Sediment matrix is present.]()
![Lithofacies and stratigraphic correlation of the evaporitic successions in the two studied boreholes. The base of the H3 halite unit is taken as the datum. The carbonate distribution in the units is indicated. The types 1 to 4 of glauberite–probertite alternations indicated in units G4 and G6 are representative but not exclusive; these types are as follows: (1) laminae of probertite (various lithofacies), and medium- to coarse-grained, thin-to-thick beds of glauberite; (2) thin-to-thick beds of probertite (various lithofacies), and fine- to medium-grained laminae of glauberite; (3) probertite laminae (various lithofacies), and fine- to medium-grained, thin beds of glauberite; and (4) thin beds of probertite (various lithofacies), and fine-grained laminae of glauberite.]()
![Details of glauberite–probertite alternations (polished slabs). Bars are 1 cm. A) Alternations between thin beds of diffusely laminated probertite and thin beds of medium- to coarse-grained glauberite. The glauberite thin beds are discontinuous and are mostly formed by crystal clusters. The growth of the glauberite crystals displaces or disturbs the diffuse laminae of probertite. The yellow color of the glauberite crystals is due to partial replacement by realgar. B) Alternations between medium-grained, thin-to-thick beds of glauberite (central part, base and top of the picture) and thin beds of diffuse laminae of probertite. The thin beds of probertite contain discontinuous horizons and masses of replacive carbonate (white).]()

![Lithofacies and stratigraphic correlation of units H3 (B2: 541–570 m; B188: 349–373 m) and G4 (B2: 480–541 m; B188: 312–349 m) in the two boreholes studied. Cycles of probertite at the base and glauberite–probertite alternations at the top are present in the two boreholes, although precise correlation of these cycles in the two boreholes is uncertain. For instance: some cycles in one of the boreholes seem to subdivide into two or three smaller cycles in the other borehole. Only the cycles beginning with a thick probertite horizon can be correlated (cycle at 530 m in depth in borehole B2 and cycle at 340 m in depth in borehole B188). Symbols: prb, probertite; gb, glauberite; lam, laminites; alt, glauberite–probertite alternations; hal, halite. In the legend, “dark-gray nodular” refers to both the mosaic-nodular and the subvertically elongated-nodular lithofacies.]()

BSR refers to bacterial sulfate reduction activity. “Light-brown lithofacies” refers to different types of probertite lithofacies of this color; “dark-gray lithofacies” refers to both the mosaic-nodular and the subvertically elongated-nodular lithofacies. Symbols and colors as in Figures 13 and 14.]()
![Petrography of laminites formed by probertite (p) and glauberite (g) laminae. Horizons of siliciclastic matrix of less than 100 μm in thickness at the base of the glauberite laminae are not represented. Five complete microcycles of glauberite–probertite (II to VI), with thicknesses ranging from 4.3 mm to 1.5 cm, are shown. In the probertite terms, the laminae have thicknesses between 0.5 and 2.8 mm. The glauberite terms show a variable number of laminae and also variable thicknesses, although the thickness is on average lower than in the laminae of the probertite terms. In the glauberite laminae, the blocky-prismatic and blocky-mosaic (anhedral) textures predominate, but the aligned fabric is predominant in the basal siliciclastic horizons. Sedentary (subvertical) fabrics are also present, whilst imbricate fabrics are lacking; some blocky textures are graded.]()
![Laminated glauberite (polished slab, A), glauberite–probertite alternation (polished slab, B), laminites (polished slab, C) and photomicrographs of laminites (D, E). Bars (A to C) are 1 cm. A) Fine- to medium-grained, laminated glauberite. B) Alternation of thin beds of laminated probertite and thin beds of glauberite. Some crystals and small crystal clusters of glauberite occur within the probertite thin beds. Some probertite is included within the thin beds of glauberite. C) Laminites formed by the alternation of probertite (groups of laminae with clear tone) and glauberite (groups of laminae with dark tone). At the base of the upper half of the picture, a group of 10 or 11 laminae of glauberite is present. At the top of the photograph the glauberite laminae become thicker and show medium-grained crystals. D) Glauberite texture in the laminites: prismatic crystals from decussate to aligned with bedding. Some glauberite clusters occur within the glauberite laminae. Plane light. Bar (white) is 0.3 mm. E) Glauberite textures in the laminites: reverse grading in the transparent, central lamina of glauberite. Plane light. Bar (black) is 0.5 mm.]()
