Two major events centred at AD 1 and AD 900 are seen in the sulphur content record - used as a proxy for evaporitic gypsum, and hence aridity - which appear to be broadly contemporaneous with the dramatic vegetation shifts at Marcacocha at AD 1-100 and AD 950-1050 [ILLUSTRATION FOR FIGURE 4 OMITTED].

The Hith Fm, like in Abu Dhabi to the south, is in an evaporitic facies in the west and is dolomitic in the east.
In Kuh-e-Surmeh section, Fahliyan Formation is placed above Hith evaporitic Formation with an unconformable boundary and below Gadvan Formation with a conformable boundary.
These evaporitic systems, which have high salinities (>seawater), high alkalinities, and pHs ranging from neutral to over 10, provide a natural laboratory to investigate the microbial metabolisms, processes and signatures of microbial mat systems.
Oil shale is mineralogically very complex because the mineral suite includes clastic, carbonate, and evaporitic minerals, some nearly unique to the saline lake environment, as well as the kerogen.
The Rus, like the older Hith anhydrite, loses its evaporitic character to the east.

Evaporitic facies were developed mainly in the marginal lacustrine zones while carbonate and lignite deposits were dominant in inner lacustrine areas [25].
Near-surface diagenetic settings are those within a few metres of surface, where the pore fluids are essentially unaltered and of meteoric, brackish, marine, or evaporitic origin.
These included high organic productivity, repeated regressive shoal conditions, anoxic lagoonal oil source rocks, and evaporitic seals.
In this paper we study the dolomitization of the Silurian carbonate sequence in eastern Lithuania by means of XRD, geochemical major and trace element analysis and stable isotope (518O and 513C) composition of dolomitic rocks in order to reveal the mechanisms of dolomitization, including distinction between meteoric, marine or evaporitic environment and possible dolostone precursor sediment.
