The project is located within the Sabinas Basin that serves as depositional site for an approximately 6,000 m thick section of Jurassic to Cretaceous siliciclastic, carbonate, and evaporitic
Molecular isotopic characterisation of hydrocarbon biomarkers in Palaeocene-Eocene evaporitic
, lacustrine source rocks from the Jianghan Basin, China.
The spread of salinity values measured by microthermometry analyses supports a dominant meteoric origin of the fluid, which has either been mixed with saline fluids or enriched in salt due to the dissolution of evaporitic
There are several evaporitic
sequences in the Miocene.
Conditions may have been favourable for the formation of an evaporitic
environment during the Keila age, when the sea level dropped (Nestor & Einasto 1997).
stromatolicola from stromatolites in two evaporitic
lakes and a marsh in the Cuatro Cienegas basin, in central Coahuila, northern Mexico (Zamudio-Valdez and Reid 1990), L.
For example, there are inland hypersaline lakes in evaporitic
basins in the highlands of the Atacama Desert, a sub- tropical and extremely dry desert (24[degrees]30'S, 69[degrees]15'W) (Demergasso et al., 2004; Dorador et al., 2013), and in the Patagonia, between 39 and 53[degrees]S, an arid and semi-humid climate, and steppe-like landscape (Campos et al., 1996).
The results of this survey revealed the presence of a sandstone formation probably more than 300m thick at the core of the NE-SW anticlinal structure and the absence of an evaporitic
sequence or salt dome up to the depth of 275m.
The post-Triassic cover appears to be decolled from the evaporitic
Triassic formations, especially above the Sidi Fili and Ain El Orma basement faults.
It is well-known that, at different periods of history, glass was produced by adding a flux, composed of natron (term here adopted with the meaning of usually complex, often polyphase evaporitic
deposits rich in carbonates of sodium), or soda ash from the combustion of halophytic plants such as Salsola or Salicornia, or potash ash from the combustion of trees such as beech, birch, and oak, to quartz pebbles or quartz-limestone sand .
The Zohr prospect is characterised as a Lower-Middle Miocene Carbonate reservoir, hosting a biogenic gas accumulation within a tertiary source rock, which is sealed by the Messinian Evaporitic
complex (also known as the Rosetta Formation).
The relative long-lasting subaerial exposure and sharp facies change into an evaporitic
salt marsh or salt pan environment of the Keuper facies suggests that a relative sea-level fall and a Lowstand Systems Tract resulted over the upper boundary of the Muschelkalk sequence.
