Understanding the Origin of Salt Giants
Convenors: Francesco Dela Pierre (University of Torino, Italy), Tim Lowenstein (Binghamton University USA) and Luis Gibert (University of Barcelona, Spain)
A Salt Giant is a huge evaporitic body developed when oceanic basins are restricted from the global ocean during their initial formation or at the last stages of their existence in the Wilson cycle. The formation of a Salt Giant has global effects since it reduces the global salinity of oceans and decreases the freezing temperatures in marine polar areas. Salt Giants are formed in very short time intervals, affecting the structure and evolution of sedimentary basins and of the biota living there. In addition, Salt Giants have economic interest, since evaporitic rocks are the source of building materials such as gypsum, or of strategic elements for the development of our society, such as Na and K. Because of peculiar petrophysical properties of salt, similar to ice, thick saline deposits can develop particular deformation processes known as salt tectonics or halokinesis forming detachment surfaces, diapirs and minibasins that can play a key role in the genesis of hydrocarbon reservoirs.Different Salt Giants (n=18) have accumulated on Earth associated to the breakup and collision of continents, the oldest preserved is from the Neoproterozoic in the Amadeus Basin (>720 Ma), in Australia, and the youngest was developed during the Messinian times (6-5.3Ma) in the Mediterranean region. However, the interpretation of their origin and evolution is challenging, mostly because of the absence of modern analogs and of the variety of factors (tectonics, climate, biogeochemistry, etc.) that influence their formation. This multidisciplinary session welcomes any research related to sedimentology, stratigraphic architecture, tectonics, geochemistry, geophysics, geomodelling, paleoclimate, and geobiology related to modern or ancient evaporite deposits that can be used for the interpretation of Salt Giants.
