Hi everyone,
Does anyone know of any current/previous research or manuscripts regarding the amount of evaporite required to mobilize an impure evaporite sequence, such as the Roan Group (DRCongo) or the Callanna Group (SAustralia)? I refer to mobilization as in evacuation/diapirism and impurities may include silciclastic, carbonate and/or volcanic rocks originally intercalated with evaporites such as halite, anyhydrite etc.
With the Gulf of Mexico and offshore Brazilian basins containing
relatively pure evaporitic sequences, these areas are outliers
(somewhat). It seems many impure evaporite sequences mobilize and behave in a similar fashion to nearly pure evaporite sequences, so I'm wondering if there is a cutoff point (and there must be) when the amount of impurities within an evaporite sequence exceeds the more mobile faction and mobilization becomes more difficult or non-existent.
Any help would be greatly appreciated!
Thanks for your time,
Thomas Hearon
