Assessment tract permissive of mixed stratabound potash-bearing salt and halokinetic potash-bearing salt in Algeria-Libya-Morocco-Tunisia
|Deposit type||mixed stratabound potash-bearing salt and halokinetic potash-bearing salt|
|Basin type||marine rift basin|
|Geologic unit||Saliferous Units|
|Tectonic setting||divergent margin|
Upper Triassic-Lower Jurassic
|Notes:||Approximate area of potash-bearing salts and sulfates of the Saliferous Unit.|
|Known K sites?||Yes|
|Quality of information||E: Less than ten references with essentially no details or point information.|
|Assessors||Mark D. Cocker (USGS)|
|Qualitative assessment||R5: Very little information exists.|
|Tract delineation||The Saharan tract represents the extent of halite and sulfate salts within the Saharan evaporite basin. Original tract boundaries were approximated based on a figure from Turner and Sherif (2007, fig. 13), and were then modified based to include known potash and salt occurrences of the appropriate age. Geology from the African metallogenic map of Veselinovic-Williams and Frost-Killian (2003) was used to exclude areas where surface rocks were too old to host deposits.|
