For example, CaS[O.sub.4]-type acid (pH 2.0) waters flow at Mefite spring (electrical conductivity 5800 [micro]S [cm.sup.-1]), due to the interaction between groundwater and evaporites of Messinian age mainly made of gypsum [8].
(2008b) documented the widespread occurrence of evaporite calcitization, sulfur ore mineralization, and secondary gypsum (selenitic textures) crystallization that indicate that karst development in the region is dominated by hypogene processes where ascending, transverse speleogenesis is associated with both water and light hydrocarbons that have created complex secondary diagenetic alterations within the Castile Formation.
(1994) described Miocene dolomite and evaporites in six boreholes along the Musaffah Channel.
In the Fault and Evaporite districts, the topography over the steep slopes is bedrock-controlled, with minimal glacial diamicton and covered by primarily an Acadian hardwood forest.
The sedimentary rocks are composed from bottom to top of evaporites with shales and coal traces, calcarenites and calcilutites and biocalcarenites.
- Rum to spend a minimum of $250,000 in Year 1, drilling the lake to earn a 51% interest in Lake Mackay's potash and other evaporite minerals.
But because this part of the sulfur cycle was thought be minor in comparison to sulfate evaporite burial (which does not release oxygen), its effect on oxygen levels was also thought to be unimportant.
A new chapter on lakes broadens the perspective; otherwise, Part III addresses the mostly biochemically formed carbonates, the mostly chemically produced evaporites, and a new association called bioelemental sediments, which form via biological/chemical/oceanographic processes in the water column and include phosphate, chert, and iron-rich sediments.
Among their topics are the quaternary sedimentology of the Arabian/Persian Gulf and its geological impact; re-evaluating the Holocene evolution of Arabian coastal sabkas based on stable-isotope analysis 40 years after Shearman's first view; the geochemistry and nature of organic matter of the Pleistocene-Holocene carbonate-evaporite sediments of Al-Khiran in southeastern Kuwait; the role of bacterial sulphate reduction in carbonate replacement of vanished evaporites with examples from the Holocene, Jurassic, and Neoarchaean; salt tectonics and structural styles of the western High Atlas and the intersecting Essaouira-Cap Tafelney segments of the Moroccan Atlantic margin; and the petroleum exploration challenge of carbonates and evaporites of the Upper Jurassic Arab Formation in Abu Dhabi.
A large portion of Grizzly's 100% owned MAIM potash permits exist in close proximity to or directly contain areas that are underlain by potash bearing beds within the uppermost portion of the Prairie Evaporite Formation.
This type of terrain contains evaporite or carbonate rocks that have begun to dissolve away.
