Permian rocks predominantly consist of limestones, shales and evaporites. Shallow shelf seas and epicontinental seas existed in which evaporites and limestones were deposited. On top of this older basement Permian evaporites and Mesozoic limestones were deposited. Common seals include evaporites, chalks and shales. Carnallite minerals are mineral sediments known as evaporites. There are four primary types of sedimentary rocks&colon; clastics, carbonates, evaporites, and chemical. The mountain consists of shallow marine sedimentary rocks, which includes limestone, marl, and evaporites. Conversely, carbonates, evaporites and well-sorted sandstones have very low vitrinite contents. Group one are the pre-Permian basement rocks, a sedimentary sequence of clastics, carbonates and evaporites. Rapid sedimentation of clastics, carbonate platforms and shelves, and evaporites proceeded synorogenically. The evaporites of the area formed more unusual "salt anticlines" or linear regions of uplift. Sulfate minerals commonly form as evaporites, where they precipitate out of evaporating saline waters. MVT deposits commonly lie in close proximity to evaporites and/or beneath unconformities. MVT deposits commonly lie in close proximity to evaporites. These are mined industrially as evaporites, such as borax and kernite.
