1. Evaporites are considered sedimentary rocks and are formed by chemical sediments.2. Celestine and other bladed evaporite minerals may also form rosette clusters. 3. Restricted oceanic circulation in the west led to extensive evaporite formation. 4. A third process for ore deposition is as an evaporite . 5. Many of the halide minerals occur in marine evaporite deposits. 6. Secondary reactions can produce or consume leonite in evaporite deposits. 7. The massive evaporite deposits of the Michigan Basin were created during this period. 8. Evaporite deposits may contain potassium minerals such as carnallite.9. Later it became isolated and evaporites started to appear. 10. Shallow shelf seas and epicontinental seas existed in which evaporites and limestones were deposited.
