摘要：

The Late Permian to Early Triassic Khuff Formation of the United Arab Emirates is a 625-970 m thick sequence of shallow water carbonates (dolomites, limestones and dolomitic limestones with subordinate anhydrite). It can be subdivided into ten facies units distinguished on the basis of their depositional textures, that represent an overall regressive carbonate-evaporite sequence. Based on the paleoecology, sedimentary structures and lithology, four distinct depositional settings can be recognized: supratidal (sabkha), lagoon, shoal and shallow shelf. The Khuff Formation has both primary (interparticle) and secondary (dissolution vugs and intercrystalline) porosities.
