Glauconies are typically sand-sized and ellipsoidal green pellets in shape that have an earthy or lustrous appearance and is one of the major components of all siliciclastic facies in the Aitamir Formation. Studies of glaucony in this Formation led to identification of two types (allocthonous and autochthonous). Based on maturation, the glauconies in the Aitamir Formation can be divided  into slightly evolved, evolved and highly evolved. Study of cutting samples from Gonbadli well-9 and Khangiran wells-6 and 35 show that morphology of glaucony is useful for reservoir potential quality assessment. Rate of compaction and types of grains associated with glaucony can control the morphology of glaucony and it’s effect on reservoir quality. Glauconies in the Aitamir Formation are autochthonous and   types II and III. Therefore these sandstone units have suitable reservoir potential. This study showed that the morphology of glaucony can be used for evaluation of reservoir quality.
