Gulneri Fm. is documented underlying the Kometan Fm. with an unconformable surface, while at the overlying it is limited unconformably by a Shiranish Formation. The formation is originated of limestone and dolomitic Lst., cherts nodules attend. We identified five nannobiozones, Micula staurophora Biozone (CC14); Reinhardites anthophorus Biozone (CC15); Lucianorhabdus cayeuxii Biozone (CC16); Calculites obscurus Biozone (CC17); Brosonia parca Biozone (CC18).
