| Abstract | ||
| Tarbur Formation at Ghaleh Mountain with 760m thickness is consist of two different types facies: terrigenous (in lower part) and calcareous (in upper parts). Terrigenous part consists of shale, marl, sandstone, conglomerate together with marine and benthic foraminifera. Litological and paleontological characteristics of this part, in general, show a barrier and siliciclastic shoreline environment. Calcareous section concluded of three parts: Lower part, middle part and upper part. Lower Calcareous part is consist of thin to medium bedded and middle part is consist of medium to thick bedded limestone which is rich of rudist and other benthic foraminifera. Upper part is consist of thick to very thick bedded limestone. In order to biostratigraphy of Tarbur Formation, 72 samples are achieved that based on identified foraminifera, we recognized biozone Orbitoides & Omphalocyclus Assemblage Zone in this formation. Based on identified foraminifera, Tarbur Formation age is Campanian- Maastrichtian in this section. | ||
