Facies analysis, depositional environments and palaecological conditions of the Lower Carboniferous carbonate ramp in the Sanandaj- Sirjan zone, Iran

F. Shirezade Esfahani; A. Bayet-Goll; N. Kohansal Ghadimvand; A. Kangazian; A. Akbari Mohammadi; M. Sadri

Volume 28, Issue 111 , May 2019, , Pages 289-300


  The carbonate successions (Tournaisian-Visean) exposed in the Tang-e-Darchaleh and Banarizeh sections from Sanandaj-Sirjan Zone (SSZ), Iran, have been used to generate a facies model. From the analysis of facies and their associations, four depositional zones are recognized on the Tournaisian-Visean ...  Read More

Facies analysis in transitional from Ordovician deposits (upper part of Shirgesht formation) to Silurian (lower part of Niur formation) in SW Kashmar, North of Tabas block

E Khazaei; M.H Mahmudy Gharaie; A Mahboubi; J Taheri

Volume 26, Issue 101 , December 2017, , Pages 111-126


  The studied section in SW Kashmar located in Tabas block of central Iran sedimentary - structural zone. According to field observations and petrography, two sets of siliciclastic and carbonate facies were distinguished. Three lithofacies were identified based on the field parameters such as lithology, ...  Read More
