Abstract

The sedimentary pattern of the northern Tabas Block during the Jurassic period, apart from global sea-level fluctuations, was mainly governed by tectonic events of varying intensity and extent. These events took place during the Late Triassic (Early Cimmerian phase), Middle Bajocian (Mid-Cimmerian phase), Early Callovian, Late Oxfordian and Late Kimmeridgian/ Tithonian (Late Cimmerian phase). The importance and extent of these events and their influence on the facies pattern of the northern Tabas block are discussed. In this context the lithostratigraphy of the Jurassic strata in the northern Tabas Block is revised.
The stratigraphic position of the Badamu and Parvadeh formations is briefly discussed and three facies types of the Hojedk Formation, belonging to different sedimentary environments, are reported. The Middle and Upper Jurassic Magu Group is subdivided into three new and genetically related subgroups, Le. the Upper Bajocian to Middle Callovian Baghamshah Sub group, the Lower Callovian to Middle Kimmeridgian Esfandiar Subgroup and the Upper Kimmeridgian to Tithonian Garedu Sub group (Fig. 3). Furthermore the Qal' eh Dokhtar Formation is revised and three new formations, Le. the Sikhor Formation(Lower/Middle Callovian), Kamar-e-Mehdi Formation (Callovian to Lower Kimmetidgian) and the Korond Formation (Upper Oxfordian to Middle Kimmeridgian) are established. This new subdivision will considerably facilitate the applicabilityof the lithostratigraphic scheme to future work.
