Abstract A regional sequence stratigraphic model is proposed for the Oligo-Miocene Asmari and Pabdeh Formations in the Dezful Embayment of SW Iran. The model is based on both new detailed sedimentological observations in outcrops, core and well logs, and an improved high-resolution chronostratigraphic framework constrained by Sr isotope stratigraphy and biostratigraphy. A better understanding of the stratigraphic architecture distinguishes four, geographically separated types of Asmari reservoirs. Three Oligocene sequences (of Rupelian, early Chattian and late Chattian age) and three Miocene sequences (of early Aquitanian, late Aquitanian and early Burdigalian age) have been distinguished, representing a period of 15.4 Ma. The stratigraphic architecture of these sequences is primarily controlled by glacio-eustatic sea-level fluctuations, which determined the distribution of carbonates, sandstones and anhydrites in this sedimentary system. Tectonic control became important in the Burdigalian with a regional tilt down towards the NE. The lithological heterogeneity, the complex geometries, and both early and late diagenetic alterations are the basis for a classification of four main stratigraphic reference types for the Asmari Reservoirs: Type 1, sandstone dominated; Type 2, mixed carbonate-siliciclastic; Type 3, mixed carbonate-anhydrite; and Type 4, carbonate dominated. The sequence stratigraphic model predicts how and when these types change laterally from one to another.

(a) Formation boundaries are projected onto the resistivity model to compare the results from AMT investigation with the geology. The anomalous conductive zone in the centre of profile t1 should be noted. To provide more information about this zone, 500 m of core boring is proposed at the location of BZ-15 (between stations t1-26 and t1-27). (b) Water inflow and H2S seepage into the tunnel during the drilling programme. It should be noted that the highest amount of H2S seepage into the tunnel is related to the anomalous conductive zone, whereas the highest amount of water inflow into the tunnel is located in the fractured part of the Pabdeh Formation (in the vicinity of faults F2 and F1) and at the conjunction of the Pabdeh and Asmari formations.

Overview of the scar of the Seymareh rock avalanche on the NE flank of the Kabir Kuh anticline. (a) Panoramic view of debris and distant view of scar from the debris limit along the plunging nose of Kuh Dufarush (c. 14 km from the upslope limit of the sliding surface). The lateral limits of the scar are visible on the skyline, marked by vertical arrows. The distance between the lateral limits is 15.5 km. Utility poles on the debris in the foreground are c. 12 m high. (b) The NW lateral scarp, consisting of Asmari Limestone, is visible on the skyline. Various basal sliding surfaces are visible in the middle to near foreground and coincide with bedding surfaces of limestone beds (mean dip c. 22°) in the Pabdeh Formation. The most dominant sliding surfaces represented are sliding surface 1 (foreground, lower slope), sliding surfaces 3 and 4 (middle ground, upper slope) and sliding surface 2 (background, upper slope). Debris at right consists of disaggregated mudrocks of the Pabdeh Formation. Parts of the scar have been deeply eroded by stream action since the landslide occurred (see incised gully at left).
