“…This tilting is interpreted as being due to forced folding above the upward propagating PM Fault. The early delta (SP1) was therefore deposited above an active northwardtilting ramp, in a manner similar to that described by Young et al (2000) in the Gulf of Suez and to SP4, using a vertical exaggeration of two. SP1 is represented in two cross-sections, while there is no cross-section for SP2 as this small delta is hardly seen on the central cross-section (Fig.…”

“…Sheet-like geometries and the lack of channel forms suggest either deposition in wide, shallow low-sinuosity gravel rivers that occupied the subaerial fan delta top, or as unconfined high-magnitude sheet floods (e.g. Young et al, 2000). Occasionally preserved downstream-dipping low-angle inclined surfaces imply low-relief (?longitudinal) bars, on which gravel may have been accreted as diffuse gravel (bed load) sheets (Hein & Walker, 1977;Bridge, 2003); however, the preserved facies lack an openwork texture and well-developed grading profile typical of lower-stage plane beds (Bridge, 2003; see also Nemec & Postma, 1993).…”

In the Aegion to Kalavrita region of the Gulf of Corinth, Greece, Plio-Pleistocene syn-rift stratigraphy comprises a fluvial-dominated lower group and an upper group dominated by Gilbert-type deltas separated by an erosive unconformity. The lower group records substantial accumulation (1.3 km) of fluvial sediment across a broad area of fault-controlled grabens and half grabens, which was terminated by a marine transgression. The upper group records a great increase in accommodation space, the migration of the depocentre to the north and an increase in sediment supply. It is dominated by large gravel-rich systems that were sourced in the footwalls of active normal faults. The Vouraikos Delta is an exceptionally well-exposed Gilbert-type fan delta complex, which is > 800 m thick, with a surface area of 32 km 2 . It lies in the hangingwall of the Pirgaki-Mamoussia Fault and has been exhumed in the footwall of the Eastern Helike Fault. Preliminary palynological results from topset and pro-delta fine-grained facies and from lower group strata indicate that the Vouraikos Delta began forming some time before 1.1 Ma and was terminated soon after 0.7 Ma. These preliminary Early to Middle Pleistocene age estimates are coherent with published models of the uplift history of the Eastern Helike Fault. Sedimentation rates are thus estimated between 1.3 and 2 mm yr −1 . While the earliest delta infilled an incised palaeovalley, accommodation space was primarily tectonically controlled, first by an extensional forced fold and later by a system of major normal faults (Pirgaki-Mamoussia Fault and its splays). Several families of syn-sedimentary and late normal faults cut the delta. A listric growth fault controlled a large rollover anticline in the lowest stratigraphic package. The delta prograded (to the north-northwest) into water that reached depths of 200-600 m. Topset limestones associated with coastal conglomerate facies indicate that the delta built into a water body that was wholly or periodically marine. Internally, the Vouraikos Delta comprises five stratigraphic packages each characterized by a distinctive organization of topsets, foresets, bottomsets and pro-delta facies and bounded by major stratigraphic surfaces. These packages are tentatively correlated with regressive glacio-eustatic interglacial periods. The trajectory of the offlap break in the centre of the Vouraikos reflects early progradationdominated behaviour followed by increasingly aggradational behaviour.

The Quaternary period on the western coast of Turkey is studied using sedimentological features and geochronological age data of the Söke-Milet Basin (SMB), which is a subsidiary to the Büyük Menderes Graben (BMG). Here, for the first time, we geochronologically document the Early Pleistocene shallow marine fan-deltaic succession in the Fevzipaşa Formation (basin-fill unit of the SMB), 15 km inland of the current Aegean coast and 150 m above current sea level. The formation outcrops at the western end of the BMG. It comprises an alluvial fan to freshwater carbonate, shallow marine fan-deltaic and alluvial fan depositional packages separated by intrabasinal unconformities. Based on conventional sedimentary data, seven different facies associations (FA) have been distinguished in the Fevzipaşa Formation: (FA 1) hyperconcentrated flow-generated lower alluvial fan deposits, (FA 2) freshwater lacustrine carbonate deposits, (FA 3) prodelta deposits, (FA 4) shallow marine fan-delta slope deposits, (FA 5) nearshore sandy mouth-bar-type fandelta front deposits, (FA 6) alluvial fan-delta top deposits and (FA 7) hyperconcentrated flow-generated upper alluvial fan deposits. The shallow marine facies above the lower alluvial fan deposits, considered in conjunction with stratigraphical observations and geochronological and paleontological age data, suggest that a late Early Pleistocene transgression affected the Aegean region.

Turbidite sand stones de pos ited in rift set tings are cur rently among the main tar gets of hy dro car bon ex plo ra tion. How ever, the im pact of style of sed i men ta tion, cyclicity and diagenesis on res er voir qual ity of such sand stones is rel a tively poorly explored in the lit er a ture. The sedimentology, strati graphic ar chi tec ture, and diagenetic al ter ations of deep ma rine sand stones of the Miocene Nutaysh Mem ber of the Burqan For ma tion in the Midyan area (Saudi Ara bia) are de scribed based on num ber of mea sured sedimentologic sec tions, lithofacies iden ti fi ca tion in the field and lab o ra tory stud ies. Three lithofacies types are here iden ti fied in the mea sured sec tions. These are from bot tom to top: (1) "lithofacies A" con sist ing of mas sive to thickly-bed ded, coarse-to-very coarse-grained sand stone and con glom er ates; (2) "lithofacies B" con sist ing of well-bed ded, coarse-to-me dium-grained, well-sorted sand stone, and (3) "lithofacies C" con sist ing of thin-bed ded, fine to very fine-grained, cur rent-rip pled sand stone, bioturbated shaley siltstone and marl. The main diagenetic pro cesses in the sand stones in clude the for ma tion of grain-coat ing smectite and rhombic do lo mite. Small amounts of ce ments in clude the for ma tion of authigenic kaolinite and cal cite. The res er voir qual ity is an tic i pated to have been pre served un der the trans for ma tion of smectite to deep burial illite, which is be lieved to pre vent for ma tion of quartz ce ments.
