Diverse, abundant and well-preserved mollusk fauna are here reported for the first time from eastern coast Makram area, where Upper Miocene (Tortonian) sediments of Dar Pahn Unit crop out, representing shoreface tidal influenced deposits composed mainly ligh-gray marls. Multiple articulated bivalves completely preserved gastropod bivalve shells indicate little or no transport at all original habitat assemblage. A total 313 specimens, which 271 correspond to gastropods, were identified only...
This study focuses on sedimentation patterns and paleoecological conditions during the Upper Miocene in Southeast Iran, specifically analyzing Rudig section. The was predominantly terrigenous occurred marine conditions, forming multiple shallowing upwards sequences comprising silty marl, siltstone, sandstone. analysis of molluscan shells from this period indicates minimal bioerosion, with encrusters represented solely by Balanus sp. low level encrustation suggests rapid brief exposure times....
A high diversity of larger benthic foraminifera (LBF) fauna is recognized from the Ilerdian-Cuisian sedimentary succession for first time Birjand region, Sistan Suture Zone eastern Iran. These are described in accordance with standard shallow zonation, placing considerable emphasis on biostratigraphic and microfacies analysis implications. Four zones (SBZ8 SBZ10-12) have been designated LBF horizons comprising index zonal markers such as Alveolina elliptica nuttalli (Davies), A. decipiens...
Despite belonging to an important time slice in the geological history, Eocene shallow-marine beds of Alborz region Iran have received little attention from researchers. We selected two stratigraphic sections (Mojen and Kalateh) ascribed Ziarat Formation as suitable representatives for current analysis, emphasising on their constituent microfacies paleoenvironmental implications. The biotic communities are characterised by larger benthic foraminifera (LBF), coralline algae, corals, bivalves...
Precise taxonomy and the chronostratigraphic calibration of Middle Eocene Alveolina from Central Iran is here undertaken Chah-Talkh section southern Sabzevar region (Central Iran). We have identified kieli, stercusmuris nuttalli along with new species ozcani n. sp. that we include into elliptica group. also found Nummulites uroniensis, obesus cf. verneuili associated calcareous nannofossils look reliable to make thoughtful correlations Shallow Benthic Zones (SBZ). The foraminiferal...
Virtual outcrop modeling has emerged as a tool for supporting geological field activities such mapping and stratigraphic investigations. Here we show how this technique can be used to support the detailed logging sampling with case history from Eocene carbonate platform succession exposed in Val Rosandra gorge, vicinity of city Trieste, NE Italy. The biostratigraphic analysis highlighted occurrence Shallow Benthic zones (SBZ) 10 12 planktonic E7/E8. An upwards-deepening trend, inner...
Babazadeh & Cluzel (2023) studied two stratigraphic sections from the Eocene deposits of southwest Shahrekord region (Zagros region, Iran). According to biostratigraphic ranges larger benthic foraminifera, authors suggested in total three assemblage zones assigned Ypresian-Bartonian and Bartonian. In a previous contribution, (2022) described new species agglutinated conical foraminifera framework Mahallat central Iran. It is demonstrated herein that identified both publications need...
Abstract The alveolinid taxa, found in three stratigraphic sections of Eocene shallow-marine successions the western Alborz (Baghdareh and Gheynarjeh sections) eastern Iran (Chenesht section) regions, have been studied to determine their systematics biostratigraphy for first time. rich assemblages these regions are correlated with coeval faunas (in shallow benthic zones) Tethyan province. 29 species alveolinids identified include: Glomalveolina lepidula, Alveolina ellipsoidalis, A....
Eocene larger benthic foraminifera including orthophragmines, nummulitids and alveolinids from the Jahrum Pabdeh formations in Zagros region are presented. The studied 20-m-thick stratigraphic interval contains, Asterocyclina Gumbel 1870, Nemkovella Less 1987, Orbitoclypeus Silvestri 1907, Discocyclina Nummulites Lamarck 1801, Assilina d'Orbigny 1826 Alveolina 1826. This foraminiferal assemblage testifies for shallow zones (SBZs) 15 to 17, which ranges middle Lutetian up early Bartonian....
The Eocene carbonates of the south Sabzevar region in central Iran hold a rich Alveolina assemblage.Nine species including A. globula, sp. 1, aff. regularis, globosa, pasticillata, laxa, pisiformis and cf. decipiens are identified through detailed analysis thin section. biostratigraphy obtained points to early Ypresian Shallow Benthic Zones SBZ6 partly SBZ7, indicating occurrence lower carbonate system. is correlated calcareous nannofossil biostratigraphy, assignable middle part NP10 Zone...
The present study deals with molluscan accumulations of the Sokolowia horizon, which is a key-bed in middle Eocene Kalateh section (Ziarat Formation, Eastern Alborz, Iran). age this “key horizon” at-tributed to Bartonian based on presence larger benthic foraminifera species such as Nummulites lyelli (D'Archiac & Haime), Orbitoclypeus zitteli (Checchia-Rispoli) and Asterocyclina stella (Gümbel) immediately below it. paleogeographic distribution occurrence from Tarim Basin eastern Central...
Nummulitid tests are recorded for the first time from an upper Lutetian limestone outcrop of Tihoieyeh section, exposed in southwestern Jiroft region central Iran. Detailed studies on their systematics and biostratigraphy resulted diagnosis three nummulitid taxa as Assilina exponens Sowerby 1840, Nummulites deshayesi D’Archiac Haime 1853 sp. cf. N. praelyelli. These larger benthic foraminifera associated with calcareous nannofossil assemblages assignable to SBZ16, NP16/CNE14 biozones.
Benthic foraminiferal assemblages dominated by Alveolina species from the Ypresian (Ilerdian-Cuisian) are studied herein numerous localities of Iran and Turkey. From these successions, highly diversified assemblage 58 alveolinid identified along with their detailed biostratigraphical application, which resulted in recognition eight shallow benthic zones (SBZ5-SBZ12). Our findings based upon distribution ranges Ilerdian-Cuisian sediments (Central Tethys) that considered to have a strong...
A rich larger foraminifera assemblage from the Eocene carbonates of south Sabzevar region (Now-Deh section) in central Iran indicates a late Ypresian to early Lutetian age. Nine species Alveolina d’Orbigny are studied for systematics and biostratigraphy. The includes A. minuta, decastroi, cremae, cremae elongata, decipiens ayrancensis, celali, rugosa, cuspidata, frumentiformis. We have also found nummulitids (genus Nummulites Assilina) orthophragmines identified as N. campesinus,...
