“…Occurrence: Hemicyclammina sigali was described by Maync (1953) from the middle Cenomanian of the Constantine Province in Algeria. This species is recorded in Portugal by Hart et al (2005), Italy (Simone et al, 2012), Turkey (Bignot and Poisson, 1974), Iran (Shirazi, 2009), Syria (Mouty et al, 2003), Jordan (Weidich and Al-Harithi, 1990), and Brazil (Berthou and Bengtson, 2007).

“…Compared to the biochronozones of the Tethyan realm according to von Salis in Hardenbol et al (1998), the biozones CC 9, CC 10 and CC 11 have been subdivided based on the first occurrences of Eiffellithus turriseiffelii, Microrhabdulus decoratus and Quadrum gartneri. Benthic foraminifers have been studied in thin-sections and in washed residue of marl and clay samples, and they are mainly classified after Hamaoui and Saint-Marc (1970), Saint-Marc (1974), Schröder and Neumann (1985), Weidich and Al-Harithi (1990), Koch (1968), andAl-Rifaiy et al (1993). Some larger foraminifers are biostratigraphically indicative and enable subdivision of the Cenomanian succession (compare 2004).…”

We present a comprehensive facies scheme for west-central Jordan platform deposits of upper Albian to Turonian age, discuss Cenomanian and Turonian carbonate cycles, and reconstruct the paleogeographic evolution of the platform. Comparisons with adjacent shelf areas (Israel, Sinai) emphasize local characteristics as well as the regional platform development. Platform deposits are subdivided into fifteen microfacies types that define eight environments of deposition of three facies belts. Main facies differences between Cenomanian and Turonian platforms are: rudist-bearing packstones that characterise the higher-energy shallow subtidal (transition zone) during the Cenomanian, and fossiliferous (commonly with diverse foraminifer assemblages) wackestones and packstones of an open shallow subtidal environment. On Turonian platforms high-energy environments are predominantly characterised by oolithic or bioclastic grainstones and packstones, whereas peritidal facies are indicated by dolomitic wackestones with thin, wavy (cryptmicrobial) lamination. Rhythmic facies changes define peritidal or subtidal shallowing-up carbonate cycles in several Cenomanian and Turonian platform intervals. Cyclicities are also analysed on the base of accommodation plots (Fischer Plots). High-frequency accommodation changes within lower Cenomanian cyclic bedded limestones of the central and southern area exhibit two major 'cyclic sets' (set I and II) each containing regionally comparable peaks. Accommodation patterns within cyclic set II coincide with the sequence boundary zone of CeJo1. The lateral and vertical facies distributions on the inner shelf allow the reconstruction of paleogeographic conditions during five time intervals (Interval A to E). An increased subsidence is assumed for the central study area, locally (area of Wadi Al Karak) persisting from middle Cenomanian to middle Turonian times. In contrast, inversion and the development of a paleo-high have been postulated for an adjacent area (Wadi Mujib) during late Cenomanian to early Turonian times, while small-scale sub-basins with an occasionally dysoxic facies developed northwards and further south during this time interval. A connection between these structural elements in Jordan with basins and uplift areas in Egypt and Israel during equivalent time intervals is assumed. This emphasises the mostly concordant development of that Levant Platform segment.

“…The washed-out specimens were compared with those from previous records of Jordan (e.g. Koch 1968;Basha 1979;Weidich and Al-Harithi 1990;Al-Rifay et al 1993). Six species of larger benthic foraminifers are used to distinguish the Cenomanian deposits (Fig.…”

“…Wetzel and Morton 1959;Nazzal and Mustafa 1993), bivalves (Aqrabawi 1993), echinoids (Bandel and Geys 1985), and foraminifers (e.g. Basha 1979;Al-Rifaiy and Cherif 1987;Al-Rifaiy et al 1993, Weidich andAl-Harithi 1990). Comparisons with biostratigraphic records from adjacent countries (Egypt: Abdel-Kireem 1988;Shahin and Kora 1991;Orabi 1992;Israel: Freund and Raab 1969;Lewy et al 1984;Lebanon: Hamaoui and Saint-Marc 1970) allow to improve the regional correlation of the Cenomanian-Turonian succession and the paleogeographic reconstruction, the oceanographic settings and the timing of geological events.…”

We studied upper Albian to Turonian shallowmarine shelf deposits (Ajlun Group) of west central Jordan along a NNE-SSW running transect. The carbonate-dominated succession includes few siliciclastic intercalations, claystones and shales, and can be subdivided into five formations. The Naur, Fuheis and Hummar Formations of upper Albian to upper Cenomanian age represent shallow subtidal to supratidal platform environments. The uppermost Cenomanian to middle Turonian Shueib Formation includes deeper water deposits of the inner/mid-shelf and locally TOC-rich black shales. Shallow-marine platform environments once again dominate the Wadi As Sir Formation (middle-upper Turonian). A new multibiostratigraphic framework is based on ammonites (mainly of the middle Cenomanian rhotomagense Zone to the middle Turonian woollgari Zone) and calcareous nannofossils (biozones CC 9-CC 11), supplemented by benthic and planktonic foraminifers and ostracods. It forms the base of a sequence stratigraphic subdivision, containing eight sedimentary sequences (S1-S8), which are separated by four Cenomanian sequence boundaries (CeJo1-CeJo4) and three Turonian sequence boundaries (TuJo1-TuJo3). This scheme allows the correlation of the platform succession from distal to proximal shelf areas in contrast to previous correlations using lithologic units. Furthermore, comparisons between the platform successions and sequence patterns of west central Jordan and those from neighbouring areas allow to differentiate local, regional, and global controlling factors of platform development within the study area.
