“…To better understand depositional processes and palaeoenvironmental changes, a research project was initiated integrating facies, sequence, stable isotope and palynofacies analyses. Ruf et al (2005) provide an initial report based on few selected data points. The present paper covers a regional scale, utilizing an extensive data base covering the entire Swabian Basin with a particular focus on a number of proximal and distal locations.…”

“…Both bioherms terminate at the maximum fall after a phase of retreat and are covered by a thick marlstone with high total palynoclast abundance be enriched in palynoclasts by diagenetic overprint as carbonate dissolution may result in a secondary palynoclast concentration within the marly residue. However, these factors were largely eliminated by correcting the absolute palynoclast abundances for carbonate content (Ruf et al 2005). Increased palynoclast abundances in carbonate-rich intervals are probably due to other, presently not fully understood controls, for instance climatic factors such as fluctuations in humidity.…”

A multi-proxy study of deeper-water carbonates (Upper Jurassic, southern Germany): combining sedimentology, chemostratigraphy and palynofacies Abstract Deeper shelf carbonates are often composed of relatively monotonous successions with few diagnostic sedimentological characteristics. The Upper Jurassic of southern Germany provides a classical example for deeper ramp carbonate environments, dominated by limestone/marl sequences including conspicuous sponge/microbial bioherms. Sedimentological analysis was integrated with stable isotope (O, C) and palynofacies analysis in an attempt to reconstruct the dominant depositional controls (sea level, climate, nutrients) as well as to delineate genetic sequences and their stacking patterns. Small-scale (3-10 m thick), medium-scale (5-25 m thick) and large-scale (45-60 m thick) sequences could be recognised, which all share similar patterns and trends. Oxygen isotopes from bulk rock carbonate samples were interpreted as records of temperature trends which were related to climatically induced sea level fluctuations. A positive oxygen isotope trend (i.e., cooling and associated relative sea-level fall) in combination with increasing absolute palynoclast abundances (increasing proximality) are inferred to mark regressive hemi-sequences. Negative trends in oxygen isotopes (i.e., warming and associated relative sea-level rise) and a decrease in absolute palynoclast abundances (increasing distality) are interpreted to indicate transgressive hemi-sequences. In contrast to the smallscale sequences, the medium-scale sequences could be

Dariyan (Shuaiba) Formation is one of the main reservoir units in the Persian Gulf and South Western Iran. The microfacies and depositional environment of this formation is been investigated in the current study and influencing factors in reservoir characteristics have been discussed for Dariyan reservoir in the Soroush oil field. Facies analysis conducted on core and cutting samples indicated that Dariyan Formation is mainly deposited on a carbonate ramp setting with a shallow intra shelf basin. In addition, it has been demonstrated that facies changes reflect the main controls of the tectonic and climate (sea level fluctuations) during the deposition of these sediments. To determine the reservoir unites in this formation, 5 electrofacies were determined by neural network method that it is using different petrophysical logs (i.e. GR, PHIE and SWE). Using rock typing as the best way to establish an association between the various collected data (e.g. logs and cores) and geological descriptions 4 hydraulic flow units or rock types, determined on the basis of the Flow Zone Indicator (FZI) method in the Dariyan Formation of the Soroush field. Establishing a correlation between microfacies and rock types, the carbonate zones with moderate to good reservoir properties and also the intervals with the highest reservoir quality were determined.

The sedimentary succession of a Late Jurassic (Oxfordian to basal Kimmeridgian) carbonate ramp is described and interpreted. The study area is located in the central part of the Lower Saxony Basin in NW Germany, which forms part of the Central European Basin. Eight well-exposed and undeformed sections of the study area (Süntel area, Wesergebirge and eastern part of the Wiehengebirge) provide detailed information about lithofacies and lateral thickness variations. Biostratigraphically, the age of these sediments is poorly constrained. Twenty microfacies types are recognized that can be grouped into seven facies associations: (a) strongly bioturbated marlstones deposited near storm wave base (SWB), (b) foraminifera-rich wackestones, (c) wackestones and floatstones with biostromes and (d) bioclastic limestones deposited between SWB and fair-weather wave base (FWWB), (e) oolitic and iron-oolitic limestones and (f) siliciclastic sediments deposited above FWWB, and (g) lagoonal deposits. These facies associations characterize a storm dominated shallow mixed carbonate-siliciclastic ramp. Based on facies changes, quartz content, and gamma ray logs, the Korallenoolith Formation can be subdivided into a lower carbonate-dominated and an upper siliciclastic-dominated part, build up by different scales of small-to large-scale deepening-and shallowing-upward cycles. A preliminary correlation of measured outcrops of this formation is presented.
