This paper aims to (a) document planktonic foraminiferal fauna of the Parh Limestone from the outcrops exposed in Hanna Lake and Murree Brewery sections, (b) establish high resolution biostratigraphy on the basis of obtained assemblages, (c) compare recovered planktonic foraminiferal assemblages with previous studies conducted on the Parh Limestone and elsewhere in other parts of Tethys and (d) to assign depositional environments to Parh Limestone based on field and microfacies analysis.
Reservoir microfacies, resource distribution, and identification of low resistivity resource accumulations are urgent areas of research for this oilfield [7-10].
Four students of the Department of Applied Geosciences will receive scholarships, comprising course fees and accommodation, for the International Course on Carbonate Microfacies 2017 to be held at the University of Erlangen in Germany between 2 - 11 March 2017.
The sedimentary facies modeling is based on construction model (Li et al., 2013), under the guidance of sedimentary model, using the theory of Assign to closest point to plane interpolation for phase data, and take the result of interpolation as constraints to establish sedimentary microfacies model (Chong et al., 2011).
Microfacies: The matrix is mainly packstone with some local grainstone.
In this article one stratigraphic subsurface section was chosen and subjected to detailed microfacies analysis based mainly on the distribution of Oligo-Miocene foraminiferal assemblages.
In this study, 29 samples were studied from different levels of Amb Formation at its type locality which were used for microfacies analysis.
Abstract: The sedimentology of the early middle Cambrian, Jutana Formation was investigated from Khewra area, above PMDC Tourist Resort, Eastern Salt Range, District Chakwal, Pakistan to elaborate its microfacies and diagenetic settings.
Los objetivos fundamentales de este trabajo son la elaboracion de un analisis de facies y microfacies en esta sucesion transito, estudiando los factores estratigraficos y sedimentologicos que controlan la facies mineralizada del yacimiento de Salamon, asi como la caracterizacion isotopica de las calizas, comprobando si existe una senal isotopica que refleje dicho limite.
The siltstones with parallel bedding are mainly deposited in the distal bar microfacies. In contrast, the horizontal bedding can be observed in the dark mudstones, representing a low water energy environment [6].
