Abstract Palynofacies analyses were carried out on 272 core samples from two wells (GTP-17-SE and GTP-24-SE) in the Sergipe Basin, with the aim of reconstructing the paleoenvironments of the upper Aptian–middle Albian. For the palynofacies analysis the kerogen categories were counted and subjected to cluster analyses.

The uppermost Chhidru Formation and the lower part of the Mianwali Formation were sampled in the Amb Valley, Salt Range, Pakistan for the study of the particulate organic matter (POM) content in order to evaluate the depositional environment during the Permian–Triassic transition. The POM content was assigned to four distinct palynofacies (palynofacies

Palynofacies Analysis and Submicron Pore Modeling of Shale-Gas Plays
North American Unconventional Gas Conference and Exhibition, 2011Abstract The present study combines palynological applications with advanced microscopic techniques to characterize the Utica, Haynesville and Fayetteville shale-gas source rocks. This unprecedented approach could offer an alternative way to measure the total organic carbon (TOC) content using the 2D subsurface Scanning Electron ...

Development and multi-operator calibration of a standardised palynofacies analysis technique
2016This report presents the results of a project to develop and test a standard approach and criteria for palynofacies analysis. Palynofacies analysis is a palynological method of sedimentary depositional facies recognition. It is the study of all particulate organic matter recovered in a palynological assemblage, and can be used to reconstruct ...

Some Practical Aspects of Palynofacies Analysis
1995Much palynofacies work has been done as a secondary exercise within palynostratigraphic studies. Unfortunately, this often means that the samples were collected using a strategy that emphasizes standard sampling intervals and the selection of only those lithologies likely to be most productive in terms of palynomorph yield.

Abstract This study demonstrates the usefulness of palynofacies as a tool for characterizing the origin, transport, and settling of particulate organic matter preserved in fluvial plain sediments and its integration with diatoms for inferring past depositional environments. Palynofacies, diatoms, and organic geochemistry (S, C/S) data from a sediment
