Special Issue Information

Dear Colleagues,

We would like to invite you to submit a manuscript to a Special Issue of Geosciences focused on integrated stratigraphic approaches to unravel the sedimentary record of carbonate platforms.

Shallow water carbonate platforms represent a major repository of the geological history of our planet. They document the response of neritic biota to environmental, climatic, and paleoceanographic modifications evidently expressed by characteristic biotic evolution and facies changes and, at the same time, they host a valuable record of carbonate-associated proxies of past ocean conditions. Furthermore, carbonate platforms are also an important target for petroleum exploration, hosting valuable reserves of fossil fuels. Establishing high-resolution age models is, therefore, the key to unlocking these precious geological archives. Unfortunately, the possibility to establish an accurate time framework for carbonate platforms evolution is often difficult due to the poor stratigraphic resolution attained using biostratigraphy alone. To overcome this problem, a combination of different stratigraphic techniques must be used and, in recent years, an increasing number of studies have been validating the accuracy of such an integrated approach.

This special issue aims to incorporate classical and modern techniques of stratigraphy aimed at improving stratigraphic resolution in carbonate platform sections through the integration of biostratigraphy, magnetostratigraphy, isotope stratigraphy, cyclostratigraphy, and sequence stratigraphy. Contributions dealing with stratigraphic intervals encompassing extreme events, like the end-Permian, end-Triassic, end-Cretaceous events and the Mesozoic OAEs are particularly encouraged.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Historically, Silurian pinnacle reef complexes in the Michigan Basin have been largely identified using 2D seismic with very little research on the reservoir characterization of these reefs using 3D seismic data. By incorporating a high-resolution 3D dataset constrained by a well-studied and data-rich paleoreef reservoir, the Puttygut reef, seismic attributes were correlated to petrophysical properties through machine learning and self-organizing maps (SOMs). A suite of structural and frequency-based attributes was calculated from pre-stack time migrated (PSTM) seismic data, with only a subset of them selected as SOM inputs. Structural attributes enhanced details in the reef but frequency attributes were overall more useful for correlating with reservoir quality. A strong relationship between certain combination percentages of attributes and certain sections of the reef with porosity and permeability was found after the SOM results were compared to wireline log and core analysis data. Areas with high permeability and porosity correlated with the average frequency and spectral decomposition at 29 and 81 Hz. Areas with high porosity and varying permeability correlated with the average frequency and spectral decomposition at 29, 57, and 81 Hz. Areas with intermediate porosity correlated with the average frequency and spectral decomposition at 29 and 57 Hz. The efficacy of the procedure was then demonstrated on two nearby reefs with very similar results. Full article
