Special Issue Information

Dear Colleagues,

In a sedimentary basin, temperature is one of the most critical parameters, since it controls several processes, such as mineral precipitation, diagenesis, the maturation of organic matter, and fluid circulation. In turn, the temperature attained in a basin is the result of the interplay among several sedimentologic, structural, tectonic, and geodynamic processes, which are specific for each sedimentary basin.

The reconstruction of the present and paleothermal gradient has a relevant impact on socioeconomic and anthropogenic activities. This is because temperature has a strong impact on the presence of georesources in sedimentary basins. This includes hydrocarbons and geothermal energy. Furthermore, temperature has implications for the potential for the temporary or permanent storage of energy and anthropogenic products such as heat, CO2, and nuclear waste.

This Special Issue aims at presenting an overview on reconstructing the temperature variation over time in sedimentary basins, to deeply understand their tectonostratigraphic evolution as well as the processes forming earth resources. In this issue, different approaches for reconstructing the paleotemperature will also be emphasized.

We welcome contributions from researchers in all fields of geosciences, applying different analytical methods to the study of worldwide active and fossil sedimentary basins. Multidisciplinary integrated approaches are greatly welcomed. The aim is to foster discussion on which the best procedures for better understanding the geological processes driving the tectono-thermal evolution of sedimentary basins and their surrounding regions are.

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).

The Cooper subregion within the central Eromanga Basin is the Swiss army knife among Australia’s sedimentary basins. In addition to important oil and gas resources, it hosts abundant coal bed methane, important groundwater resources, features suitable conditions for enhanced geothermal systems, and is a potential site for carbon capture and storage. However, after seven decades of exploration, various uncertainties remain concerning its tectonic and thermal evolution. In this study, the public-domain 3D model of the Cooper and Eromanga stacked sedimentary basins was modified by integrating the latest structural and stratigraphic data, then used to perform numerical basin modelling and subsidence history analysis for a better comprehension of their complex geologic history. Calibrated 1D/3D numerical models provide the grounds for heat flow, temperature, thermal maturity, and sediment thickness maps. According to calibrated vitrinite reflectance profiles, a major hydrothermal/magmatic event at about 100 Ma with associated basal heat flow up to 150 mW/m2 caused source rock maturation and petroleum generation and probably overprinted most of the previous hydrothermal events in the study area. This event correlates with sedimentation rates up to 200 m/Ma and was apparently accompanied by extensive crustal shear. Structural style and depocentre migration analysis suggest that the Carboniferous–Triassic Cooper Basin initially has been a lazy-s shaped triplex pull-apart basin controlled by the Cooper Basin Master Fault before being inverted into a piggy-back basin and then blanketed by the Jurassic–Cretaceous Eromanga Basin. The interpreted Central Eromanga Shear Zone governed the tectonic evolution from the Triassic until today. It repeatedly induced NNW-SSE directed deformation along the western edge of the Thomson Orogen and is characterized by present-day seismicity and distinct neotectonic features. We hypothesize that throughout the basin evolution, alternating tectonic stress caused frequent thermal weakening of the crust and facilitated the establishment of the Cooper Hot Spot, which recently increased again its activity below the Nappamerri Trough.
