Yesterday, within the EGU (European Geosciences Union) General Assembly 2024, our new paper was presented under the title: "Triassic-Jurassic ophiolites of Dinaridic Ozren and Borja-Mahnjača massifs in Bosnia and Herzegovina: Mineralogy, geochronology, and P-T estimates from subducted sole." " It is a special honor for me that we presented our results, as a part of my PhD research, at the largest geoscientist conference in Europe and beyond. This is an indication that our hard work is going in the right direction. What is special for this work is the first geochronological data for these two massifs, which bring new information and (change) knowledge about the ophiolites of these areas. That is the charm of scientific and research work. Those interested can find out more at: https://lnkd.in/dMSPdA2Y

Happy to share my first Ph.D paper under supervision of Dr. Yaniv Edery, recently published in Hydrology and Earth System Sciences! Those interested in the fascinating subject of Self-organization in physical systems, please have a look! We simulate the interaction of transport with reversible dissolution–precipitation reaction in flow in porous media using the Lagrangian particle tracking approach and then investigate the results within the Thermodynamic framework (have to start with the capital T or else the professor in my first Thermo' course would take points off your grade!) to analyze and quantify the emergence of preferential flow paths in the medium as a manifestation of transport self-organization.

You are invited to the PhD Defense by Aslaug Clemmensen Glad On February 19, 2024, Aslaug will defend her PhD entitled "Natural Fractures in a Lower Cretaceous Chalk-marl Succession: characterization, Geomechanical Modeling and Impact on Reservoir Properties". Most carbonate reservoirs are naturally fractured. Fractures can significantly influence a formation's geological and geomechanical conditions and act as barriers or conduits for fluid flow. The Valdemar Field (Danish Central Graben) is the Danish North Sea's third-largest producing oil field. Its reservoir is confined to the Lower Cretaceous Tuxen and Sola Formations and comprises interbedded chalk and marl facies, resulting in low permeability and high porosity. Thus, production relies on the presence of natural fractures to enhance the local permeability and form connected networks and migration routes for fluid flow. Aslaug's thesis is a geological examination of natural fractures in the Valdemar Field, emphasizing fracture characterization, geomechanical modeling, and assessment of the impact on reservoir properties. Supervisors are Senior Researcher Hamid Nick, DTU Offshore, Associate Professor Ole Rønø Clausen, Aarhus University, and Researcher Frédéric Amour, DTU Offshore. Examiners are Reader Adriana Paluszny, Imperial College London, Dr. Ole Valdemar Vejbæk, OVV Geoscience, and Associate Professor Aleksandr Shapiro, Center for Energy Resources Engineering Learn more about the defense: https://lnkd.in/dUXzVYYK #DTUinnovation #PhD #geoscience #modeling #impactassessment #offshore DTU - Technical University of Denmark BlueNord ASA

I am pleased to share with you all that, I and my coauthors, Dr. M. Santosh, (School of Earth Sciences and Resources, China University of Geosciences, Beijing, China), Dr. M. Satyanarayanan (CSIR-National Geophysical Research Institute, Hyderabad), Prof. N. Srinivas (Department of Environmental Studies, GITAM University, Visakhapatnam), and Prof. Harish Gupta (Department of Civil Engineering, Osmania University, Hyderabad) have published a review paper in Geoscience Frontiers (Elsevier, IF: 8.9) recently on a vital subject – “Lithium: A review of applications, occurrence, exploration, extraction, recycling, analysis, and environmental impact“ Our article is an Open Access publication and can be downloaded using the following link: https://lnkd.in/gr2EceNX One of the Reviewers made very positive comments like the following during its review and revision time – The manuscript comprehensively reviews lithium, a critical metal resource of increasing importance in contemporary society. As the evaluation and exploration of lithium become increasingly crucial, this article provides an extensive overview of its properties, exploration methods, recycling techniques, and environmental impacts. By reading and gathering so much cutting-edge literature, the article serves as a guiding reference, akin to a dictionary, for future researchers. It represents a solid and comprehensive piece of work. The manuscript could be accepted after minor revisions. Prof. George J. Simandl, Critical Materials and Industrial Minerals Specialist, University of Victoria, Canada described this publication as an “Excellent Idea”

I am very excited to share that one of the papers from my Ph.D. project, in which I processed and analyzed the data and performed the inversions, was published in the Journal of Geophysical Research: Solid Earth. In this paper, we generated a 2-D electrical resistivity model from a profile of new magnetotelluric measurements in Central-Eastern Mongolia. This model was interpreted using information from seismic velocity models to shed light on major tectonic features within this region, such as the Mongol-Okhotsk suture zone and the Addatsag Ophiolite belt. These features are of scientific and economic relevancy since they are associated with the geological history of the Central Asian Orogenic Belt and host important mineral deposits of copper and gold. The dataset used in this study is part of a larger dataset covering most of Mongolia, which was used to generate a new national-scale 3-D electrical resistivity model of this region. This is the topic of future research. The full paper is available here: https://lnkd.in/eUEm_W4N

A study, published in Scientific Reports (2023), delves into the intricacies of quartz precipitation during low-velocity shear experiments. The motivation behind the study was to gain insights into the mechanisms that control the deformation rate produced by dissolution and precipitation, which is crucial for various fields including geology, materials science, and engineering. Key findings & takeaways from the study: 1. Quartz dissolution and precipitation were observed to occur under the experimental conditions, with precipitated quartz exhibiting a distinct blue luminescent signal and higher aluminum content. 2. The study demonstrated that the length scale of dissolution and precipitation is related to the spacing of sealed fractures in quartz grains. 3. The research provided evidence that fracturing plays a more significant role in the deformation process than previously assumed, particularly in the quartz-muscovite mixture. 4. The mechanical data from the experiments showed that the pure quartz gouge experienced stick-slip events followed by stable sliding, while the quartz-muscovite mixture exhibited stable sliding with a final friction coefficient of 0.32. Highlight: Delmic’s SPARC Compact system was utilized in the study to capture high-resolution false-color SEM-CL images. This was instrumental in visualizing the microstructural features of the experimental material, particularly the precipitation patterns and the role of aluminum in quartz grains during deformation processes. #Geology #MaterialsScience #MicrostructuralAnalysis #QuartzPrecipitation #Delmic #ScientificReports #ResearchUpdate

This week, on the Rio Oil and Gas 2024, I presented some findings of my PhD research advised by the professor Michael Holz. I discussed structural controls on the turbidites in the Ceará Basin and the implications for the exploration of the Brazilian Equatorial Margin. Turbidites are strongly influenced by the basin floor geometry and there are several examples around the world of structural controls on their distribution. In this presentation, I pointed out this influence may be presented also in the Ceará Basin. I would like to thank Eliis for providing the academic license of PaleoScan South America and also the GAIA - UFBA for supporting my research. #rog #brazilianequatorialmargin #cearabasin #seismicgeomorphology #turbidites
