Summary: This study focuses on the uppermost Karoo Supergroup in southern Africa, documenting evidence of a humid phase and climatic changes during the Early Jurassic period. Facies changes in the studied interval provide insight into shifts in the ancient landscape and associated conditions. The findings suggest a transition from a dry desert setting to a wetter desert ecosystem, supporting a diverse biota during the Late Pliensbachian period.

Summary: This study presents a tool for generating near real-time interactive thermal maps of lava flows using free thermal data and open-source software. The tool was tested using statistical analysis and demonstrated high accuracy and minimal offset compared to official lava flow maps.

Summary: This paper investigates the controlling factors of the evolution of debris flows along the Jinjiang River, which is located in an active orogen. Remote sensing images, geological maps, and field investigations were conducted to determine the distribution of the lithologies, faults, and debris flows. The results indicate that the distribution of the huge debris flows is primarily controlled by either faults or boundaries between the sedimentary rocks and basalt.

Summary: This study evaluated the characteristics of intermediate mafic lava flows of the Yingcheng Formation in the Dongling area and their relationship with the reservoir properties. Various analyses were conducted, including the examination of drilling cores, thin sections, and SEM images, as well as well-logging and seismic attributes. The results showed the development of different facies with diverse well-logging and seismic responses. The facies architecture was divided into crater-proximal facies, medial facies, and distal facies, which could be identified through their seismic attributes. The physical properties and pore structure of the reservoir were assessed, and the reservoir quality was found to be best in the crater-proximal facies, which is the main target of oil and gas exploration.

Summary: The Amphibolitic rocks of the Tutak Metamorphic Complex have a U-Pb age of 56.08+/- 1.13 Ma and peak temperatures of 616 to 674 degrees Celsius. Geochemically, they are likely derived from sub-alkaline basaltic magma in a mantle source with enriched Nb and Sr depletion.

Summary: Stratigraphic forward modelling was used to simulate the deposition of Upper Cretaceous, Eocene and Oligo-Miocene source rocks in the Eastern Mediterranean Sea, showing that the source rocks in Upper Cretaceous and Eocene are mainly located along the Levant Margin and the Eratosthenes Seamount, while the Oligo-Miocene intervals have terrestrial organic matter contributing the most to the TOC content throughout the basin. The study also identified thermal maturation zones and petroleum generation timings in the respective source rock intervals.

Summary: In this study, basalt rocks from Mount Etna were analyzed using Fe-57 Mossbauer spectroscopy, X-ray diffraction, and X-ray fluorescence analysis. The presence of iron-bearing minerals and their magnetic nature were identified and quantified, with various minerals like magnetite, olivine, pyroxene, hornblende, hematite, and goethite found in the samples. X-ray diffraction and X-ray fluorescence provided additional structural and compositional analysis, revealing qualitative similarities and quantitative differences in the rock samples.

Summary: The study discusses the characteristics of metadolerites from the Paleo-Mesoproterozoic Shillong Basin in Northeast India. The data shows distinctive features of subduction-related magmatism and reinforces a tectonic setting of a back-arc basin. The Shillong Basin is inferred to represent a back-arc rift region.

Summary: This study explores the similarities between the emerald deposits in the Western Emerald Belt (WEB) and the Middle Magdalena Basin (MMB) in Colombia. The research shows that the rocks in the Furatena and Muzo formations in the WEB have a common depositional and lithofacies history with the Paja Formation in the MMB. The emerald mineralizations in the Muzo Formation in the WEB are controlled by hydrothermal and tectonic processes, with five distinct mineralizing stages. Stratigraphical correlation is proposed between the Consorcio section in this study and other sections in the WEB and MMB. The Muzo Formation in the WEB preserves lagoon facies affected by storms, suggesting a closer proximity to the coastline during the Early Cretaceous compared to the MMB.

Summary: Studies of the Paleogene lava flows in the Faroe Islands have revealed significant variations in sedimentary systems and structures within different formations, influenced by factors such as regional paleo-slope, volcanic activity, shield volcano collapses, and brittle deformation. The identification of a low-angle volcano shield in the Beinisvoro Formation has changed the previous eruption model for the extensive lava field in the region.
