Summary: Geophysical data and remote sensing data were used to evaluate the groundwater-bearing potential zones in Wadi Fatimah, western Saudi Arabia. The study found that the area has a high potential for groundwater storage, with high slopes and highlands allowing rainwater to infiltrate and recharge the groundwater. The results also identified an unconfined aquifer with low resistivity and a depth of up to 50m below the ground surface, making it a promising area for future groundwater supply.

Summary: The development of Tabuk Basin in Saudi Arabia is crucial for increasing freshwater resources and improving aquifer recharge potential due to its arid conditions, limited aquifers, high groundwater salinity, and rapid population, industrial, and agricultural growth. This study used statistical analysis, remote sensing, and GIS to determine water priority in the eighteen sub-basins of the Tabuk Basin. The findings identified the sub-basins with the highest priority for soil erosion mitigation and highlighted promising sites for building new wells to reduce surface runoff and soil erosion through aquifer infiltration and abstraction.

Summary: Research on impact craters on Earth's surface has increased globally, with investigation methods such as remote sensing, geological studies, boreholes, geophysical surveys, and laboratory measurements being used to build dynamic models of crater formation. This study focused on investigating near-crater sediments at the Wabar crater field in Saudi Arabia using magnetic, transient electromagnetic, seismic, and ground-penetrating radar methods to explore meteorite remnants, meteoroid direction, and deformational structures associated with meteorite impacts. The geophysical findings suggested that the meteorite direction was from north to south, with no evidence of major meteorite pieces found at the site.

Summary: The present study aimed to investigate the groundwater chemistry and its impact on human health in the Harrat Khyber region of Western Saudi Arabia. The results showed that the groundwater chemistry was influenced by ion-exchange and evaporation processes, and there was a wide variation in the concentration of major ions. Additionally, heavy metals such as arsenic, chromium, copper, nickel, selenium, and zinc were found to be mainly of geogenic origin, causing minimal contamination in the groundwater. However, excessive levels of nitrate were observed, making the water unsafe for human consumption.

Summary: The study investigated the nitrate contamination and nitrogen cycling in the Babu karst aquifer in Guizhou Province, Southwest China using multiple stable isotopes and models. The results showed that nitrogen fertilizer, manure and sewage, and soil organic nitrogen were the main sources of nitrate in winter, and nitrification was the primary nitrogen transformation process. Denitrification could also occur locally, contributing to nitrate enrichment.

Summary: Grain-size analysis was conducted on fourteen sandstone samples from the Wasia Formation to determine hydrodynamic conditions and depositional environments. The results showed that the lower section is coarse to medium-grained with poor sorting, while the upper section is medium to medium-well-sorted fine-grained. The sediments have a unimodal distribution in the lower section and a bimodal distribution in two beds. The LDF method indicated aeolian, marine, and fluvial environments as the predominant depositional environments.

Summary: This study examines the potential for thermogenic gas generation from the Al Renk shales in the Melut Basin, South Sudan, using organic geochemical and basin modelling results. The research shows that the Al Renk shales are good gas-source rocks with high total organic carbon content. However, the study also highlights the contrast between the source of organic matter and the depositional environment. High thermal maturation is crucial in altering the original organic matter and decreasing hydrogen index values. The findings suggest the need for conventional gas exploration in deeper stratigraphic successions in the Melut Basin.

Summary: The global increase in greenhouse gas (GHG) emissions has led to a demand for low-cost and long-lasting technologies to reduce GHG production and enhance soil carbon storage. Biochar can be used to sequester carbon in a stable form, but its effectiveness in mitigating GHG emissions is still debated. This study synthesized information on the ability of biochar to mitigate CO2, N2O, and CH4 emissions and found that factors such as feedstock type, pyrolysis temperature, and application rate significantly influenced its effectiveness. Overall, biochar shows promise as a tool to reduce GHG emissions, but further research is needed to better understand its functionality and optimize its use.

Summary: This study examines the organic matter in the dark shale samples of the Silurian Qusaiba Formation from Saudi Arabia. The samples indicate a marine environment with varying oxygen levels. Biomarkers suggest that the organic matter primarily comes from marine organisms and was deposited in conditions of low oxygen. Inorganic geochemical indicators point to a warm-humid climate and low salinity stratification conditions for the water columns in which the Qusaiba shales accumulated.

Summary: This study focuses on the late stage of the Arabian Shield evolution and reveals the presence of post-collisional magmatism in the central and northern parts of the Arabian Shield. The studied granites are mainly composed of alkali feldspar granite and syenogranite, showing enrichment in light rare earth elements and depletion in heavy rare earth elements. They likely represent good sources of geothermal heat, uranium-thorium, and rare earth element mineralization.

Summary: This study examines the geochemical and petrological characteristics of carbonate-rich sediments from the Upper Cretaceous Shu'ayb Formation in northern Jordan. The organic matter characteristics and geological temperatures for oil generation are analyzed. The results suggest the presence of high TOC and hydrogen index, indicating Types I-II kerogens. The organic facies are sulfur-rich and exhibit the potential for producing paraffinic oil with low wax content. The distribution of activation energy and vitrinite reflectance values further support the Type II-S kerogen organic facies. This research provides insights into the organic-rich carbonate's potential for generating sulfur-rich oils.

Summary: This study analyzed the geochemical characteristics of oil stains from the Cretaceous Harshiyat Formation in eastern Yemen, indicating a mixed organic matter input from a mature source rock. Biomarkers suggested the presence of marine and terrestrial organic matter in the source rock, with indicators correlating well with shales in the Late Cretaceous Harshiyat Formation. The analyzed oil stains likely originated from a mature source rock and migrated into sandstone and limestone reservoirs in the North Hadramaut High area through normal faults.
