“…Lakes and artesian wells are widely distributed in the Gobi Desert (GD) on the Mongolian Plateau, and some rivers, perhaps surprisingly, originate from deserts. , The increased upwelling discharge of groundwater in the Taklimakan Desert formed new lakes with an area of 300 km 2 in 2003 . Despite abundant groundwater resources, exploring and exploiting new sources of groundwater in arid regions requires considerable effort. , One of the most challenging reasons for this continued difficulty is the unclear recharge of the groundwater in deserts, which is usually regarded as “fossil” water or a limited recharge of local precipitation. ,, …”

Deserts are distributed in arid areas, and groundwater is the primary source of drinking water and agricultural irrigation for the residents. However, owing to an insufficient understanding of desert groundwater sources, water management policies in arid areas often fail to meet actual water demands. The Badain Jaran Desert is a typical desert with abundant groundwater. However, local economic development has been severely limited due to water resource shortages. To address this challenge, in this study, an integrated approach was utilized to perform a groundwater exploration of the study area. Evidence from δ 2 H and δ 18 O and tracer logging tests in different interdune basins suggests that the desert's groundwater originates from the Qilian Mountains through rapid cross-basin flow and then upwells from hidden volcanic craters in the desert. The deep channels likely comprise contraction joints formed by cooling of the overlying rocks during magmatic diagenesis. Several deserts worldwide receive external recharge from plateaus or mountains rather than from "fossil" water. The initial characteristics of low 87 Sr/ 86 Sr values, which were less than 0.7065, changed with the retention time of groundwater in the aquifer. We conclude that desert groundwater resources have abundant recharge and can meet water demands under a reasonable development approach.

“…Whatever the climatic circumstances, the prevalence of quartz in the bedrock makes it exceedingly unlikely that the suite of clay minerals present in the soil is the result of weathering [19]. The parent material of CaCO 3 -rich soil in the northwestern coastal region of Egypt is composed of a variety of rocks, e.g., limestone, sandstone, CaCO 3 -rich shale, or marl, formed as a result of weathering, translocation, and deposition processes under the arid climatic conditions [20,21]. The following parameters were used to choose the marine soil profiles: CaCO 3 , soil texture, electrical conductivity (EC), and hydrogen power; macronutrients such as nitrogen, phosphorus, potassium, and organic carbon; micronutrients such as manganese, zinc, iron, and copper; and other sodium and CEC [20].…”

Despite studies focusing on soil substrates (carbon and nitrogen) and heavy metal availability, the impact of diversified parent materials in arid alkaline regions has received little attention. To reveal the influence of parent material, we investigated four different parent materials: fluvio-marine, Nile alluvial, lacustrine, and aeolian deposits. We assessed the effect of soil parent materials through selected soil physical and chemical properties, such as clay content, bulk density, pH, and available phosphorus (AP). The Tukey HSD test (SPSS ver. 23) was used to assess the soils derived from these different sediments. Using the R “glmulti” package, we examined this effect in a model of mixed-effects meta-regression. The sum of Akaike weights for models that contained each element was used to estimate the importance of each factor. The average contents of soil organic carbon (SOC) and total N in alluvial deposits were greater (p < 0.001) than those of marine, aeolian, and lacustrine deposits. A multivariate analysis in arid regions revealed that parent material, soil pH, and the availability of P had the greatest effects on SOC concentration, whereas clay content, available P, soil pH, parent material, and bulk density had the greatest effects on soil total nitrogen. The average content of Fe in the aeolian deposits was greater (p < 0.001) than those of marine, alluvial, and lacustrine deposits, without any significant differences between the latter two deposits. We found that the highest average contents of zinc (Zn), manganese (Mn), and copper (Cu) were recorded in alluvial deposits, with significant differences between other deposits. Soil parent material was the major factor impacting soil iron (Fe) content, along with clay content and soil pH. However, soil bulk density was the most important factor controlling soil Zn and Mn contents, while SOC drove Cu content. This study will help in developing a more accurate model of the dynamics of soil substrates and availability of heavy metals by considering readily available variables, such as parent materials, soil pH, soil bulk density, and clay content.

“…The third question is about mapping the structural lineaments (Ganguli and Pal; Sun et al) which is used widely in geological mapping (Altinoğlu, 2023;Ashraf and Filina, 2023;Bayou et al, 2023;Ibrahim et al, 2023;Lghoul et al, 2023;Mnasri et al, 2023;Qadir et al, 2023). Such applications are based on the qualitative interpretation of gravity anomalies in which the edge detection filters are usually applied to enhance the lineament.…”

Editorial on the Research Topic Applications of gravity anomalies in geophysicsWith the progress of cheap, lightweight, and efficient gravimeters (Carbone et al., 2020;Stray et al., 2022;Kim and Choi, 2023), gravity anomalies are expected to receive wider attention in the future, opening up new perspectives for increasing the capability of gravimetry to Earth sciences. Since the knowledge of the crustal density of a planet is important in determining its interior structure, gravity anomaly is widely used in Solid Earth and exploration geophysics, and also extended to the moon and Mars. In addition to the routine applications focusing on the crustal density structure, contributing to the characterization and definition of underground structures at various scales, time-varying gravity, microgravity survey, and gravity admittance are widely applied in order to supply unique information on the dynamics of underground processes. The goal of this Research Topic is to highlight the various extracted information from gravity anomalies in applications, toward an understanding of choosing appropriate methods dealing with gravity anomalies in varying study cases.There are ten accepted papers on this Research Topic focusing on the following four research questions.The first question is about the equivalent-layer technique (Oliveira Junior et al.) which present a comprehensive review of the computation aspects concerning the equivalent-layer technique. The equivalent-layer technique is used widely in processing gravity and magnetic anomalies, e.g., the downward continuation and the reduction to the pole at low latitudes. While such method is very inefficient for dealing with massive data sets, lots of computationally efficient methods have been proposed to reduce its computational cost. The authors from Observatório Nacional and Universidade do Estado do Rio de Janeiro (Brazil) present a comprehensive review of diverse strategies to solve the linear system of the equivalent layer in which the advantages and disadvantages for the existing strategies are described in detail.The second question is about the time-varying gravity (Zhu et al.) which is used in monitoring the subsurface mass variation. Zhu et al., from China Earthquake Administration, have conducted numerous applications focusing on the time-varying gravity in earthquake research in the Chinese Mainland. The gravity changes before
