“…Fault zones, folds, and other structural features can cause variations in the density of the rocks, leading to gravity anomalies. By analyzing the gravity data, geophysicists can infer the presence of these structures and map their orientations, extents, and relationships [95] . Gravity surveys provide valuable information about the structural framework and deformation history of the basement rocks.…”

“…By combining multiple datasets, geologists can refine interpretations, identify correlations between different data types, and create more detailed and reliable basement rock maps. Gravity surveys contribute significantly to basement rock mapping by detecting gravity anomalies, delineating geological structures, mapping basement contacts, identifying subsurface features, targeting mineral exploration, and integrating with other data sources [95] . These surveys provide valuable information about the density variations and gravitational field, helping geologists understand the subsurface geology, structural framework, and potential mineralization associated with basement rocks.…”

Lithological mapping in semi-arid regions has witnessed a phase of transformation due to advancement in remote sensing technology. This has permitted a more comprehensive understanding of surface lithological units. This review explores the evolution of remote sensing mapping techniques and their diverse uses at semi-arid regions, underscoring the significance of the mapping procedure and the prospects. Remote sensing technology has been advancing with moderate to high resolution spaceborne and airborne sensors, unmanned aerial vehicle (UAV) technology and LiDAR (light detection and ranging). These have significantly enhanced capacity, accuracy and the scope of lithological mapping procedures. Especially, the advancement of machine learning and Artificial Intelligent (AI) in automated remote sensing data analysis has ignited more precise ways of identifying and classification of lithological units. Using hybrid remote sensing/machine learning mapping techniques has extended the horizon of geological studies where mineral exploration, water resource management, land use planning, environmental assessments, and risk mitigation are particularly considered. The maps derived provide deeper insights into accurate delineation of mineral deposits, identification of potential sources of water, and aiding those making informed decision making for land development and resource management. The importance of hybrid remote sensing/ machine learning techniques lies with the profound contributions made through geological history, resource exploration, environmental preservation, and risk management directed to fragile ecosystems such as semi-arid environments. The future of the hybrid methodologies holds promise for further advancements in integrating various data sources, exploitation of their contextual properties, refining AI algorithms for faster and more accurate analysis, and methodologies that are specific to environments. These evolving technologies and diverse applications present a trajectory targeted at more comprehensive utilization of geological resources and improvement of environmental stewardship even to fragile regions.

“…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
