The present study deals with classical problem of edge detection in potential field data over complex tectonic regime for both shallower and deeper sources, simultaneously. Balanced horizontal derivative (BHD) technique is a latest concept which delineates edges using balancing amplitude responses sources. BHD has been validated by comparing total (THD) technique. Initially, three different synthetic models have generated spherical, cylindrical vertical prismatic objects at depths...
The main sought of this study is to assess the landslide susceptibility map (LSM) East Sikkim Himalaya based on comparative model analysis using frequency ratio (FR), logistic regression (LR), random forest (RF) and integration analytical hierarchy process (AHP) with FR (AHP-FR). models were trained by 166 landslides (70% training) 12 causative factors whilst tested help 71 (30% testing). Their spatial correlation between was analysed a multicollinearity test. generated LSM classified into...
High-resolution satellite gravity data of recovery and climate experiment (GRACE) generated by Earth Gravity Model-2008 (EGM2008) have been utilised for geological mapping the Jharia coalfield. The GRACE EGM2008 classical processed estimation anomaly map. map has enhanced using first second Vertical Derivatives techniques. Geological structural maps study area overlapped over different derivative to analyse correlation with subsurface structures area. Major distinct signatures, on maps, are...
Mining plays a critical role in economic development, yet it presents significant safety risks and environmental challenges. Balancing worker preservation while maintaining sustainable practices is pressing concern for the modern mining industry. This study explores use of integrated geophysical techniques to enhance mine assessments support operations. By combining methods such as Electrical Resistivity Tomography (ERT), seismic surveys, Ground-Penetrating Radar (GPR), magnetic gravity...
Groundwater resources in hard-rock terrains are particularly susceptible to stress due their intricate geological formations and limited recharge capacity. This study presents a novel methodology for assessing aquifer within the Barakar River Basin of Chotanagpur Plateau, leveraging integration Soil Water Assessment Tool (SWAT) advanced deep learning models. A comprehensive evaluation was conducted using 20 hydrogeological socio-economic parameters, including precipitation, slope, land use,...
The Palaeo- to Meso-Proterozoic (1.0–2.4 Ga) North Singhbhum Mobile Belt (NSMB) is an assembly of multiphase folded, low- medium-grade meta-sedimentary and meta-igneous rocks, lying within the north crustal province. mobile belt situated between Archean craton in south Meso/Neo-Proterozoic (0.9–1.7 Chotanagpur Gneissic Complex north. Gold mineralisation moderate concentration reported from different parts NSMB along shear /fracture zones volcano-sedimentary rocks sequence. structurally...
The present study attempts a conjugate analysis of satellite-based remote sensing, gravity, and magnetic data for evaluation structures tectonic new insights on Kimberlite emplacement around the Bundelkhand Craton. Initially, Landsat Operational Land Imager (OLI) has been enhanced using high-pass filtering delineation lineaments. A combined lineament density map prepared from processed image, Bouguer RTP (Reduction to pole) data, which are further correlated with reported...
