Summary: In one part of this project work, a hybrid approach has been developed to enhance the performance of Bi-dimensional Empirical Mode Decomposition (BEMD) in regional-residual separation of gravity anomaly by jointly employing low pass filter and BEMD in MATLAB. The efficacy of this hybrid approach was demonstrated using noisy synthetic and field data (Mandal and Niyogi, 2018). Another significant outcome of this work is the demonstration of effective reconstruction of broad and smooth impedance profile from first principles and even from acquired seismic reflection data. Here, we have logically extended the earlier work of Ghosh and Mandal (2016) and proposed an approach and demonstrated its success in field data (Mandal and Ghosh, 2020).
Integrated geophysical study for delineating detail subsurface structures and possible mineral deposits around Madawara region, Lalitpur, U. P., India
Summary: Integrated gravity–magnetic study over Madawara Igneous Complex (MIC) in southern part of Bundelkhand Craton helped to decipher shallow crustal configuration and mineralized zones, thereby to improve the understanding of tectonic evolution of the region. Analyses of acquired gravity and magnetic data sets and 2D inverse modeling of residual gravity anomaly have deciphered the basement configuration and subsurface continuity of mafic-ultramafic intrusive bodies thereupon providing important clues on magmatic evolution. Correlation with previous geo-chemical results (i.e., high concentration of Cr-Ni-PGE) and high gravity-magnetic anomaly over exposed mafic-ultramafic rocks helped to delineate new prospective zones in MIC (Mandal et al., 2020).
