We present here a singular spectrum analysis (SSA)-based low pass filtering algorithm for regional and residual gravity anomaly separation. The data adaptive decomposition in SSA frequency facilitates reduction of the artefacts non-linear non-stationary data. Initially, method was tested on synthetic representing combined response components derived from geological structures like infinite horizontal layers, intrusive dykes, deep-seated faults volcanic bodies compared with fast Fourier...
A government airborne geophysical survey flown in the late 1970s detected a large Magnetic anomaly at Gadarwara, Madhya Pradesh, north-central India. Deep drilling indicates that oval-shaped is caused by underlying Magnetite-bearing banded iron formation belonging to Mahakoshal Formation of Archean Early Proterozoic age. The hosted tectonic rift zone (Narmada-Son Lineament). After alluvium up 312 m thick, rocks intersected depths 612 provided core samples for research. Broadly speaking,...
The Deccan basalt province controls the hydrologic regime of an area ∼500,000 km2 in central India. These basalts are largely layered flows with massive, vesicular and amygdaloidal varieties. We have studied sequence Ghatia micro-watershed Madhya Pradesh, India, using multichannel analysis surface waves at several sites. shear wave velocity sections reveal nature a cap low weathered zones. In some sections, weathering zones undulating. Interestingly, massive flows, there low-velocity...
Abstract Summary Application of Geophysical Methods (Gravity and Magnetics) to Chromite Prospecting: An example from Kathpal Area, Sukinda, Orissa.
Summary In the Indian scenario, use of geophysical surveys in mineral exploration was still infancy stages. However, there is a decrease success, despite increased company expenditure on surveys. As mines are going deep with ore grade, need to multidisciplinary within mining districts (brownfields) as discoveries green fields be carried out meet future demand. One main objectives acquire and collate high-resolution geological, petrophysical measurements. This article provides preview data...
