“…They concluded that the craton beneath southeast India is underlain by a thick lithospheric root/ keel in excess of 200 km, suggesting an environment conducive to the stability of diamond. Regional geophysical data, involving magnetic and gravity, are integrated with the local geology to understand the structural controls in the emplacement of kimberlites in the Eastern Dharwar craton (Vani et al, 2013;Reddy, 2014). Zones of intersection of geologically confirmed lineaments are recognized to be favourable locii for the emplacement of kimberlites.…”

Major highlights of researches carried out on kimberlites, lamproites, lamprophyres, carbonatites, other alkaline rocks and mafic dykes from the Indian shield during 2012-2016 are presented. New findings involving field mapping, petrology, geochemistry (including high quality mineral based in situ isotopic studies) and geophysics have provided remarkable insights on the mode of their occurrence, timing of emplacement, mineralogy and bulk-rock composition, redox conditions, relative contribution of the lithosphere and asthenosphere, as well as their economic potential. Several large-scale geodynamic aspects such as plume-lithosphere interactions, ancient subduction events, layered structure of the sub-continental lithospheric mantle, spatial extent of the Precambrian large igneous provinces and supercontinent configurations could be unraveled from these studies on deep-mantle derived small-volume magmatic rocks.

The Bundelkhand craton is surrounded by different mobile belts. The central Indian tectonic zone (CITZ) in the southern part is one of the prominent tectonic zones. CITZ is an important structural controlling factor for the Majhgawan and Hinota Kimberlite pipes. Several dyke swarms and quartz vein fractures are resulted due to volcanic and tectonic activity in the present study area. The objective of the present study is to delineate the subsurface lineaments using different edge enhancement techniques for mineral exploration in the future. Initially, First vertical derivative (FVD), total horizontal derivative (THD), tilt derivative (TDR) and theta (THETA) map have been applied to EIGEN6C4 Bouguer anomaly data. Composite lineament density map has been generated using all enhanced maps to analyze the effect of length of lineaments in the unit area. Upward continuation maps for different height have been generated to distinguish the shallower and deeper body effects. Further, Euler 3D deconvolution technique has been applied to Bouguer anomaly data to calculate the possible depth of associated lineaments. A comparative analysis of upward continuation depth and Euler’s depth has been carried out zone wise.
