Magnetic Spherules with Metallic Shine in the Recent Alluvium of Rajasthan

Magnetic spherules with metallic shine ranging from a fraction of millimeter to one millimeter in size have been discovered from red coloured ferruginous soils of Quaternary period at a large number of places in western Rajasthan. Occurrence of these magnetic spherules at far away places. In the red coloured ferruginous sandy loam that overlies the Mesoproterozoic metasediments of Delhi Supergroup, the Neoproterozoic rocks of Malani Igneous Suite and sediments of Marwar Supergroup, is quite significant, especially, in view of the inferred association of magnetic spherules with the intense volcanic activity, melting of inter planetary dust, ablation of meteorites and impact of extra terrestrial bodies like the one that possibly hit the earth and caused the mass extinction at K-T boundary.
