Iron meteorite, Octahedrite (IIE, Of)
Fall, 29 Aug 2006; 6.8 kg

Two shepherds witnessed a daylight fall and turned the Fe-Ni mass (Ni 9.5%) over to authorities. Regmaglypts are found on the surface and the interior is dominated by kamacite accompanied by taenite. Neumann bands in kamacite and martensitic regions indicate significant preterrestrial shocks. Schreibersite is relatively abundant and unspecified silicates have been mentioned in early reports. Solar wind gases (He, Ne, Ar) have also been reported.

Kavarpura is a member of the relatively small group of IIE irons (n = 22). As one of only two witnessed IIE falls, one would expect more detailed studies to emerge in coming years. The main mass is being held at the Geological Survey of India (Calcutta).
