Karimati        25°54’N, 80°10’31"E

Uttar Pradesh, India

Confirmed fall: 28 May 2009

Classification: Ordinary chondrite (L5)

History: Around noon on 28 May 2009, an eyewitness in the village of Karimati heard a roaring sound and a blackish stone fell near a wall in his house, 1.5 m away from him. The fall created an 18 × 15 cm oval-shaped pit in the ground. Out of fear, villagers put the stone in a water tank for about 72 hrs. When the local authorities came to know about it, they took the material in their possession. Dr. H.C. Verma (IIT) visited the place on June 2, following a newspaper report and took possession of the sample. Dr. Verma sent the meteorite to PRL, and it was then transferred to GSI.

Physical characteristics: The stone is covered with a black crust, except on one face, where a piece has been broken off by the villagers. The sample has rounded to sub-rounded edges. Regmaglypts are also observed. A few chondrules are visible by naked eye.

Petrography: The meteorite is composed of olivine + orthopyroxene + feldspathic glass (plagioclase composition) + Fe-Ni metals (kamacite and taenite)+ troilite ± apatite ± merrillite. Clinopyroxene is rare. The chondrules are composed of olivine and orthopyroxene, whereas the interstitial spaces (mesostasis) are occupied by feldspathic glass. Chondrule range up to 1000 μm in diameter. The shape of chondrules varies from near circular to elliptical to sub-elliptical. Barred olivine (BO), granular pyroxene (GP), porphyritic olivine (PO), porphyritic olivine pyroxene (POP) and granular olivine (GO) chondrules are present. Matrix is relatively fine grained and thoroughly recrystallized in which a feldspathic melt mosaic is disseminated. The feldspathic melt (plagioclase composition) is fine grained (<50 μm), patchy and interconnected in the matrix. At places it forms melt veins. The matrix is also brecciated. Troilite forms rim around kamacite grains.

Classification: Ordinary chondrite (L5)

Specimens: Main mass at GSI.
