The Gujargaon meteorite was observed to fall on a cotton field at Gujargaon in Dewas district, Madhya Pradesh, India, on the afternoon of the 4th of September, 1982. It is an oriented stone with a saucer‐shaped front and regmaglypted rear with surfaces of more than one generation, and is entirely covered by fusion crust. Gujargaon is an H5 chondrite with rare chondrules integrated with the matrix. Intense fracturing with fractures filled by glassy veins, and undulose extinction and deformation‐twin lamellae in troilite bear evidences of shock. Compared to average H‐group chondrites Gujargaon appears to have higher contents of SiO 2 and normative pyroxene.
