Sikhote-Alin Meteorite - a 67.5 gram Regmaglypted Specimen
Meteorite Event: February 12, 1947, 10:38 a.m. local time in the Sikhote-Alin Mountains, Maritime Province, Russia, about 270 miles northeast of Vladivostok. Latitude 46 degrees 9.6 minutes North, Longitude 134 degrees 39.2 minutes East. Hence the name Sikhote-Alin Meteorite.
- Presents a ragged, twisted surface with regmaglypts ("Thumb-print" like indentations) and a ragged, twisted surface
- Data from numerous investigations of the chemical composition of the nickel-iron, troilite, chromite, and schreibersite present in the Sikhote-Alin meteorite are presented. The greatest number of elements (about 50) are found in the nickel-iron (kamacite with traces of tenite and rabdite). The Ga, Ge, and Ni content of the Sikhote-Alin meteorite places it in the chemical group IIb.
