- Der Lake-Murray-Meteorit, als Meteorit auch kurz Lake Murray genannt, ist mit ca. 270 kg der größte seiner Art, der je im US-Bundesstaat Oklahoma gefunden wurde, und gilt heute noch als einer der größten Meteoriten weltweit. Gleichzeitig hat er (bezogen auf das Falldatum) mit ca. 100 Millionen Jahren (oder mehr) ein extremes irdisches Alter. Dieser Meteorit wurde etwa um das Jahr 1930 (offiziell 1933, nach Graffham 1931, nach Buchwald bereits vor 1930) vom Landwirt (Farmer) J. C. Dodson am Ufer eines Bachlaufs (englisch bank of a gulley) auf dem Gebiet seiner Farm in Carter County, Oklahoma (34° 6′ N, 97° 5′ W) entdeckt, wo er offenbar vom Wasser freigespült worden war.Zur Zeit seiner Bestätigung als Meteorit galt er als der weltweit größte bekannte Brocken dieser Art.Geologisch gehört die Fundstelle zum Sandstein der , woraus auf das vorzeitliche Datum des Falls (vor ca. 90–110 Millionen Jahren) geschlossen werden kann. Der Lake-Murray-Meteorit ist zu unterscheiden vom Murray-Meteorit, einem kohligen Chondriten mit 12,6 kg Gesamtmasse, der 1950 im US-Bundesstaat Kentucky niederging. (de)
- The Lake Murray Meteorite, the largest of its kind ever found in Oklahoma and now ranked as the fifth largest in the world, was discovered on a farm in Carter County, Oklahoma in 1933. At that time it was considered the largest known specimen in the world. The farm was sold to the state of Oklahoma about the same time for the creation of Lake Murray State Park, for which the specimen was named. The largest piece is on display at the park. The meteorite was found on the site of Lake Murray State Park in 1933 by J. C. Dodson, Sr. The core was covered by a sheathing of iron oxide and shale that was about 4 inches (10 cm) thick on the exposed part and up to 6 inches (15 cm) thick on the buried part. When the specimen was removed from the ground and the sheathing removed, the core measured 30 inches (0.76 m) long, 9 inches (23 cm) thick and tapered in width from 24 inches (61 cm) at one end to 9 inches (23 cm) at the other. It weighed 600 pounds (270 kg). Allen Graffham, a geologist and curator of the park's Tucker Tower museum, was interested in a more scientific study of the object. He contacted Dr. Lincoln LaPaz of the University of New Mexico about the specimen. LaPaz confirmed that it was a meteorite. He assessed that it was composed primarily of nickel and iron, and estimated that it may have weighed 2,000 pounds (910 kg) when it struck, about 90 to 110 million years ago, but that oxidation had since worn away 5 to 6 inches (13 to 15 cm) of the surface. LaPaz, then the director of the Institute of Meteoritics at the University, carefully cut the specimen into two pieces. He performed additional tests and classed the specimen as octahedrite. He wrote that it could also be an example of a hexaoctahedrite (a transition between hexahedrite and octahedrite). A more recent reference states that the meteorite is an iron meteorite belonging to Group IIAB, which can be classified as either a hexahedrite or a coarsest octahedrite. Chemical analysis showed that the material contained 6.3% nickel (Ni), 0.5% Phosphorus (P), 53.9 parts per million (ppm) Gallium (Ga), 141 ppm Germanium (Ge), and 0.02 ppm Iridium (Ir). One half of the specimen was retained at Lake Murray, where it has been displayed at the Tucker Tower museum since the early 1950s. The New England Meteoritical Service has posted several photos taken during analysis of the specimen. (en)
- 莫瑞湖隕石，在奧克拉荷馬最大且保存良好，世界排名第五大的鐵隕石，是於1933年在美國奧克拉荷馬州的卡特郡發現的。當時有人認為是世界上最大的已知標本。農場被賣給了奧克拉荷馬州，大約在同一時間設立。標本也因此得名，最大的一塊也在公園展出。 (zh)
