#Observed falls

Meteorites that people saw fall, picked up soon after landing.

Famous meteorites (4)

  • ChassignySeen to fall in France in 1815, this olivine-rich stone was the first known Martian meteorite to be witnessed falling.
  • JilinIn 1976 a meteorite shower over north-east China included a single stone of about 1,770 kilograms – the largest stony meteorite ever seen to
  • Wold CottageEngland's largest single meteorite landed beside a Yorkshire ploughman in 1795 – and helped prove that stones fall from the sky.
  • ZagamiA piece of Martian lava that landed close to a Nigerian farmer in 1962 – the largest single Martian stone ever seen to fall.

Meteorite types (23)

  • AubritesPale, almost iron-free rocks made of enstatite, from an extremely oxygen-poor world.
  • BrachinitesOlivine-rich rocks from an asteroid whose melt drained away. Named after Brachina in South Australia, brachinites are made mostly of iron-ri
  • CH chondrites'High metal' carbonaceous chondrites with tiny chondrules. CH chondrites are rich in iron-nickel metal, about 20% of the rock by vol
  • CM chondritesWater-rich carbonaceous chondrites full of organic molecules, Murchison and Winchcombe among them.
  • CO chondritesSmall-chondrule carbonaceous chondrites, close relatives of the CMs. CO chondrites, named after Ornans in France, have very small chondrules
  • DiogenitesPyroxene-rich rocks from deep inside Vesta. Diogenites are coarse-grained rocks made mostly of orthopyroxene, sometimes with olivine.
  • EL chondritesLow-iron enstatite chondrites. EL chondrites have less metal than EH chondrites and contain alabandite, a manganese sulphide, instead of nin
  • EucritesVolcanic basalt from the crust of Vesta. Eucrites are basalts and gabbros from Vesta's crust, made mainly of pigeonite (a calcium-poor p
  • H chondritesHigh-iron ordinary chondrites: about a third of all meteorites seen to fall. H chondrites have the highest total iron of the ordinary chondr
  • HowarditesBroken rubble from the surface of asteroid Vesta, mixing crust and mantle rocks. Howardites are regolith breccias: rocks made from the broke
  • IIE ironsIrons full of silicate fragments, possibly from asteroid Hebe. IIE irons are octahedrites of varying coarseness that often contain silicate
  • L chondritesLow-iron ordinary chondrites: the single most common group of meteorites. L chondrites have less metal than H chondrites, typically 4% to 10
  • LL chondritesLow iron, low metal: the ordinary chondrites matched to asteroid Itokawa. LL chondrites have the least metal of the ordinary chondrites, onl
  • LodranitesCoarse-grained leftovers after melt drained away. Named after Lodran in Pakistan, which fell in 1868, lodranites are coarser-grained than ac
  • MesosideritesJumbled breccias of metal and basalt, made in a violent collision. Mesosiderites are breccias of roughly equal parts iron-nickel metal and s
  • Ordinary chondritesThe everyday meteorite: four in every five falls. Three groups, H, L and LL, from at least three asteroids.
  • PallasitesGem-like olivine crystals set in iron-nickel metal. Pallasites contain large olive-green crystals of olivine embedded in iron-nickel metal.
  • R chondrites (rumurutiites)Highly oxidised chondrites with almost no metal. R chondrites are named after Rumuruti in Kenya, the only one seen to fall (1934).
  • ShergottitesThe most common Martian meteorites: young basaltic and olivine-rich rocks. Shergottites, named after Shergotty in India (fell 1865), make up
  • Stony-iron meteoritesRoughly equal parts metal and silicate. Rare, and among the most beautiful meteorites.
  • Stony meteoritesMeteorites made mostly of silicate minerals. They are by far the most common kind seen to fall.
  • UreilitesCarbon-rich rocks with diamonds, from an asteroid shattered by a giant impact. One was tracked in space before it hit Earth.
  • WinonaitesPrimitive achondrites related to the silicate inclusions in IAB irons. Named after the Winona meteorite, found buried in a Sinagua ruin in A
