LAP 02205 is a complete stone with bits of fusion crust chipped off. LAP is a basalt.Basalts are rich in iron, which causes the fusion crust to be dark. It's the terrestrial mineral that is most often mistaken for a meteorite in the field. Two lunar meteorites found in Antarctica, LaPaz Icefield (LAP) 02205 (1226 g, two views) and Queen Alexandra Range (QUE) 93069 (23 g). Be careful, as hematite (a common terrestrial iron oxide) is black, heavy for its size, and may also stick to a magnet. But most meteorite hunters use their "meteorite cane" - a magnet glued to the bottom of a long pole or walking stick - more as a tool to pick up potential meteorites than to definitively test a specimen. A chondrite's high nickel-iron content makes it adhere to a strong magnet. In modern usage the term is broadly applied to similar objects that land on the surface of other comparatively large bodies. For this reason, meteorite hunters often use metal detectors in areas where meteorites are likely to be found. meteorite, any fairly small natural object from interplanetary spacei.e., a meteoroidthat survives its passage through Earth’s atmosphere and lands on the surface. Nickel Iron: Most chondrites contain tiny flecks of nickel iron sprinkled throughout. Over time, they can literally cause a meteorite to crumble into pieces. Hematite is a common iron oxide mineral found throughout the Upstate. Finally, iron meteorites are strongly magnetic and slag is not. Heavy iron meteorites are frequently solid, dark-grey in color. All this expanding and contracting can causes stress fractures to appear on a meteorite's exterior within just a few years. Slag (middle photo) is much lighter per unit volume than iron meteorites, and is frequently multicolored (blue, red and purple iridescence). In summer, moisture that has worked its way into a meteorite will cause it to contract, and in winter, when frozen, it will expand. But that's not the case on Earth, where a meteorite will begin to age as soon as it hits the ground. Stress Fractures: A meteorite can exist in outer space for millions of years without experiencing corrosion. Note the dark brown fusion crust and the weathered, lighter colored interior. ![]() This is a typical, weathered Ordinary Chondrite. This guide provides simple at home tests that can help the reader to make. A freshly fallen Oum Dreyga (Amgala) H3-5 Chondrite showing a light colored matrix filled with iron-nickel flecks. This article teaches people the basic characteristics of how to identify a meteorite. Note the black fusion crust and light interior. So, I got the idea to put all that and more together in a short book with lots of pictures of equipment, tools, and specimens. Some metallic meteorites contain troilite, an iron. Photo of a freshly fallen Oum Dreyga Chondrite. This meteorite has been cut and polished to reveal nickel-iron flecks. The Widmanstatten pattern makes iron meteorites easy to identify when the meteorite is polished and etched.
