Weathered meteorite.
Meteor showers are usually named after a star or constellation that is close to where the meteors appear to originate in the sky. Perhaps the most famous are the Perseids, which peak around August 12 every year. Every Perseid meteor is a tiny piece of the comet Swift-Tuttle, which swings by the Sun every 135 years.
Typical Meteorites vesicular basalt Iron debris concretions Fresh, black fusion crust Weathered brownish fusion crust Iron-nickel meteorite (outside) Outside of old stony meteorite Iron-nickel meteorite (interior cut & etched with acid) Metal flecks & round chondrules Rare stony meteorite: no chondrules, not very magnetic. magnetite sAll of the lunar meteorites are finds, in some cases significantly weathered (Korotev, 2012). Lunar provenance is proven for these meteorites by a variety of evidence, but the single most useful constraint comes from oxygen isotopes (Clayton and Mayeda, 1996; Hallis et al., 2010). It is an iron meteorite about two meters wide. A small piece of the meteorite, called "Lebanon B", can be seen in the foreground. The angular cavities on the surface of the meteorite may have been cavities once filled with olivine crystals, or they may be where metallic crystals of vulnerable composition were preferentially weathered.

Physics of the Earth …Iron-oxide nodules or concretions are the most common kind of meteorwrong sent to us. Highly weathered meteorites may contain some hematite, magnetite, and maghemite. Do a streak test. If it is a big rock, then it is not a meteorite. too big; Most stony meteorites are smaller than people think they are. If you like statistics, see this.
SEE professional testing. There are three classes of meteorites: stony, iron, and stony-iron. A meteorite is heavier than an ordinary rock and will be attracted to a magnet. The condition of a meteorite can range from fresh to very weathered. Fresh meteorites have fusion crust, an aerodynamic shape and possibly thumbprints (regmaglypts). SEE professional testing.

The amount of nickel-iron suggests H group, and the variability of olivine and pyroxene compositions type 3, hence the meteorite is classified as an H3 chondrite (estimated H3.5).The meteorite is 3.1 by 2.6 by 0.8 inches large. It is surrounded by a gray reduction halo, in the otherwise red limestone. Oxygen was consumed when the meteorite weathered on the seafloor.

The hypothesis that the Brushy Creek feature was created by either a meteorite or comet impact, and, in fact, is the Brushy Creek Impact Crater, is the most promising hypothesis.

Since then, I have attempted to find some characteristic that might distinguish between these similar weathered, yet internally different, chondritic stones. But it wasn't until I cut one particular stony for my friend the well-known meteorite hunter, Donald O'Keeffe, that I recognized an interior pattern different from other stones from this area.
