Common Meteorite Characteristics in the Field
When you’re examining a potential meteorite in the field, you’ll want to focus on three key physical indicators: the distinctive fusion crust with flow lines, the presence of regmaglypts (thumbprint-like depressions), and the unusually heavy weight relative to size. You can quickly test the specimen’s magnetic properties using a strong neodymium magnet, as most meteorites contain sufficient iron-nickel content to exhibit magnetic attraction. The specimen’s color and surface characteristics provide essential diagnostic information, particularly the presence of a dark, often black fusion crust that may show signs of weathering to reddish-brown over time. Understanding geological factors, such as rock layers and ore density, is crucial when identifying meteorites in the field.
Physical Features and Texture
Meteorites possess distinct physical features that set them apart from terrestrial rocks in the field. You’ll notice their distinctive dark gray to black fusion crust, formed during atmospheric entry, and their surface texture can be either shiny or velvety with unique flow lines.
When you’re examining a potential meteorite, you’ll find it’s heavier than Earth rocks of similar size due to its high metal content.
The texture reveals key identifying characteristics. You’ll observe that meteorites aren’t porous like many Earth rocks but rather solid throughout.
If you’re looking at a stony meteorite, you might spot small, rounded chondrules on broken surfaces. The presence of metallic flecks, particularly on cut or polished surfaces, along with minerals like olivine and pyroxene, contributes to their remarkably dense composition.
Magnetism Testing Methods
Beyond physical appearance, magnetic properties serve as a key identifier for meteorites in the field.
You’ll find that most meteorites contain iron and nickel, making magnetic susceptibility testing a vital field testing method.

In addition to magnetic testing, using maps to plan searches in areas with historical significance can aid in the discovery of meteorites.
For effective field testing of potential meteorites, follow these essential steps:
- Use a magnetic susceptibility meter for non-destructive, precise measurements
- Keep magnets at a slight distance to prevent field erasure
- Test multiple points on the specimen for consistent readings
- Compare results with known meteorite values for your specimen’s suspected class
Consider combining magnetic testing with other identification methods for more accurate results, as some terrestrial rocks can also exhibit magnetic properties.
Color and Crust Analysis
Through careful observation of color and crust characteristics, you’ll discover key visual markers that distinguish meteorites from Earth rocks in the field.
Fresh meteorites typically display a dark gray to black fusion crust with a shiny or velvety texture, while weathered specimens often show color variability, transforming to rusty brown due to iron oxidation.
Look for distinctive flow patterns and irregular pits on the surface, which form during atmospheric entry.
Pay attention to crust durability, as the fusion crust can wear away over time when exposed to environmental conditions.
You can confirm your find by performing a streak test on unglazed ceramic – meteorites leave a characteristic brown streak.
The presence of rust spots combined with these visual indicators strengthens your identification of a potential meteorite.
