Types of Meteorites: Stony, Iron, and Stony-Iron Explained | Buy Meteorite, LLC

Chondrite L3 Meteorite

Introduction: More Than Just Space Rocks

Meteorites are more than mysterious stones from space — they’re ancient messengers carrying secrets of the solar system’s formation. At Buy Meteorite, LLC, we believe understanding their types helps collectors appreciate their beauty, value, and scientific importance.


The Three Main Types of Meteorites

Meteorites are classified based on their chemical composition and structure. The three main types are stony, iron, and stony-iron meteorites.


🪨 1. Stony Meteorites (Chondrites and Achondrites)

These make up about 94% of all meteorite finds. Stony meteorites resemble Earth rocks but contain minerals and features not found on our planet.

🔹 Chondrites

  • The most primitive type of meteorite.

  • Contain tiny round grains called chondrules, formed over 4.5 billion years ago.

  • Never melted since their formation.

  • Examples: NWA 869, NWA 14870 (CR2).

🔹 Achondrites

  • Don’t contain chondrules.

  • Come from larger planetary bodies that underwent melting and volcanic activity.

  • Rare and often come from asteroids, the Moon, or Mars.

  • Examples: NWA 7831 (Diogenite), Lunar or Martian meteorites.


🪙 2. Iron Meteorites

Composed primarily of iron and nickel, these meteorites are believed to originate from the core of ancient asteroids. They are extremely dense and display unique patterns when cut and etched.

🔸 Key Features:

  • Distinctive Widmanstätten patterns.

  • Often very heavy for their size.

  • Popular among collectors for their metallic beauty.

  • Example: Campo del Cielo, Gibeon.


🪨🪙 3. Stony-Iron Meteorites

A rare and visually striking class, stony-iron meteorites are an equal mix of metal and silicate minerals.

🔸 Two Main Subtypes:

  • Pallasites – contain beautiful greenish olivine crystals suspended in iron-nickel metal. They’re believed to form at the core-mantle boundary of large asteroids.

    • Example: NWA 15971 Pallasite.

  • Mesosiderites – brecciated rocks made from both metallic and silicate material.

Stony-irons are highly sought after for their rarity and aesthetic appeal.


How to Identify Meteorite Types

Most collectors rely on:

  • Visual inspection (texture, color, metal content)

  • Magnet test (many meteorites are magnetic)

  • Slice analysis (patterns and minerals revealed inside)

For authenticity, always buy from reputable sources like Buy Meteorite, LLC, where each specimen is classified and documented by expert labs.


Why Knowing the Type Matters

Understanding meteorite classification helps you:

  • Know the scientific origin of your specimen.

  • Assess its rarity and value.

  • Choose the right meteorites for your collection or gift.
