Physical properties

Formation & geological history

Formed in the early solar system approx. 4.5 billion years ago, likely from the core or mantle of a fragmented asteroid. Entered Earth's atmosphere at high velocity, creating a fusion crust.

Uses & applications

Scientific research, educational displays, aerospace alloy research, and high-end collector market.

Geological facts

Many meteorites are older than any rock found on Earth's surface. A neodymium magnet (visible in photo) sticking to the side is a primary indicator of high nickel-iron content common in space rocks.

Field identification & locations

Identify by high density (heavier than Earth rocks of same size), magnetic properties, and presence of a fusion crust. Found worldwide, but easiest to spot in deserts or antarctic ice fields.

Dark Igneous Rock (Likely Basalt or Diabase)

Basalt (extrusive igneous rock) or Diabase (intrusive igneous rock - also known as Dolerite), largely composed of plagioclase feldspar, pyroxene (augite), and sometimes olivine and amphibole. Exact mineralogy would require thin section analysis.
