Meaning and Definition
A small, rounded granule of silicate minerals found in some stony meteorites, representing solidified molten droplets from the early solar nebula.
A primordial building block of the solar system, often used as a window into the conditions and processes (e.g., melting, rapid cooling) present in the protoplanetary disk before planet formation.
Dialectal Variation

FAQ
Frequently Asked Questions
Yes, by definition. They are diagnostic components of chondritic meteorites. While similar processes might occur elsewhere, the term specifically refers to these meteoritic objects.
Most chondrules range from about 0.1 to 1 millimetre in diameter, roughly the size of a grain of sand or a pinhead.
They indicate that the parent body of the meteorite never underwent large-scale melting and differentiation, preserving primordial material from the solar nebula. Their textures and compositions record transient high-temperature events in the early solar system.
Sometimes. In some meteorites, like the NWA 869 chondrite, they are clearly visible as small, light-coloured specks on a broken surface. Usually, a hand lens or microscope is needed to see their details.
