description Lancé Overview
Lancé is a CO3 carbonaceous chondrite that fell in France in 1872. CO meteorites are characterized by abundant, generally small chondrules set within fine-grained material, and their type 3 classification indicates limited thermal equilibration compared with more metamorphosed chondrites. Lancé therefore provides researchers with comparatively primitive material for examining chondrule formation, early mineral assemblages, and the accretion history of carbonaceous asteroids.
help Lancé FAQ
What kind of meteorite is the Lancé meteorite?
Lancé is classified as a CO3 carbonaceous chondrite, a rare type of stony meteorite known for having abundant, small chondrules. The "3" in its classification means it has experienced very little thermal metamorphism, preserving its primitive early solar system materials.
When and where did the Lancé meteorite fall?
This historic meteorite fell in 1872 in France. It is one of the classic European meteorite falls that helped early scientists study the composition of carbonaceous space rocks.
Why is the Lancé meteorite scientifically important?
Lancé is highly valued by researchers because CO3 chondrites contain pristine, unaltered materials from the dawn of the solar system. Its fine-grained matrix and small chondrules offer a detailed look at the original solar nebula's dust and grains.
How does the Lancé meteorite differ from other carbonaceous chondrites?
Lancé belongs to the CO (Ornans-like) group, which generally features smaller chondrules compared to the CV (Vigarano-like) group. Its chemical makeup and limited thermal alteration make it a crucial reference point for studying carbonaceous meteorites.
