description Juvinas Overview
Juvinas is a basaltic eucrite meteorite that fell in Ardèche, France, in 1821. Eucrites are achondrites derived from basaltic igneous rocks, and they form part of the HED clan together with howardites and diogenites. Juvinas is an early and substantial studied fall whose mineralogy and texture provide evidence of melting, crystallization, and later impact processing on a differentiated parent body widely identified with asteroid 4 Vesta.
help Juvinas FAQ
What type of meteorite is Juvinas?
Juvinas is a eucrite, a basalt-rich achondrite belonging to the HED meteorite clan. Unlike ordinary chondrites, it comes from material that melted, differentiated, and formed igneous rock on a parent body.
Is Juvinas thought to come from asteroid Vesta?
Eucrites, howardites, and diogenites are widely linked to asteroid 4 Vesta through their mineralogy and spectral similarities. Juvinas is therefore commonly studied as a sample of crustal material from the Vesta-related parent body.
When and where did the Juvinas meteorite fall?
It fell in Ardèche, France, in 1821. Because the fall was observed and material was recovered soon afterward, Juvinas became an important early reference specimen for eucrite research.
Why does Juvinas look more like volcanic rock than a typical meteorite?
Its parent material was basalt produced by melting and volcanic or intrusive processes on a differentiated asteroid. The rock is dominated by minerals such as pyroxene and plagioclase rather than the chondrules seen in primitive chondrites.
