description Vigarano Overview
Vigarano is a CV3 carbonaceous chondrite meteorite that fell near Vigarano Mainarda, Italy, in 1910. It gives its name to the CV, or Vigarano-type, group and contains chondrules, metal, and abundant calcium-aluminum-rich inclusions. These refractory inclusions are among the oldest dated solids formed in the solar system, making Vigarano relevant to research on its earliest materials and conditions.

Vigarano ranks #33 of 213 in the Meteorite ranking, behind Renazzo, ahead of Fukang.
help Vigarano FAQ
Why is the Vigarano meteorite important to meteorite classification?
Vigarano is the type specimen that gives the CV carbonaceous chondrite group its name. The letter V in CV refers to Vigarano, while the 3 indicates relatively low alteration of its primitive components.
When and where did the Vigarano meteorite fall?
Vigarano fell near Vigarano Mainarda in Italy's Ferrara province on January 22, 1910. It was a witnessed fall rather than a meteorite discovered long after landing.
What are the pale inclusions visible inside Vigarano?
Many are calcium-aluminum-rich inclusions, usually abbreviated CAIs. These refractory objects formed very early in the solar system and are among the oldest dated solid materials studied by planetary scientists.
How does Vigarano differ from an ordinary chondrite?
Vigarano is a carbonaceous CV3 chondrite containing primitive chondrules and abundant refractory inclusions. Ordinary chondrites such as H5 meteorites contain different proportions of metal, silicates, and volatile-rich material.
