description Renazzo Overview
Renazzo is a carbonaceous chondrite meteorite that fell near Renazzo, Italy, in 1824. It is the type specimen of the CR, or Renazzo-type, group of carbonaceous chondrites, which are noted for abundant chondrules, metal, and chemically primitive material. Researchers study such meteorites because they preserve components formed during the early history of the solar system and record limited parent-body alteration.
insights Ranking position
Renazzo ranks #31 of 213 in the Meteorite ranking, behind Esquel, ahead of Lafayette.
help Renazzo FAQ
Why does the CR meteorite group take its name from Renazzo?
Renazzo is the type specimen used to define the CR, or Renazzo-type, carbonaceous chondrites. Its chemistry and texture provide the reference against which other proposed CR meteorites are classified.
What are the large round objects visible inside Renazzo?
They are chondrules, once-molten droplets that cooled before becoming part of the meteorite's parent asteroid. CR chondrites are known for relatively large chondrules, abundant metal, and fine-grained matrix.
What happened during the Renazzo meteorite fall?
The meteorite fell near Renazzo, Italy, in January 1824 after a bright light and explosive sounds were reported. It broke into three main pieces plus smaller fragments scattered over nearby fields.
Why do scientists call Renazzo primitive?
Its components preserve material formed during the Solar System's earliest history rather than rock melted and remade inside a planet. Renazzo is classified as CR2, indicating a carbonaceous chondrite that experienced substantial low-temperature alteration but limited thermal metamorphism.
