description Havero Overview
Havero is a ureilite meteorite that fell in Finland in 1971 and was recovered as a single stone weighing approximately three kilograms. Ureilites are primitive achondrites composed chiefly of olivine and pyroxene, commonly accompanied by carbon in forms that can include graphite and microscopic diamond. Because witnessed ureilite falls are uncommon, Havero provides unusually well-documented material for studying this carbon-rich meteorite group.
help Havero FAQ
What type of meteorite is Havero?
Havero is a ureilite, a rare class of primitive achondrite composed primarily of olivine and pyroxene with significant carbon content. Ureilites are unusual because they retain primitive chemical signatures despite having undergone partial melting.
When and where did Havero fall?
Havero fell in Finland in 1971 and was recovered as a single stone weighing approximately three kilograms. It is one of the relatively few meteorites recorded as falling in Finland.
Do ureilites like Havero contain diamonds?
Some ureilites do contain tiny diamonds or lonsdaleite formed by shock processes during impacts on their parent body. The carbon in ureilites is commonly present as graphite, and the specific carbon phases can vary between specimens, though the presence of carbon in some diamond form is a known feature of the ureilite class.
How rare are ureilites compared to other meteorite types?
Ureilites are relatively uncommon, representing only a small fraction of known meteorite falls worldwide. Their unusual combination of primitive and igneous characteristics makes well-documented specimens like Havero scientifically valuable for understanding early solar system processes.
