help Bununu FAQ

What type of meteorite is Bununu?

Bununu is a howardite, a stony meteorite made from mixed fragments of volcanic rocks. Its breccia contains eucrite and diogenite clasts associated with the asteroid 4 Vesta.

Where and when did the Bununu meteorite fall?

Bununu fell in Bauchi State, Nigeria, in 1942. The fall location is part of the meteorite’s formal identification and distinguishes it from other howardites found in different regions.

What does Bununu reveal about asteroid 4 Vesta?

Its eucrite and diogenite fragments represent material from Vesta’s ancient surface and interior. The mixed pieces also preserve regolith material, meaning loose soil and rock produced by impacts on the asteroid.

Why is Bununu called a polymict breccia?

A polymict breccia contains rock fragments from multiple source materials rather than one uniform rock type. Bununu fits that description because it combines eucrite and diogenite clasts in a howardite matrix.
