Gashua                                      12°51'N, 11°02'E

Dapchi, Nigeria

Fall: April 1984

History: The meteorite fall was reported by anonymous eyewitnesses to have occurred around April 1984 (about the time of the nearby Gujba fall) near the tiny desert settlement Kolomari close to the town of Gashua, Dapchi district, Nigeria.

Physical characteristics: A single stone of 4162 g was recovered and broken by villagers into many pieces at the place of the fall. The pieces were stored by villagers until they were collected in 2005 and sent to E. Twelker.

Petrography: (A. Greshake, NHB) The meteorite is a weakly weathered ordinary chondrite with recrystallized texture and few poorly defined chondrules. Opaque and often interconnecting shock veins are present.

Mineral compositions: Olivine (Fa23.8), pyroxene (Fs20).

Classification: Ordinary chondrite (L6); S4, W1.

Type specimens: A total of 40.4 g plus one polished thin section are on deposit at MNB. Twelker holds the main mass.
