history

Around 1940 eyewitnesses saw a swarm of meteorites moving across the sky from north to south. The meteorites fell in the rubber plantation Soemboer Wadeok, which was about ten kilometers south of the town of Kediri , a town in the Indonesian province of Jawa Timur (German: East Java ). The workers on the plantation collected 70 meteor stones of different sizes. In 1935, only five years earlier, another meteorite came down 55 kilometers west of Kediri, the Madiun meteorite .

The eyewitness, on whose report a publication of the case history in 1975 in the Meteoritical Bulletin is based, a Mr. Treur, administrator of the plantation, died in 1965. Treur assumed that the meteor swarm would plunge into the ocean because it disappeared behind a mountain. The pieces picked up by plantation workers were sent to Amsterdam and from there distributed to the Teylers Museum in Haarlem (The Netherlands ), Arizona State University and the Natural History Museum in London .

Appearance and classification

Kediri is a common chondrite . Chondrites are stone meteorites with inclusions of minerals . It has been categorized as H-chondrite. The rock has chondrons , which are mineral spheres as inclusions that can be seen quite clearly, which is why Kediri was classified as L4 chondrite. Metal inclusions can also be clearly seen on him.

The stones picked up have a total weight of 3.3 kilograms.

A one-sided brown-black melt crust suggests that the meteorite broke apart in high atmospheric layers of the earth.
