The Zakłodzie meteorite is a stony-iron meteorite found in Poland in 1998. Its mass is 8.68 kilograms (19.1 lb). It is composed predominantly from enstatite and meteoric iron. Currently classified as an ungrouped enstatite achondrite its classification is still an ongoing scientific debate.[2]

Naming and history

The Zakłodzie meteorite was found beside a dirt road by Stanisław Jachymek who was searching for fossils and rocks. The site lies south of the village Zakłodzie (Lublin Voivodeship), after which the meteorite is named.[3][4]

A fireball, which may well have been the Zakłodzie meteorite, was seen in the area of the find on 21 April 1897; its weathering is consistent with such an age.[5] As of 20 December 2012 part slices were on sale at US$100/g.[5]

Mineralogy

The meteorite is composed of 60%

chondrules. A second interpretation is that the textures are a result of cumulate crystallization or an impact-melt breccia.[2][8] It's the type locality of two minerals: browneite (IMA 2012-008) and buseckite (IMA 2011-070).[6]

Classification

The meteorite was classified as an "ungrouped enstatite-rich meteorite" in 2000.[7] In 2005 it was proposed that the meteorite was the product of magma crystallization and therefore an achondrite. The magma originated from the partial melt of an enstatite chondrite source. It was therefore proposed that the Zakłodzie meteorite should be classified as a "primitive enstatite achondrite".[8] It was classified as an Aubrite-an (anomalous) in 2006.[1] Currently the recommended classification is that the Zakłodzie meteorite is an ungrouped enstatite achondrite.[1][9]

Some scientists propose that many

quenched (a quick decrease in temperature). This could happen during impact events on the surface of the parent body.[10]
