I Geologisk Museums gård ligger meteoritten Agpalilik.

I 1963 drog Vagn Fabritius Buchwald på ekspedition til Nordvest Grønland. Her fandt han under en frokostpause en stor rusten sten. Meteoritten blev døbt Agpalilik, Manden, og blev bragt til København på slæden som den stadig ligger på. Den er en del af Cape York meteoritten der faldt for omkring 10.000 år siden. Der blev brugt over 200 timer på at skære en skive af Agpalilik, og som i dag er udstillet inde på museet og hvor man tydeligt kan se Widmanstätten mønstret som kun findes i meteoritter. Der er blevet fundet en del rester af Cape York meteoritten, i alt omkring 58 tons, hvor en del er i København, og andre i New York. Med 20,1 tons er Agpalilik den tredje største meteorit fundet i verden.

Meteoritter er himmellegemer der har klaret turen igennem jorden atmosfære uden at brænde helt op. Når en meteorit bevæger sig igennem atmosfæren er der tale om et stjerneskud. Traditionelt er meteoritter blevet opdelt i jernmeteoritter, der primært består af jern og nikkel. Stenmeteoritter der mestendels består af silikater, og jern/stenmeteoritter der en mellemting.

For at logge dit fund skal du svarer på følgene spørgsmål og sende dem i en mail til mig. Du behøver ikke at vente på svar før du logger, men det vil være nemmest hvis I svarer og logger på samme dag. Er du i tvivl vil jeg meget gerne hjælpe så bare send mig en mail.

1) Beskriv Apgpalilik. Hvilken farve, form osv.

2) Hvilken slags meteorit mener du der her er tale om, og hvad ligger til grund for dit svar?

3) På den skårne side er der nogen afrundede plamager, hvor lang/høj er den største?

Hvis du har tid vil jeg anbefale at du tager et smut ind på museet hvor du bl.a. kan se verdens største stykke naturligt sølv fra Kongsberg i Norge.

ENG:

In the yard of Geological Museum lies the meteorite Agpalilik.

In 1963, Vagn Fabritius Buchwald lead an expedition the Northwest Greenland. During a lunchbreak i saw a large stone covered in rust. The meteorite was named Agpalilik, the Man, and was brought to Copenhagen on the sledge where its still resting. It is a part of the Cape York meteorite which fell around 10,000 years ago. More than 200 hours were spend cutting a slice of Agpalilik. This slice, the largest in the world in now on exhibit inside the museum. On it one can clearly see the Widmanstätten pattern which is only found in meteorites. Quite a few pieces of the Cape York meteorite has been found, all together 58 tons, where some are in Copenhagen, others in New York. With its 20.1 tons, Agpalilik is the third largest meteorite found overall.

Meteorites are natural objects which makes it through the earths atmosphere without burning up. When a meteorite moves through the atmosphere it is seen as a shooting star. Traditionally meteorites are divided into three kinds. Iron meteorites, which are mainly iron and nickel. Stony meteorites, which are mainly silicate minerals. And stony-iron meteorites which are a mixture.

In order to log your find please answer the following questions and mail the answers to me. You do not have to wait for permission to log, but it is easiest for me if you send the answers and log on the same day. If you have any difficulties don’t hesitate sending me an e-mail.

1) Describe Agpalilik. Which color, shape and so on.

2) Which type of meteorite do you think it is, and what is your reasoning?

3) On the cut of side there are some rounded markings, how long/high is the largest one?

I will recommend a visit to the museum itself where you among others can view the worlds largest piece of natural silver from Kongsberg in Norway.
