Template:Short description Script error: No such module "Infobox".Template:Template other Adelie Land[1] is a meteorite discovered at 12:35pm on December 5, 1912, in Antarctica by Francis Howard Bickerton (1889-1954), a member of Sir Douglas Mawson's Australasian Antarctic Expedition, which took place between 1911 and 1914.[2][3] It was named after Adélie Land, where it was found, and it was the first meteorite found in Antarctica.[4] The meteorite was found approximately 20 miles from the base at Cape Denison, lying in the snow in a shallow depression.[3][5]
Composition
One fragment was found, which weighed Script error: No such module "convert". before it was sliced for examination by the scientists on the base. Afterwards, the specimen weighed Script error: No such module "convert".. The specimen was listed in the scientific report, published in 1923 as being "a little elongated in one direction, being Script error: No such module "convert". long, Script error: No such module "convert". broad, and Script error: No such module "convert". high. It has rather a pointed nose, and a broad, smoothly sloping tail."[5]
The surface of the meteorite is covered with a dark brown/black crust, with some chips and cracks visible. As the meteor was sliced for study, we are able to see the core, which contains flecks of nickel-iron metal.[5][2]
It was classified as L5 ordinary chondrite. The meteorite is roughly 3.49 Ga old.[6]
Display
Chemical analysis of the meteorite was carried out in the Laboratory of the Geological Survey of Victoria.[5] After the analysis of the meteorite, and subsequent publication of scientific reports in 1923, the specimen was donated to the Australian Museum for display, where it remains to this day.[7][2]
