Formula:
Al9(PO4)8(OH)3 · 27H2O
Colour:
white
Crystal System:
Orthorhombic
Name:
Named for Henryk Arctowski (1871-1958), Polish Antarctic researcher in the Belgica Antarctic Expedition (1897-1899). The Polish Antarctic research station is named for him, as well as Arctowski Peak and Arctowski Peninsula.
Plastic 'clay' composed of well-defined rhombohedral crystals 2-5µm in dimension, usually twinned with angles 74° and 106° in books, surrounded by taranakite.
Originally described from Low Head, King George Island, South Shetland Islands, Antarctic Peninsula, Western Antarctica, Antarctica.
