Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite
Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!

1.5 Ga old carbonatite dyke. The Attu carbonatite dyke is located at the southern end of Uperniviarsuk island approximately 10 km NE of the village Attu between Sisimiut and Aasiaat in southern West Greenland. The bedrock in the area is mostly Archaean in age, mainly comprising tonalitic to granodioritic gneisses, which have been overprinted by a regional amphibolite to granulite facies metamorphic event at ca. 1850 Ma. The pinkish carbonatite body occurs as an up to 1 m wide, steeply to vertically dipping dyke that strikes in NW-SE direction at 128° and can be traced for approximately 50 m along strike. Close to the northeastern contact, it occurs between a 20 m thick NW-SE trending, steeply dipping meta-dolerite dyke and granulite facies gneisses that dominate the basement in the area.

Knudsen et.al state that: "[t]he Attu carbonatite dyke is located at the southern end of Uperniviarsuk island approximately 10 km NE of the village Attu between Sisimiut and Aasiaat in southern West Greenland." [Note: If this is the case then this places the locality in the municipality of Qeqertalik].
