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!

The Middleton-Yakataga Basin is a collective term for these two medium Cenozoic foreland basins and the Yakutat Terrain, which lie in the Gulf of Alaska, southern Alaska. They are bordered on the north by a series of thrust faults
associated with the Kenai-Chugach Mountains and the St. Elias Mountains, on the east by the Fairweather Fault Zone, on the south by the Transition Fault Zone (of Kirschner, 1994), and on the west by thrust faulted and highly deformed strata that underlie Prince William Sound. The three basin areas are compartmentalized by major fault zones
