Xenoblastic refers to metamorphic mineral with poorly formed crystal faces (equivalent to anhedral). Foliation is a general term for pervasive planar structures. Typically the result of fine-scale compositional layering and alignment of minerals.
Habitat and range. Snowy owls live on arctic tundra, open grasslands and fields, and even on frozen stretches of water. When they migrate into northern Minnesota they are sometimes seen hunting for food in railroad yards and other city areas. They usually perch on the ground or on buildings or utility poles.
During the breeding season, which snowy owls spend in the Arctic, they nest on small rises in the tundra where the female carves out a scrape or shallow depression in the ground in which to lay her eggs. FACT: Snowy owls are not entirely white.
