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.
Where do they live? Barn owls are the most widespread of all owl species, and are found on every continent except Antarctica. In the Americas, barn owls occur in suitable habitat throughout South and Central America, and in North America as far north as the northern United States and southwestern British Columbia. In Europe, barn owls range from southern Spain to southern Sweden and east to Russia.
