TitleFeldspar crystals
DescriptionThe feldspar group is a fairly large group with nearly 20 members recognized, but only nine are well known and common. Those few, however, make up the greatest percentage of minerals found in the Earth's crust. They have a rather dull to rarely vitreous luster. Crystals tend to be blocky as the picture shows.
LocationUSA ▹ Oregon. Oregon Mountains, west side of White Sands.
