Preventing ear hematomas means getting your dog in to the veterinarian anytime you notice a potential problem with the ears. Here are some of the signs of an ear problem that might lead to a hematoma:
Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar (see below) is known as anorthosite.Feldspars are also found in many types of sedimentary rocks.he name feldspar derives from the German Feldspat, a compound of the words Feld, field, and Spat, a rock that does not contain ore . The change from Spat to-spar was influenced by the English word spar, a synonym for mineral. Feldspathic refers to materials that contain feldspar.
All these minerals are also silicates. In other words, quartz is a silicate made of pure silica. But feldspars contain sodium, aluminum, potassium and calcium in addition to silicon and oxygen. Thus feldspars are silicates but they aren't pure silica.
