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.
Feldspar. Feldspar is the mineral name given to a group of minerals distinguished by the presence of aluminum (Al) and the silica ion (SiO4) in their chemistry. This group includes aluminum silicates of soda (sodium oxide), potassium (potassium oxide), or lime (calcium oxide). Feldspar is the single most abundant mineral group on Earth. Together, the varieties of feldspar account for one half of the Earth's crust. The minerals included in this group are orthoclase, microcline, and the plagioclase feldspars. They form in a variety of thermal environments, during the crystallization of liquid rock (magma), by metamorphism of rocks deep in the earth, and in sedimentary processes.
