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.
Feldspathoid group. The feldspathoids are not a typical mineral group like other mineral groups that are related by structure and chemistry. Their relation to each other is due primarily to their relationship to the feldspar group of minerals.Feldspathoids are low silica igneous minerals that would have formed feldspars if only more silica (SiO2) were present in the original magma.The aluminum to silicon ratio is nearly 1:1 in most of the feldspathoids but is closer to 1:3 in most of the feldspars.eldspathoids are low silica igneous minerals that would have formed feldspars if only more silica (SiO2) were present in the original magma.
