Photomicrograph of a Hornblende Granite slide section, cross polarized lighting
Also called Syenitic granite, contains hornblende as well as mica. Granite, a holo-crystalline quartz-bearing plutonic rock, has between 10 - 50% of quartz as its component, the alkali feldspar/total feldspar in the ratio between 65 to 90%, and the modal concentration of other minerals is less than 10%. The cutting of granite has been made easier by the use of steel abrasives. Use of such tools enhances cutting of granite, saves time and lends smoother edges. The granite is cut into thin slabs by multi-blade gangsaws, and using various types of granite cutting blades available in the market
