    Granite Quarrying in Maine Maine Geological Survey Quarry Methods Granite was quarried using steam drills, wedges and hammers. Steam drills (modern quarries use jet drills) drilled holes along the hard edge of the granite, perpendicular to the grain of the rock (Figure 4). Figure 4. Tayntor Quarry, Hallowell. Looking along grain at steam drill holes.

    UsageSignificanceGeologyDefinitionsFeaturesApplicationsAdvantagesOther usesFormationGranite is a coarse-grained, light-colored igneous rock composed mainly of feldspars and quartz with minor amounts of mica and amphibole minerals. This simple definition enables students to easily identify the rock based upon a visual inspection. Granite is a plutonic rock in which quartz makes up between 10 and 50 percent of the felsic components and alkali feldspar accounts for 65 to 90 percent of the total feldspar content. Applying this definition requires the mineral identification and quantification abilities of
