The state of New Hampshire is divided into 10 counties. The counties are further subdivided into 13 incorporated cities, 221 incorporated towns, and 25 unincorporated places (townships, locations, grants, and purchases). New Hampshire bedrock is dominated by metamorphic and igneous rocks. Mining has been centered on monument grade granite, granite pegmatites (beryl, mica, and ceramic grade feldspar), sulfide ore deposits, and road metal quarries.
