<P> Granite containing rock is widely distributed throughout the continental crust . Much of it was intruded during the Precambrian age ; it is the most abundant basement rock that underlies the relatively thin sedimentary veneer of the continents . Outcrops of granite tend to form tors and rounded massifs . Granites sometimes occur in circular depressions surrounded by a range of hills , formed by the metamorphic aureole or hornfels . Granite often occurs as relatively small , less than 100 km2 stock masses ( stocks ) and in batholiths that are often associated with orogenic mountain ranges . Small dikes of granitic composition called aplites are often associated with the margins of granitic intrusions . In some locations , very coarse - grained pegmatite masses occur with granite . </P>
