“The central granitic batholith defines the White Alps, a land of spires and glacially carved valleys with hanging lakes as a result. The eastern-most section is called the Red Alps because serpentine soils are common.”

Cornwall has a major advantage when it comes to alternative energy production: It sits atop a 280-million-year-old granite mass known as the Cornubian batholith, which is geologically ideal for producing geothermal energy.

The team’s research indicates the Spirit Lake batholith served as a plug in the Earth’s crust, diverting the magma.

Pink granite batholith circles Ensign Lake, and prehistoric “volcano bombs” — chunks of rock blown off the side of a volcano — lie at the bottom of Kekekabic Lake.

Monazite, together with a small amount of gold, is also known in the stream gravels of the Boise Basin, Idaho, where a large granitic batholith evidently carries the mineral sparsely distributed throughout.
