Wyoming batholith
The Wyoming batholith is a granite batholith of Neoarchean origin 2,800 to 2,500 million years ago—which forms the eroded core of the Granite and Laramie Mountains in central Wyoming.[1] The Wyoming batholith lies within the Wyoming Craton. The batholith, in its time, was a magma chamber. Contemporary magma chambers are filled with lava and buried deeply and are inaccessible. The Wyoming batholith is accessible for study, its overburden having eroded away.[2]
