The Ljusdal Batholith is a group of plutons in central Sweden formed during the Svecofennian orogeny. The batholith occupies a NW-SE elongated area of c. 130 x 100 km covering most of Hälsingland.[1] The Ljusdal Bathoilith is mostly made up of granitoids with lesser amounts of mafic intrusions.[2]

The plutons of the batholith crystallized from magma 1840 to 1860 million years ago in Paleoproterozoic times at an ancient convergent boundary.[2]
