Shengus, Roundu District, Gilgit-Baltistan, Pakistan

The Shingus pegmatite region is one of the largest in Pakistan. It is related to the Indo-Pakistan plate in the zone of subduction of Precambrian gneisses of the Nangaparbat complex, which overlie Cretaceous amphibole-pyroxene granulites of the Kokhistan island arc.

There are several pegmatite fields in the Shingus region: 1) Shingus-Bulochi on both sides of the Indus gorge near villages of the same names, 16 km east of the junction of the Gilgit and Indus Rivers; 2) Haramosh near a peak of the same name, 15 to 20 km north of Shingus; 3) Stak Nala, 20 km east of Shingus village.
