Bhutan
Bhutan lies in the Himalaya, where intense mountain-building produces metamorphic rocks, granites, and high-relief river systems. It’s an origin associated with gneiss, schist, quartzite, and a wide range of metamorphic minerals in regional contexts.
Notable stones & minerals
- Gneiss and schist (metamorphic basement rocks)
- Quartzite (hard, silica-rich metamorphic rock)
- Granite and pegmatite-related minerals (regional context)
Geology & regions
Bhutan’s geology reflects Himalayan collision: stacked metamorphic belts, shear zones, and intrusive granites. Rivers cut deep valleys that expose varied rock units and transport durable cobbles downstream.
Common uses
- Construction stone and aggregate (where permitted)
- River cobbles for local building and landscaping
- Educational reference for Himalayan metamorphism
Collecting & ethics notes
Mountain environments can be hazardous and access may be restricted. Collect only where legal and safe, avoid protected areas, and prioritize documented, responsibly sourced specimens.
