Oppdal Quarzit

Über Oppdal Quarzit

Oppdal Quartzite (German: Oppdal Quarzit) is a Precambrian mica quartzite (Glimmerquarzit) quarried in the Oppdal municipality, Trøndelag, Norway. It is one of the most well-known Norwegian decorative stones, heavily used in Germany and across Central Europe for exterior paving, cladding, stairs, and flooring. The stone is silver-grey with a largely non-directional (isotropic) fabric, and typically finished in sawn, split, or natural surface rather than polished. DNSA (Stein 403, 914) provides authoritative technical data: density 2650–2730 kg/m³, compressive strength 175–260 MPa, flexural strength 25.2–47.0 MPa, water absorption 0.25%. Multiple named product variants exist: Oppdal Golan, Oppdal Furunes, Oppdal Trollheimen — all share the same Oppdal quartzite geology but differ in quarry zone and appearance.
