Description |
Forekomsten opptrer i en lav åsrygg, der det har vært drevet brytning av granittisk gneis i mange år. Bergarten kan betegnes som en finkornet granittisk gneis, men representrerer trolig omdannete ryolittiske vulkanske bergarter. Bergarten har en sterkt utviklet stripning (foliasjon) og har utpregete kløvegenskaper som gjør den lett å splitte/dele. |
Examples |
Gjesåsgneisen benyttes svært mye til uteanlegg - murestein, kantstein og gatestein/tråkkheller. Den kan også benyttes til gulvflis. Eksempelvis er steinen brukt til kantstein og uteanlegg i Flisa sentrum. Bergarten er relativt porøs. |
Location |
Forekomsten ligger ved Gjesåsen, ca. 7 km nord for Flisa i Åsnes kommune. |
