Description |
Steinbrudd i omdannet sandstein. Produksjon av murestein og 5-10 centimeter tykke plattingsstein/heller. Sandsteinen er grå til beige, og spalter langs lagningen til tykke emner og plater. Rektangulært sprekkemønster gir godt utbytte av murestein. Forekomsten har store reserver både i dypet og i sandsteinssonens laterale utbredelse. |
Location |
Bruddet ligger like vest for veien mellom Grimstad og Herefoss, 1 km N for Snøløsvannet. |
