| Description |
| Innenfor et tilnærmet sirkelrundt område med diameter ca. 100 m har det vært sporadisk drift. Maksimal avsenkning er 1 m i hele området. Granitten her er ganske lys. Lokalkjente mente driften hadde pågått til 1960-åra. Imidlertid var det tydelige spor etter oppdeling av blokk ved hjelp av kiling som var av ganske ny dato. |
| Location |
| Det største bruddet ligger på en fjellrygg ved Femdal, 70-80 m Ø for RV 108 mot Hvaler. |

| Abstract: | |
| This work is a report of granite and the granite industry in Norway. It contains a description of the various fields of granite and similar rocks from a scientific as well as from a technical and economical standpoint. The geological occurrence of the various rocks, their chemical and mineralogical composition, are thoruoughlyoughly treated, also the questions of practical interest, as the quality and other technical properties, further the problems of location and conditions for transport, conditions for quarrying and otherquestions of interest in the utilization of the various occurrences of granite. Granite: This chapter consideres first the mineralogical and chemical composition of the granite, and the various types of granite resulting from the varying composition; thereafter the most important structural types and how these are dependent on the geological appearance of the rock. Lakkolites and other froms assumed by granite masses when injected into the crust of the earth, are mentioned; some examples of beautifully formed lakkolites are also mentioned. The question of sheet structure and rift in the granite are of great importance in its utilization, and are of interest both practically and theoretically. |
