Description

Hovedbruddet ved enden av veien er 50-100 m i diameter med 10-15 m avsenkning. Mellom hyttene noe lenger vest og syd i området er det flere mindre brudd. Bergarten er rødlig, lys, middelskornet granitt. Mye stor blokk ligger igjen i det største bruddet (murestenproduksjon?), men også materiale som tyder på gatestenproduksjon ligger ved bruddene.

Location

En sidevei tar av fra RV110 ca. 3 km vest for Skjeberg og går sydover langs Skjebergkilen. Ved Olseng tar en privat vei av mot vest inn i et hytteområde. Etter ca. 1 km tar en vei av som etter hvert svinger nordover. Ved enden av denne veien ligger bruddene.

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.
