Description |
Bruddet er ganske lite, og det antas at det har vært tatt ut stein til lokalt behov (hus- og forstøtningsmurer i Oslo). Bergarten er en ganske skarp rød nordmarkitt med inneslutninger av metasedimenter. Benkning/horisontale sprekker har en avstand på ca. 0,5 m, og vertikale sprekker en avstand på 2-4 m. Noen blokker ligger igjen etter driften. |
Location |
Forekomsten ligger øst for Songsvann, ved gangsti mellom Songsvann og Svartkulp. |

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. |

Description |
Forekomsten ligger ca. 100 m nordøst for hovedforekomsten (OS0002). Dette er ei lita grop hvor en kan se det er sprengt ut noe blokk. Det er ganske tett skog i området, og bruddet er ganske overgrodd. |

Description |
Syenitten er noe blekere her enn i sørenden av Sognsvann. Noe større blokk er tatt ut her,- muligens til husmurer. |
Location |
Bruddet ligger i ei bratt li nordøst for Sognsvann. Vei fra parkeringsplassen sør for Sognsvann går like ned for forekomsten. |

Description |
Det er brutt noe stein over et større område, men det er ikke gått i dybden noe sted. Bergarten er rød nordmarkitt med bleke forvitringsflater. Total lengde på uttaksområdet er ca. 300 m. Det har sannsynligvis blitt produsert små blokk eller gatesten. |
Location |
Området ligger vest for Sognsvann. |
