Description
Hovedbergarten er Grefsensyenitt, men den har store inneslutninger av hornfels, og det antas at det i siste del av driftstiden i tillegg til natursten har vært produsert pukk her.
Location
Dette er et stort brudd (ca. 100 m i diameter og 10 m avsenkning) beliggende like øst for Greibanen 1og bebygd med boligblokker og rekkehus.

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
Store mengder stein er tatt ut. Diameter på bruddet er 50 m og avsenkningen 10-15 m. Bruddet er i dag bebygd med en større blokk som inneholder både kontorer og boliger.
Location
Bruddet ligger ca. 200 m nord for kryss mellom riksvei 4 og tilførselsvei til Ammerud. Det ligger like vest for nevnte tilførselsvei.

Description
Nok et brudd som er blitt hustomt. Her står en enebolig i dag (Lilloseterveien 16). Avsenkningen er ca. 10 m, men det vanskelig å anslå arealet.
Location
Bruddet ligger ca. 100 m nordvest for Ammerud 2, på et 20-30 m høyere nivå i terrenget.
