Description
Dette er et av de største av de gamle bruddene i Oslo-marka. Arealet er ca. 60 m x 30-40 m, og største avsenkning er 3 m. I likhet med andre brudd i området antas steinen å ha blitt brukt til hus- og forstøtningsmurer nede i byen.
Location
Her er et større bruddområde beliggende nord-vest for Svartkulp. "Skogsvei" fra Sognsvann går her i nord-nordøstlig retning og går rett gjennom bruddområdet.

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.
