Description

Bruddet er 50-60 m langt, 20-30 bredt og 7-8 m avsenkning i bakkant. Det er tilnaærmet plant i bunnen, og brukes i dag til oppbevaring av vrakgods etter lastebil- og anleggsvirksomhet (se bilder). Drammensgranitten her er en betydelig blekere variant enn i Åssida nord for Drammen, og som er mest vanlig for Drammensgranitt. Benketykkelsen er 2-3 m.

Location

For å komme til forekomsten må en ta av fra riksvei 283 og kjøre over jernbanelinja på gårdsvei mot Narverud. Der veien deler seg må en ta vei lengst til venstre, og en vil finne forekomsten like etter siste veikrysset.

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

Ca. 50 videre langs veien ligger dette bruddet som er ca. 20 m langt med bruddåpning mot veien. Bruddveggen i bakkant er ca. 2 m. Liksom hovedbruddet er dette sterkt overgrodd og ikke lett å se ved første øyekast.
