Description |
Det finnes tallrike større og mindre nedlagte brudd i forekomsten. Mest kjent er de store bruddene ved sjøen der blokk til bl.a. Vigelandsanleggene ble tatt ut. Så godt som overalt der det er bart fjell i dagen har det vært en eller annen form for tidligere bruddaktivitet og store mengder med rester fra gatesteinsproduksjon ligger igjen mange steder. Forekomsten er nærmere 3 km lang og 1,5 km bred. Benketykkelsen er normalt større enn 1,5 meter, avstanden mellom steile sprekker normalt mer enn 2 meter. Sentralt i dette området finnes et parti med særlig homogen og massiv granitt. En benketykkelse på opptil 5 meter er her ikke uvanlig. Granitten er middels- til grovkornet og grå med brunlig skjær. |
Examples |
Granitten har blant annet vært blant de viktigste i Vigelandsannlegget, og Monolitten er laget av granitt herfra. Granitten er sterk og holdbar, men i partier i forekomsten finnes svovelkis. Slike kvaliteter kan lett misfarges ved rust. |
Historical significance |
I dette området ligger steinbruddene der Monolitten i sin tid ble tatt. Flere av de gamle bruddene, særlig langs sjøen, har klart kulturhistorisk verdi. |
Location |
Forekomsten ligger ca. 4 km rett syd for Halden sentrum, mellom Idd og Iddefjorden. |

Granittforekomster i Halden kommune. |
;Norges geologiske undersøkelse;RAPPORT;NGU-rapport; No.99.061;17 pages |
Abstract: | |
Rapporten gir en oversikt over de industrielle aspekter ved natursteinsdrift og variasjonen i Iddefjordsgranitten med hensyn til dens potensiale som naturstein. Ved Iddefjorden har granitten en lengde og bredde på henholdsvis ca. 20 og 4 km. Fra polerte prøveplater har vi delt granitten inn i følgende typer: Type A er middelskornet og noe rødlig i farge og har sin største utbredelse rundt brekke. Type B er middels til grovkornet og grå av farge og opptrer i området Hov-Folkvang-Skriverøya. Type C er lik type B men har en mindre kornstørrelse og finnes i området fra Berby og sørover. Type D er markert forskjellig fra alle andre og er finkornet og lys grå av farge, den finnes i området rundt Liholt. Basert på oppsprekking har vi delt inn granitten i følgende klasser: Klasse 1 (mest massiv) har mer enn 1.5 meter benketykkelse og 2-3 meter mellom vertikale sprekker. Klasse 3 (mest oppsprukket) har mindre enn 1.5 meter benketykkelse og 2-3 meter mellom vertikale sprekker. Granitt av klasse 2 finnes i en smal sone i Hovområdet samt ved Skriverøya; her er det mulig å finne forekomster med liten skrotprosent og stor blokk. Granitt av klasse 2 har ganske stor utbredelse, spesielt vil vi påpeke området nord for Brekke. Her er det mulig å finne forekomster som kan produsere stor blokk, men skrotprosenten vil nok bli høyere enn i området med klasse 1. I områder der granitten er av klasse 3 tror vi det er vanskelig å etablere lønnsom blokkproduksjon. |

The Iddefjord granite: geology and age |
;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU Bulletin; No.417;55-64 pages |
Abstract: | |
The Iddefjord granite forms part of the Swedish Bohus batholith and ranges in composition from diorite to granite. The granite consists of 13 individual plutons, and the mechanism of intrusion is related to block subsidence rather than forceful intrusion. There is no evidence of marginal chill, and the temperature of the host gneiss must have been similar to that of the granites. This suggests that the intrusion took place in a regionally pre-heated rock complex under plutonic conditions. The major element trends of the granites are similar to those of recent granite batholiths. Rb-Sr age determinations carried out on two of the granites yield a common isochron age of 918+- 7Ma with an initial Sr isotope ratio of 0.7063 +- 0.0008 suggesting contributions from older crustal components. Mineral analyses from one of the investigated granite samples indicate a Rb/Sr mineral age in the order of 835 Ma, reflec- ting either a slow cooling of the pluton or a younger thermal effect causing resetting of the mineral system. |

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 |
Blokka som Monolitten i Frognerparken er hogd ut av ble hentet fra dette bruddet. Diverse kraner og trallebaneskinner ligger igjen og vitner om at her har vært uttak av store blokker. |
Location |
Bruddet ligger helt i sjøkanten sydvest for Hov. |
