Orud grube var en av de største anleggene for feltspat (Broch, 1934) og ble åpnet rundt 1880. Den har vært i drift i flere perioder og produserte nesten utelukkende alkalifeltspat. Etter noen års driftshvile ble driften gjenopptatt i 1931-1933. Broch (1934) beskriver sydveggen slik: "Pegmatitten er meget grovkornet med store kvartsmasser og alkalifeltspatstolker. Der ses litet av plagioklas og og litet muskovitt, derimot en del store biotittkrystaller. Videre er funnet litt svovlkis samt et mineral som efter beskrivelsen synes å være molybdenglans." Orud 2 Broch(1934) skriver 100 m sydsydøst for overnevnte ligger et nyere, adskillig mindre brudd, som har været nedlagt siden 1903. Der sees nu en vannfylt synk ca 25 m lang, 8 m bred og angivelig 15 m dyp. Bruddet er noeget krokete, hovedretningen nordvestlig. |

Abstract: | |
In this publication, which is a sequel to Feltspat II and III by Olaf Andersen and Tom F.W. Barth, brief and exoteric descriptions and some information on production and history are given of about 180 individual feldspar, quartz, and mica deposits, all of them situated east of the river Glomma in south-eastern Norway. Particulars of purely geological or mineralogical interest are few; most of them are given as footnotes or in the preface, but the minerals of each deposit, exceot quartz, feldspar and mica, are listed. The deposits are cross cutting pegmatite dikes, with a northeastern strike and a steep dip. The dikes exhibit a marked zoning; moreover, they are remarkably free from rare minerals, the occurrences of which seems to be restricted almost entirely to the dikes near the Idefjord (Bohus) granite. |
