Forekomsten oppgis å ligge ca. 7 km sør for Lundeby, like øst for sydenden av Kulevann. Forekomsten er en rund synk med omtrent 5 meter i diameter og 10 meter dyp. Det er beskrevet stolper av 1 meters tverrrsnitt med alkaliefeltspat og glimmerkrystaller med 20 cm størrelse. Forekomsten var i drift noen år fra 1895. |
Location |
Lundeby, også omtalt som "Kulevannsgruben", blir av Broch (1934) beskrevet som "ligger omtrent 7 km syd for Lundeby (i Hærland) i utmark nær toppen av en liten amfibolittkolle like øst for sagen ved sydenden av Kulevann. Basert på denne beskrivelsen og digital terrengmodell bør denne flyttes til UTM sone 33 302560Ø 6599266N i sørenden av Spattåsen. |

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. |
