| Broch (1934) omtaler denne som Greåker 2 ("Bjørndalen") m.fl. Bruddet ble åpnet rundt 1885 og har senere vært drevet av flere, sist i 1932. Vesentlig kvartsproduksjon. Det finnes også en rekke andre små skjerp og prøvebrudd i pegmatitter i området. Broch(1934) nevner også et kvartsbrudd sør for Rundemyr. Vannfylt synk 7x15 m vid, dybde ukjent. Denne ble trolig drevet i 1890-årene og periodevis frem til senest 1932. |

| 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. |
