Glørud gruve ligger ca. 350 m sør for gården Glørud og inne i skogen ca. 50 m øst for veien sørover fra gården. Arbeidene som er synlige nå består av en vann- og bildekkfylt synk med sidevegger på 3 x 3 m. Synken og området er svært overgrodd og det finnes ingen blotninger i området. Gruva er imidlertid godt markert med et skilt; Nikkelgruve. Det har trolig vært gjort en god del arbeid ved gruva da et område vest for synken med et areal på ca. 300 kvadratmeter (10 x 30 m) består av gjengrodde tipphauger i skogen. Mineraliseringene består av disseminasjon og strenger av magnetkis og mindre mengder kobberkis i finkornet, foliert amfibolitt. Ifølge Norges Bergverksstatstikk produserte Glørud interessentskap nesten 2.000 tonn nikkelmalm i perioden 1875-77, trolig fra flere forekomster i området (f.eks Ruene).

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.

Abstract:

The territory is situated in south-eastern Norway to the east of the Oslofjord. It is an inland district which at no place reaches the sea. Glomma is the chief river which runs through the country in a southerly direction. The rocks occurring here are gneiss, granite, gabbro and schistose amphibolite, all of them of Archean age. Gneiss occupies a large area of the region. The rock has a varied appearance. Partly it is rich in mica (mica gneiss), partly it contains hornblende (hornblende-gneiss), partly it is coarse-grained and of granitoid texture. This latter form embraces also granite which has been deformed by powerful mechanical forces. This granite is intermixed with the gneiss in such a way as to make it impossible to separate them on the map. For the most part there is no distinctive demarcation between them, but the one passes into the other. The gneiss is mostly stratified, with well defined strike and dip. The granite intermixed is younger than the gneiss, but it belongs to the oldest known granites of Scandinavia. The gneiss is for the most part of igneous origin. Gabbro and amphibolite occur as numerous lenses injected into the gneiss. Connected with the gabbro here occurs nickelferous pyrrhotite. The greatest of these occurrences is at Romsås.
