Geiruvstjønn steinbrudd, Høvringsvatnet, Evje og Hornnes, Agder, Norge
Rock quarry for road fill material (aggreagates).
Most of the rock seems to be amphibolite/banded gneiss, but since this quarry is located in/near the contact zone with the granite/monzonite, there is widespread mixing and alteration. Probably a grateful study object for a petrologist.
For the mineral collector this quarry is hardly of interest. One specimen with tiny quartz and epidote crystals was found during a visit 17-07-2019.
The name has been given for a nearby lake, in accordance with the address displayed by the Norwegian state map.
