Saga 1 Quarry, Sagåsen (Strandåsen), Mørje, Porsgrunn, Telemark, Norway

Larvikite Quarry that laid at a higher level, where the Sagåsen Quarry is today, also with a large nepheline-syenite pegmatite, but different from the one in Sagåsen (Saga 3). The Saga 1 pegmatite was worked out, and disappeared with the quarry. More than 70 different species have been found in the Saga 1 pegmatite, approximately 40% of all minerals found in the syenite pegmatites in the whole Oslo Region. It was especially rich in Be-minerals, with 12 different species. The pegmatite also became famous for huge individuals of certain minerals: Biotite - 50-70 kg, leucophanite - several kg, mosandrite crystals - ¾ m in length, thorite - several kg, nepheline - several hundreds of kg, böhmite crystals - 3 mm.
