...Christian CHOPIN; Giovanni FERRARIS; Mauro PRENCIPE; Fabrice BRUNET; Olaf MEDENBACH Abstract The new mineral raadeite, Mg 7 (PO 4 ) 2 (OH) 8 was found in nodules of apatite + Mg-phosphates within the Tingelstadtjern serpentinite body, Modum district, Norway. It occurs as veinlets, a few tens of μm...

...Peter Robinson; Falko Langenhorst; S.A. McEnroe; Karl Fabian; Tiziana Boffa Ballaran Abstract Extensive negative aeromagnetic anomalies in the Modum area, south Norway, derive from rocks containing ilmenite with hematite exsolution, or hematite with ilmenite exsolution, carrying strong/stable...

...J. Låg Abstract The scope of geomedicine is briefly discussed. An interest in geomedical problems has existed in Norway since the last century, involving goitre in dry inland regions ( I deficiency), and osteomalaci in cattle (P deficiency). Geographical variations in precipitation chemistry...

...J. B. Gammon Abstract Fahlbands--concordant layers or lenses of sulfidic impregnation in a metamorphic sequence--are interpreted as the high-grade metamorphic equivalents of sapropelic sulfide muds. In the Kongsberg silver and Modum cobalt districts of southern Norway, the fahlbands were present...
