1959 C. Milton et al. in Bull. Geol. Soc. Amer. 70 1646 Norsethite, BaMg(CO3)2, was found in dolomitic, black oil shale below the main trona bed in the Westvaco trona mine... Norsethite is named in honor of Mr. Keith Norseth, engineering geologist of the trona mine at Westvaco, Sweetwater County, Wyoming.
1968 I. Kostov Mineral. ii. xi. 540 Norsethite is probably trigonal-trapezohedral with distinct rhombohedral {1011} cleavage.
1986 Geology 14 409/1 Norsethite and PbMg(CO3)2 were obtained as major constituents.
1997 Mineral. Mag. 61 249 The results are compared with those for natural norsethite from Långban (Sweden) and Rosh Pinah (Namibia). The Raman spectrum of synthetic norsethite is reported, too.
