| Abstract/Notes | A description is given of varieties of woodhouseite and whitlockite found in specimens from the apatite-rich veins cutting the Precambrian rocks at Ødegårdens verk, Bamble, S. Norway. The minerals occur, together with quartz, in pockets within a matrix of chlor-hydroxy-oxyapatite. Physical and optical data are given for both minerals, together with x-ray powder diffraction data. A semi-quantitative spectrographic analysis of the whitlockite is included. The woodhouseite is a purple variety with lattice dimensions of ah 7,001, ch 16,265, c/a 2,325, ar 6,76 and < a 62° 22'; its optical constants are Ne = 1,669 ( ±0,003), NO = 1, 662 ( ± 0,003), Ne -NO 0,007 ( ± 0,003), uniaxial positive (or occasionally biaxial with 2V of 10° to 20°). An unidentified alteration product after woodhouseite is also described. The whitlockite is a green variety, containing approximately 0,3% V2O5, with optical constants: NO = 1,620 ( ± 0.003), Ne = 1,623 ( ± 0,003), Ne - NO 0,003 ( ± 0,003), uniaxial negative. It is concluded that the minerals in these pockets represent either final residual products of crystallisation within the apatite vein or that they were formed during a later period of metamorphism, metasomatism and hydrothermal activity which may have affected the apatite veins. | ||
