Hello All, Carl2, you memory serves you right!
The color of LDG is affected by: 1) its very high silica content (almost pure silica: 98%). A decreasing silica content correlates with a gradual change of color from yellow over green towards brown. and, ... this has to do with no. 2: 2) the total iron content and by the Fe(II)/Fe(III) ratio. Best wishes, Bernd ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
