QEMSCAN mineral map of kimberlite
Nothing but a beautiful picture on a Monday morning. This is one of my all time favourite QEMSCAN images: a kimberlite from South Africa donated to Intellection Pty. by De Beers in 2005. The kimberlite mineral map is emphasising olivine macrocrysts (in green) spectacularly altered to various generations of serpentine. The kimberlite matrix is made up of clay minerals and carbonates, presented in blue, purple and buff colours.
