【Abstract】 The isograms and isogradient maps showing the distribution of the elements Fe, Mn, Al, Ca and Na in color-zoned tourmaline have been constructed. It is indicated that color zoning is correlated with compositional zoning in tourmaline. Changes in the composition of ore-forming solutions during crystal growth have also been deduced.更多还原
