Chondrodite
WebChondrodites contain up to 9.1 wt% TiO 2 and clinohumites about half that amount. The maximum amounts of Ti in both minerals do not exeed values of 0.4 in the formula. XTi and X F are correlated by a slope of −1, indicating the efficiency of the TiO 2 Mg −1 F −2 substitution at constant OH ( Evans and Trommsdorff, 1983). http://classicgems.net/gem_chondrodite.htm
