RemarksR=0.015000 : DEF MIN =Leakeite :
The coordinates are those given in the paper but the atomic distances do not agree with those calculated during testing.The coordinates are probably correct.
Composition not given, assumed analogous to samples A(1) and A(2) from same rock specimen, cp. 64844 and 64845
Mean T-O: 1.621, 1.631, sample A(3), Bik from author, sigma(xyz)<=.0001, Fe stands for Fe+Mn (about 30%)
