THE GLADSTONE–DALE COMPATIBILITY OF MINERALS AND ITS USE IN SELECTING MINERAL SPECIES FOR FURTHER STUDY

Joseph A. Mandarino
Published: 01 October 2007
The Canadian Mineralogist (2007) 45 (5): 1307–1324.
DOI: https://doi.org/10.2113/gscanmin.45.5.1307
... The data used to calculate the Gladstone–Dale compatibility of the germanate minerals were taken from the International Encyclopedia of Minerals, which contains descriptions of three such species. The species and their compatibilities are: bartelkeite: −0.181 P, carboirite: 0.079 P, eyselite: indices...
