What is On the Optically Biaxial Character and Heterogeneity of Anthracites about?

The results of the study of optical properties of 13 anthracites from different parts of the world are presented in this paper. Measurements of reflectance values were made on non-oriented vitrinite grains for a minimum of 300 points per sample. The reconstruction of Reflectance Ž . w Indicating Surfaces RIS were made by Kilby's method Kilby, W.E., 1988. Recognition of vitrinite with non-uniaxial negative reflectance characteristics. Int. J. Coal Geol. 9, 267-285; Kilby, W.E., 1991. Vitrinite reflectance measurement -some technique enhancements and x relationships. Int. J. Coal Geol. 19, 201-218 . It was found that the use of Kilby's method for strongly anisotropic materials like anthracites did not give unambiguous results. Some improvement in Kilby's method, consisting of the division of the cumulative cross-plot into several elemental components, is suggested. Each elemental cross-plot corresponds to a textural class of anthracite, which is characterized by the values of RIS main axes 2, . . . n; n -number of classes . The global texture of anthracite is characterized as a RIS with main axes calculated as the weighted means of R , R and R for each class of this MAX INT MIN anthr
