One of the most important aspects of the interpretation of geochemical data is the choice ofanomaleus values from among these data. Disticuvely anomalous values are readily diseriminated, because they are characterized by statistical methods. Applications of these methods are described in the present paper.
During the last few decades coal chemistry and coal petrology have developed as special fields of research, of equal importance from both the scientific and practical viewpoints. Until the nineteen twenties coal chemists used to examine coal as a whole. However, after coal petrographers had. discovered tha…
