.... Stereographic plotting, normally required in using both the Fedorow method and the standard five-axis method, is eliminated. The method is particularly useful for routine compositional determination of plagioclase from volcanic, hypabyssal, and epizonal and mesozonal plutonic environments, in which marked...

... by means of convergence methods. Fig. 4. Construction to solve the problem of two tilts. A rapid approximate solution of the problem of two tilts, which also serves as a check on the graphical method, may be accomplished with the Fedorow universal stage mounted on the microscope stage...

... ; Brun 1911 ). On the role of minerals in explaining geological phenomena, he said, If petrography wants to make progress, it must return to the methods advocated by Fouqué, namely the study of minerals in isolation. But this work is difficult and we settle for cruder analyses. So, science marks...

.... van Biljon; Snyman, 1997 ). During a sabbatical at the ETH, Zürich in 1932, Scholz further honed his skills, studying igneous petrology with P. Niggli, the Fedorow method under Burri and ore microscopy with Parker, all famous men in their day ( Snyman, 1997 ). This newly acquired knowledge...
