From "CSIRO research for Australia" (1962) pdf page 46:
"Within the grounds of the University of Melbourne are two small C.S.I.R.O. Sections which are primarily occupied in serving the needs of the mining industry. They are called the Mineragraphic Investigations and Ore-Dressing Sections.

Mineragraphy is the study of ore materials in polished surfaces by microscopic, spectrographic, X-ray and other techniques. C.S.I.R.O.'s entry into this field dates back to 1927, the second year of its existence, when Dr. F. L. Stillwell was appointed to initiate the work. Mineragraphy has been applied to a very wide range of mining and oredressing problems. It has been used, for example, to get information about the association of different minerals in ores and to detect losses of valuable minerals in mill wastes and tailings and furnace products. Jt has also been used in conjunction with petrological investigations to study the gangue minerals and rocks associated with ore-bodies and problems of ore genesis, and the composition of economic beach sands. The content of mine and other dusts has been studied in order to assess their possible hazards to health.

Mineragraphic, mineralogical and petrological techniques have also been applied to scientific problems not associated with mining. They have, for example, been used to study the drift of sands on the ocean floor; the "opal phytoliths" which are formed in plant tissues and cause wear of sheep's teeth; and the mysterious objects of impure silica glass called "tektites" which come from outer space. Many of the Section's substantial contributions to mineragraphy have been drawn on for the compilation of a standard text called "The Texture of Ore Minerals and Their Significance" by Dr. A. B. Edwards, who was Officer-in-Charge of the Section from 1953 to 1960."
