Journal Article
Published: 01 February 1939
American Mineralogist (1939) 24 (2): 123–129.
...Robert W. Webb Abstract An occurrence of a purple mica is described, an analysis of the mineral presented, and the conclusion reached that it is identical with alurgite, described previously only from St. Marcel, Piedmont, Italy. It is contended that alurgite is sufficiently different in physical...

... minerals are bixbyite, braunite and hematite of two generations and jacobsite associated with spessartite and alurgite. In the epigenetic veins cutting across bedded deposits and in the wall rocks surrounding them, hollandite, micaceous hematite, cryptomelane and pyrolusite are present associated...
Journal Article

American Mineralogist (1955) 40 (11-12): 983–995.
...E. Wm. Heinrich; A. A. Levinson Abstract X -ray studies on the high-silica sericites indicate that alurgite crystallizes as the 3T and 2M polymorphs, that mariposite crystallizes as the 2M and 1M polymorphs, and that material called phengite (including sericite) has crystallized as 3T, 2M and 1M...

..., often associated with Mn-bearing phengitic mica (“alurgite”), ± Mn-rich carbonates and other minor phases. All manganese deposits show similar lithostratigraphic features. Rounded or flattened lenses of massive braunite represent the ore deposit in the manganiferous layers. These lenses are 1 cm...
