Locally within the stope environs, the complexly deformed manganese andiron ores assume the attitude of a vertically plunging cylindroidal fold in which ribbeite has a preferential association with carbonate-silicate facies within the manganese ores. The lenses are derived by tectonic transposition and boudinaging of the original sedimentary protore layering. The area containing ribbeite measured only ca. 40 cm across as exposed on the stope back. Ribbeite can be regarded as a scarce mineral. The transposed layering is transgressed by an abundance of veinlets of a proposed new manganese hydroxy-carbonate that clearly postdate the major tectonism but are themselves slightly deformed. Of interest also is the occurrence of manganosite as a constituent (to 5olo by volume) of some hausmannite-pyrochroite-barite-calcite layers within the Mn ores but not immediately associated with the ribbeite-alleghanyite layers. The manganosite is altering to pyrochroite and hausmannite and occurs as ragged emerald-green relicts up to 2 cm in diameter. The textural evidence strongly suggests that manganosite was a syngenetic precursor of the hausmannite ores.","National Museum of Natural History, Washington, D.C., USA, 163208.","Named in 1987 by Donald R. Peacor, Pete J. Dunn, S. C. Su, and J. Innes in honor of Paul Hubert Ribbe [2 April 1935 Bristol, Connecticut, USA - 24 June 2017 Virginia, USA], professor of mineralogy at Virginia Polytechnic Institute and State University, Blacksburg, Virginia, USA and investigator of crystal structures, particularly those of the feldspar group. The publication of the new species commented: \"We have named this new species ribbeite in honor of Dr. Paul H. Ribbe in recognition of his many contributions to mineralogy, both to the science through his research, and to the society of mineralogists, in part through his editorship of the Reviews in Mineralogy series of the Mineralogical Society of America. It is particularly appropriate that ribbeite is closely related to the humite group, to which he has made major contributions.\"","2025-08-11
