|Hydrotalcite Group > Hydrotalcite Supergroup|
|Name:||Named in honor of John Leslie Jambor (1936-2010), Canadian mineralogist, Geological Survey of Canada, Ottawa and CANMET, Ottawa, (1960-1993), Professor of Mineralogy (1994-2000), University of Waterloo, Waterloo, Ontario, and coeditor of Canadian Mineralogist (1975-1977). Jambor is one of the most prolific investigators of Canadian type minerals, who described or participitated in the description of 31 new species.|
As part of the recent re-evaluation of the nomenclature of the hydrotalcite supergroup (Mills et al., 2012), jamborite was identified as a questionable species which needs further investigation. formula may be Ni2+6Ni3+2(OH)16S · 4H2O
