Formula:
(Ni,Al)3(Si,Al)2O5(OH)4
Colour:
Dark yellow-green
Hardness:
2½ - 3
Specific Gravity:
3.17
Crystal System:
Monoclinic
Name:
Originally named nimesite by Z. Maksimovic in 1972 but the name was not approved by the IMA due to its similarity to the similar mineral nimite. It was renamed by Maksimovic and David L. Bish in 1978 in honor of George William Brindley (19 June 1905, Stoke-on-Trent, England - 23 October 1983), Professor of Mineral Science, Pennsylvania State University, University Park, Pennsylvania, USA. He was an expert on clay minerals and won the 1970 Roebling Medal.
The nickel analogue of berthierine.
Kaolinite-Serpentine group.
1M plus 3A and 1A polytypes assumed.
