The Mindat entry for Amianthus lists it as a synonym of brucite. This is incorrect. Amianthus is either a serpentine or amphibole with fibrous structure (American Mineralogist, v. 63, pp.1023, 1978, see also Index Alphabetique de Nomenclature Mineralogique by Aballain, 1968). I believe the Mindat entry was referring to Amianthöide Magnestite which was listed as Fe-rich brucite in Dana's Mineralogy 6th edition. http://www.mindat.org/forum.php?read,7,266914,266914#msg-266914 Sun, 26 May 2013 04:21:51 +0000 Phorum 5.2.15a http://www.mindat.org/forum.php?read,7,266914,271669#msg-271669 http://www.mindat.org/forum.php?read,7,266914,271669#msg-271669
The original ref. [Pierce (1818), American Journal of Science: 1: 54.] probably needs to be checked.]]> Uwe Kolitsch Mistakes and Errors Fri, 21 Sep 2012 20:10:29 +0000 http://www.mindat.org/forum.php?read,7,266914,266914#msg-266914 http://www.mindat.org/forum.php?read,7,266914,266914#msg-266914
