As stated in the "Note added in proof" to The First List of Additions and Corrections to the Glossary of Mineral Species 7th Edition (1995), a major revision of the classification and nomenclature of the Amphibole Group has been published in several mineralogical journals.
The classification of the Amphibole Group has been revised by a subcommittee of the Commission on New Minerals and Mineral Names (CNMMN) of the International Mineralogical Association (IMA).

These can be structurally divided into two main groups, the serpentine and amphibole groups
. The serpentine fibers (mainly chrysotile) are long and flexible.
