Description
Summary:	It is widely accepted the term Garnierite to designate nickelous minerals with triohedral claycrystalline structure of the type 1: 1 and 2: 1. In the same sense, although less known, is also used the term kerolite. However, in these denominations, from the mineralogic point of view, there is no taxative concretion. In nature, to these two terms correspond generally mechanical admixtures of trioctahedral phases of serpentinic and talcous types and, sometimes, intra-stratified phases. This situation is confronted with experimental results of hidrothermic transformations of kaolinite in nickelous media, carried out by the author, by which it was possible to synthesize the phases mentioned above in conditions of controlled pressure, temperature and concentration. The experimental results are discussed and compared to similar natural phases described in several publications.
