Morphological changes occurring in naturally weathered micas in seven residual soils from Ontario were studied. Splitting, exfoliation of the (100) planes, surface coats, filling of spaces with soil material as well as cracking and crumbling of (001) surfaces were the main morphological changes found to be taking place during natural weathering of mica particles. The significance of the observed feature in relation to the general theory of mica weathering is discussed.

Резюме

Резюме

Изучались морфологические изменения,наблюдающиеся в естественно выветренных слюдах в семи образцах элювия,отобранных в Онтарио. Было обнаружено,что расщепление,расслаивание плоскостей/100/,поверхностные покровы,заполняющие промежутки почвенным материалом,также как растрескивание и смятие поверхностей/001/ были главными морфологическими изменениями,происшедшими в период естественного выветривания частиц слюды. Обсуждается значение выявленных особенностей для общей теории выветривания слюды.

Résumé

Résumé

Les changements morphologiques survenant dans des micas naturellement altérés à l'air dans sept sols résiduels d'Ontario ont été étudiés. La fendaison et 1'exfoliation des plans(100), l'apparition de couches sur les surfaces, le remplissage d'espace de matière provenant du sol, ainsi que le craquement et l’émiettement des surfaces(001) étaient les principaux changements morphologiques survenant pendant l'altération naturelle des particules de mica à l'air. La signification de cette observation est discutée en relation avec la théorie générale de l'altération du mica.
