Abstract

Lepidocrocite was identified associated with mica particles and in the clay fraction of two well-drained Ontario soils developed on a granite and a granite-gneiss. The occurrence of lepidocrocite is rare outside the tropics and there are no reports on its existence in well-drained soils.

Резюме

Резюме

Лепидокрокит был обнаружен в ассоциации с частицами слюды и в глинистых фракциях двух хорошо дренированных разновидностях почв из Онтарио, развитых на граните и гранито-гнейсе. Лепидокрокит редко встречается вне тропиков, и до сих пор не было сообщений о его существовании в хорошо дренированных почвах.

Kurzreferat

Kurzreferat

Es wurde gefunden,daß Lepidokrokit mit Glimmerteilchen verbunden ist und in den Tonfraktionen von zwei gut entwässerten Ontarioerden, auf einem Granit und Granitgneis entwickelt, vorkommt. Das Vorkommen von Lepidokrokit außerhalb der Tropen ist selten und es gibt keine Berichte über seine Existenz in gut entwässerten Erden.

Résumé

Résumé

La lepidocrocite a été identifiée associée avec des particules de mica et dans les fractions argileuses de deux sols bien drainés d’ Ontario, développés sur un granite et un granite-gneiss. On trouve rarement la lepidocrocite en dehors des tropiques et il n'y a pas de rapport de son existence dans des sols bien drainés.
