PEDOTUBULES: THEIR DEFINITION, CLASSIFICATION, AND INTERPRETATION

Abstract

Summary The term pedotubules is proposed for a group of pedological features which have a tubular external form and which are distinguished from cutans (Brewer, 1960 a ) by their complex internal composition and fabric. Pedotubules are classified according to their internal fabric and composition, details of external form, distinctness, and by a comparison of their fabric and composition with that of the horizons of the soil profile. Their general morphology suggests their origin as voids caused by faunal and floral (root) activity which have been filled, or partially filled, with soil material. Since little is known of the details of the effects of faunal activity on soil materials, such interpretations are tentative.
