Abstract

Allophane was found to predominate in the soil derived from volcanic ash in the Colombian Andes. The allophane is transformed into halloysite. The soils of the superhumid tropical forests derived from marine deposits are high in kaolinite and low in gibbsite. Other clay minerals found in Colombian soils include vermiculite, montmorillonite, chlorite, and illite.
