Characterisation and Engineering Properties of Natural Soils
L.D. Wesley University of Auckland, Auckland, New Zealand ABSTRACT: The
clay mineral allophane plays an important role in governing the characteristics of
certain clays of volcanic origin. These clays occur when non-crystalline parent ...

The chemistry of clay minerals
ALLOPHANE Allophane is a fine-grained amorphous material composed largely
of silica, alumina and water. It has both a glassy and an earthy appearance.
Material with this composition is clear to white in color; however, because of the ...

Principles of Soil Chemistry, Fourth Edition
The most important type of clay in this group is perhaps allophane. It is found
especially in volcanic ash soils. The name allophane was first introduced by
Stromeyer and Hausmann in 1861 for hydrous aluminosilicates occurring in
nature.

Clays and Clay Minerals of Japan
The high phosphate retention (307-402 mmole P per 100 g clay) and very low
ratio of CEC to phosphate retention (0065-0186) were considered to characterize
allophane. Wada (1959) studied the reaction of 1 M ammonium phosphate with ...

solution, Wada and Greenland (1970) succeeded in separating several types of
noncrystalline alumino-silicates, but these can only be considered allophane-like
constituents. They have not been detected in soils, hence the possibility exists ...
