| Zusammenfassung |
| Landslides in tropical and sub-tropical regions are generally associated
with weathered rock profiles which often possess chemical and mineralogical
heterogeneities at material- and mineral-scales. Such heterogeneities reach
a climax by the occurrences of oxyhydroxide- and clay-rich zones. Weakness
and low permeability of these zones makes them ideal for the development of
slip zones along which landslides take place. This paper describes the
nature and distribution of chemical and mineralogical heterogeneities within
weathered profiles developed from felsic igneous rocks in Hong Kong. It sets
out the use of integrated geochemical and mineralogical studies to improve
understanding of the development of critical heterogeneities and hence to
predict their types and presence in a given weathered profile. |
