These hazardous locations need to be further studied using
field and laboratory analysis in order to investigate their risk
degree for construction purposes. Geotechnical soil analysis
such as the free-swell test, colloid content, plasticity index
and shrinkage limit is essential for a direct determination of
the swelling potential of these clays. It is recommended to
geotechnically analyze the samples obtained from the field
and determine their swelling properties and also analyze using
X-ray diffraction methods. In addition it is suggested to
acquire hyperspectral data to be used for accurate mapping
of clay minerals and alteration zones.
