Abstract
X-ray microscopy allows the direct visualization of soil colloids in water. In
combination with tomographie techniques it is possible to visualize the three dimensional
distribution of the linear absorption coefficient of soil colloids and to investigate the surface
amount and spatial arrangement of the particles. First experiments of Nontronite particles
from the XM-1 are presented.
