THERMAL/IR IN GEOLOGY

It is easy to separate areas with different radiant temperatures, but it is very difficult to make definite statements about the properties of the surface materials using only their temperatures or temperature variations. Meteorological conditions mainly determine the actual radiant temperature, whereas the thermal properties of soil and rocks cause only minor variations. Increasing porosity causes lower thermal inertia and lower damping depths, resulting in higher temperature variations at the surface. Increasing water content generally augments the thermal inertia and the damping depths, and is responsible for smaller temperature variations. The mineralogy is only important in water-saturated soils and rocks or consolidated rocks with a low porosity. Therefore it is not possible to determine one parameter, e.g., water content, without the knowledge of at least a few others, e.g., porosity and weather. /Author/
