The reported study aimed to identify low-pH areas at the Sokolov lignite open pit, using space borne and
ground-based spectroradiometry. Mineral spectroradiometry, from spaceborne sensors and ground
measurements, represents an alternative to conventional methods and provides an efficient way to
characterise mines and assess the potential for acid mine drainage (AMD) discharge. The mineralogical
composition of sediments is primarily a determinant of their inherent reflectance properties. However,
additional parameters such as organic matter content and trace element abundance are also known to have
an influence on soil and sediment reflectance. As long as the effects of sediment composition, organic matter
content and trace element abundance can be spectrally distinguished, it might be possible to map these
variables at synoptic scales using remotely sensed data. In mining environments (still active and abandoned
mines), mapping the spatial distribution of mineral composition and the additional soil/rock parameters
provide unique constraints on both the origin of the allochthonous material as well as the geochemical
processes that occur at the site. Field and laboratory spectra of more than 250 surface rock samples at the
Sokolov open pit mine, Czech Republic, were measured using an analytical spectral device (ASD)
spectroradiometer during field investigations in 2007 and 2008. Additional in situ and laboratory pH
measurements, X-ray powder diffraction (XRD) analyses and other laboratory methods allowing a
quantitative diagnostic of trace elements, sulphur and organic matter were conducted on the selected field
samples. Firstly, the effect of the mineralogy and the geochemical variables, e.g. organic matter and AMD
mineral indicators, on the rock reflectance property was studied and then the feasibility of resolving some of
these effects with satellite imagery, e.g. advanced spaceborne thermal emission and reflection radiometer
(ASTER) was tested.
