Zusammenfassung:
This Technical Report presents data from a solaroptical spectral investigation in the area of the
Rammelsberg non-ferrous metal mine in the Harz Mountains near the city of Goslar. The investigation
refers to the local communion stone quarry (“Kommunionssteinbruch”) above the former mining area. As
this is a nature conservation zone, all measurements were carried out in-situ without any physical
sampling action. The field measurements were carried out in June 2019 in cooperation with Bergbau
Goslar GmbH and the German Research Centre for Geosciences (GFZ). The data were collected within the
research project ReMon (Remote Monitoring of Tailings Using Satellites and Drones, https://www.gfzpotsdam.
de/en/section/remote-sensing-and-geoinformatics/projects/remon/) which aims at developing
a prototypical monitoring system for mine tailings by using different sensors scaling from satellite- to
drone-based. The data were analysed in the unpublished B.Sc. thesis of Constantin Hildebrand
(Hildebrand, 2019). Sixteen different surface materials were determined and examined on-site. Point and
imaging hyperspectral data were acquired (with the spectroradiometer PSR+ 3500 operating in the range
of 350 - 2500 nm and with the Cubert FireflEYEUHD-185 hyperspectral camera with a range of 450 - 950
nm, respectively), both data sets are presented as spectral libraries. Chemical analyses of the samples
were performed by using Laser-Induced Breakdown Spectroscopy (LIBS). LIBS data were collected using a
handheld LIBS analyzer, the SciAps Z-300. In this report the different in-situ measurements are presented
for each of the sixteen samples. Detailed information about the analysed material, the area of spectral
sampling and geochemical analyses are explained in this report and can also be found in the additional
Excel® sheet provided with the data.
