Abteilung Erkundung

Wertschöpfungskette Rohstoffe - Erkundung

Die Abteilung Erkundung entwickelt neue und effiziente Technologien für die Erkundung von mineralischen Rohstoffen. Ihre Forschungsschwerpunkte sind: der Einsatz von unbemannten Luftfahrzeugen in Kombination mit unterschiedlichen Sensoren und Erkundungsmethoden, die multi- und hyperspektrale Fernerkundung, die strukturgeologische Lagerstättenanalyse, die tektonische Geomorphologie sowie die Lithogeochemie und deren Korrelation mit skalenübergreifenden In-situ-Daten. Außerdem werden die laserinduzierte Fluoreszenz- und Lumineszenzspektroskopie von Mineralen erforscht.

Geological Remote Sensing

In geological remote sensing, scientists use contactless measurement ­techno­logies to digitally record the specific characteristics of the earth´s surface. These can either be spectral characteristics of minerals and vegetation or the morphometric expression of mineral deposits. The aim is to capture their spatial distribution and expansion. The Departments´s strength is combining multi-scale data and multi-source data into a composite model to assess the potential of natural mineral deposits.

Laser-Induced Fluorescence Spectroscopy

In Laser-Induced Fluorescence spectroscopy (LIF), a laser stimulates a sample surface, which results in a specific glow. This spectroscopic measurement technique is used to characterize materials as well as their constitutive componen­ts fast and precise. The Exploration Department focuses on critical raw materials in natural rock such as rare earth elements, vanadium, chromium, ­tungs­ten or molybdenum.

Mineral Exploration with Drones

The Exploration Department uses Unmanned Aerial Systems (UAS), also known as drones, to develop less invasive and high-resolution methods for the exploration of mineral and metalliferous raw materials. The methods utilized include aerial photogrammetry, multi- and hyperspectral remote sensing, as well as geophysical methods. The scientists use the data, obtained from drone flights, in geological remote sensing and 3-D modeling to understand the structural control and pathways of mineralized fluids.

Geophysical Exploration of Mineral Resources in the Erzgebirge

Testing and developing modern techniques for the delineation of mineral resources to depths reaching 500 ­meters is the main task of this project. Scientists combine geological data with airborne geophysical measurements. Current exploration focuses on an area of approximately 100 square kilo­meters around the city of Geyer in the Erzgebirge, a low mountain range located in Eastern Germany. The ­information will ultimately be included in a high resolution, three-dimensional geological model.
