Science Blog: Portable XRF as an example of advanced on-site analysis methods in mineral exploration

Text:
Pertti Sarala, Research Professor, Docent, Ph.D., EurGeol

Recent methodological development has given new possibilities to determine the chemical and mineralogical composition of sample materials with accuracy and quicker than before. Advanced portable field techniques provide a cost-effective way to analyse several types of samples directly in the field and increase the number of methods to be used in exploration. These methods provide […]

Science Blog: LiDAR revolution in geoscience

Text:
Antti Ojala, Senior Scientist
Jukka-Pekka Palmu, Senior Researcher

The advent of LiDAR (Light Detection And Ranging) technology has enabled rapid documentation of geological and geomorphological characteristics and allowed significant advances in theories on these formations (e.g. Johnson et al., 2015). Previously detected mega-scale landforms, such as large drumlins and end moraine complexes, show up in LiDAR-based digital elevation models (DEM) in greater detail […]
