The conceptual 3D geological model of the uranium deposit Rozna is closely connected with the 3D geological model of the entire deposit. It shows a simplified situation of uranium mineralization in the Rožná deposit. Uranium ore deposits are shown in zones SY1, SY2, SY3, SY4, SY7 and SY11 in three metallicity categories. The model makes it possible to display individual zones without uranium ore, separately individual bodies according to the category of metallurgy, ore bodies of individual zones and combin...

The detailed 3D structural geological model of the Hrádek candidate site summarizes the existing geological knowledge at one of the nine sites considered for the planned deep repository of high-level radioactive waste in the Czech Republic. The area of interest is characterized by simple geological structure that includes two lithotectonic units. Metamorphic rocks are of Prevariscan protolith, which was nevertheless significantly reworked during Variscan orogeny between c. 340 – 320 Ma. Magmatic rocks ar...

Photogrammetric 3D model shows a part of westward tunnel Z3-XX located on the 20th floor of the Rožná uranium mine roughly 1000 m below ground level. This illustrative model is a part of a much larger collection of nearly 200 similar models created between years 2018 - 2019 as a part of project "Obtaining data from deep horizons of Rožná mine" funded by the Radioactive waste repository authority of the Czech Republic (SÚRAO). These models have been used to determine actual state and frequency of brittle fr...

Photogrammetric 3D model shows part of the Jizerka stream in the Jizerka village. This area is famous for historical and current illegal sapphire mining. This area has been historically famous for precious stones (sapphire and izerine) which makes it still attractive for individual searchers. Currently any mining activities are strictly forbidden. 3D model enabled to study past systematic mining in this area, including estimation of number of stones obtained.

Photogrammetric 3D model of the northern bank of the Nechranice dam in the Czech Republic, composed of uncemented sandstone, intercalated with clay, caustobiolites and volcanic or volcanoclastic material. The model captures the normal fault structure separating the sandstone part (left side of the model) and the sandstone with clay and caustobiolite inserts (right side of the model), including a recent landslide. The imaging of the area took place in the summer of 2018, when during the dry season the water...
