Study of a deformed quay wall, Ruse City

Engineering Geological Expertise

An engineering geological and geophysical study of a vertical sheet pile quay wall on the Danube River was carried out. The quay wall is depreciated and a new structure has to be built. The IBG scientists in cooperation with Prof. Dr. Yordan Evlogiev have compiled a report on the engineering geological conditions and analysis of the present state of the deformed wall.

Dating of skarn Ca-garnets

Application of isotope-geochemical LA-ICP-MS and ID-TIMS methods

The combined application of isotope-geochemical LA-ICP-MS (Laser Ablation Inductively Coupled Mass Spectrometry) and ID-TIMS (Isotope-Dilution-Thermal Ionization Mass Spectrometry) techniques with field, microscopic and mineralogical research allowed for the first time in Bulgaria to date skarn Ca-garnets from different metallogenic zones. New U-Pb LA-ICP-MS garnet standards have been introduced, ...

The evolutionary dynamics of Lake Ohrid

Deep drilling in Europe's oldest and most species-rich lake provides new insights into evolution

The older and more stable an ecosystem is, the longer lived its species and the more stable the species communities are. An international research team led by the Justus Liebig University Giessen and the University of Cologne gained these new insights into evolution by drilling deep into the sediments of Lake Ohrid. The 1.4 million year old lake on the border between Albania and Northern Macedonia ...

Sampling of sediments from the Danube River basin

Project DTP2-093-2.1 – SIMONA

In September 2020, a team from Geological Institute conducted a testing of sediments (bottom, suspended matter and active floodplains) in four river stations in the Danube River Basin as a part of the Southern Danube test area. The study is implemented in the work program of the project "Information system, monitoring and evaluation of sediment quality to support transnational cooperation for join ...
