Magmatic rocks of post-Late Eocene magmatic formation are widespread in the Sava segment of SavaVardar suture zone and adjoin areas. The rocks formed as a response to transpressional-transtensional tectonic activity preceded by the Cretaceous-Eocene compression of the Internal Dinarides and Tisia Unit as fragments of Eurasian continental lithospher...

Deicing reagents have an impact on the environment. The composition of the deicing reagents used in Moscow has undergone certain changes. However, the main components of deicing reagents were chlorides, including calcium chloride and (or) sodium chloride. We also conducted research on the effects of sodium chloride and calcium chloride on some urba...
