Hundred years of loess research in Zemun (Serbia): From an expert note to new challenges in geology

In remembrance of the 100 th anniversary of the arrival of geologist and university professor Vladimir Laskarev in Serbia and the beginning of scientific research of loess sections in Zemun, the author's intention is to point out the importance of knowledge of geological history and tradition, but also the actual nature of the study of loess-paleosol deposits. This is especially important at the time when numerous projects and teams of researchers in Serbia and the world are dealing with this issue. Today as well as in Laskarev's time, they all have the same task: to qualitatively and quantitatively explain natural processes and their consequences, and to point out significant oscillations in temperature and climatic fluctuations during the Pleistocene.
