The Pollen Analyses of the Pleistocene Sediments from the Horjul Yalley

Abstract

The origin of the Horjul valley has been brought by scholars into connection with the tectonics of the Ljubljana Moor (Rakovec, 1946, 1956). The sediments that had been deposited in this valley may therefore help us in our efforts to solve the problems round the Ljubljana Moor.As early as in 1895, during drillings that were made at that time in this area, the peat was established among the sediments in the Horjul valley; in the years 1960 and 1961, during the regulation works in the valley, the peat was disco[1]vered in several places in a comparatively broad profile. Because of this discovery research was started in the valley by means of hand drilling in order to establish by way of pollen analyses the time of the sinking in of the valley and to find the correlation to the tectonics of the Ljubljana Moor. The approximate position of the drilling hole is 1410 19’ E and 46:0 1’ N; its altitude above the sea level 332'm.
