Scientific Activities
In 1927 , Yuli Hezeman defended his thesis in the specialty "geology" at the Hanover Higher Technical School . The topic of the thesis is " Devonian Harz iron ore deposits ". In the same year he began his active work as a geologist in Prussia Geological Administration of Berlin . His specialization is the mapping of ancient glacial deposits of the Quaternary period , and the topic of scientific work, which has become the main research task, is the development of methods for studying erratic boulders for paleogeographic purposes (identifying the stages and directions of movements of ancient glaciers and identifying regions of rejection of coarse rocks in Scandinavia .
In 1959 , Julius Hezemann was appointed head of the Geological Survey of North Rhine-Westphalia in Krefeld , where he worked until retirement in 1966 . Since 1961 , holds the position of professor at the University of Cologne .
Hezemann Formula
"Hezaman's formula" is a four-digit number indicating the percentage of erratic boulders of the geological outcrop studied, brought by an ancient glacier from four regions of Fennoscandia , isolated by a scientist in the process of research of Quaternary sediments of Western Europe . Hezeman divided the whole of Fennoscandia into 4 zones characterized by a certain set of erratic boulders, characteristic only of this zone. Zone I - Aland Islands , Finland , Northern Sweden and the Gulf of Bothnia ; Zone II - Middle Sweden, the region of the city of Stockholm and the middle part of the Baltic Sea ; Zone III - the southern part of Sweden and the Baltic Sea (including the island of Bornholm ); zone IV - Norway . For example, the number 7210 means that 70% of the guiding boulders are from zone I; 20% from zone II; 10% from zone III and 0% from zone IX.
This formula, later improved by German geologist Gerd Lüttig and Dutch scientists, is still used today and about 400 outcrops with erratic boulders and precise geo-coordinate reference have been studied in Western Europe.
