Factor analysis applied to distribution of elements in western Turkey

This paper examines the results of R-mode factor analysis performed on four radionuclides and two elements data from a geochemical survey from western Turkey. Sediment and soil samples numbering 321 were collected along the Gediz river and analysed for 238eU, 232eTh, 40K, 226Ra, Mg and Pb. Two factors in soil and sediment, which account for 59% and 56% of the total variance, respectively, were extracted and named as geological structure and volcano.
