Abstract

The work deals with the research task results about the transparent heavy minerals from the Napajedla surroundings loess exposures. The workt ries to solve the problems of the qualitative and quantitative representation of the individual specific types (orgroups) of the heavy minerals as well as mutual relations of the heavy minerals chosen from 6 size fractions : 0.04 till
0.05 mm, 0.05-0.063 mm, 0.063-0.10 mm, 0.10-0.16 mm, 0.16-0.20 and 0.20-0.25mm, which were allgained from 14 loess samples of 4 localities (therefore 84 fractions in all). Besides other relations ensuing from the detailed sieve analyses results, from the heavy minerals separations (from 2 g of the made-up grounds) are studied here and at the end the results of the special
analyses of 2 chosen grenat grains using the method of the electron microprobe analyzer (carried outin the laboratory of the Geological Central Institution in Prague) are mentioned.
