The use of heavy mineral content in Weichselian drift units as a stratigraphic tool has been investigated. A total of 26 heavy mineral analyses of representative samples frorn the four Weichselian kineto­stratigraphic units in eastern Denmark are presented with data on both non-opaque and opaque mineral content. The heavy mineral content frorn inferred source areas has been deduced, partly from published data and partly from studies carried out by the author. The data indicate that heavy mineral analyses cannot be used as a general stratigraphic tool. However, the heavy mineral distribution indicates the occurrence of two distinct Weichselian heavy mineral provinces, a northern and a southern. The reasons why clast petrography studies may supply more reliable stratigraphic information are discussed.
