| Summary: | Herschel Island and the Yukon Coastal Plain are an important research area as they geographically lie at the northwestern limit of the Laurentide glaciation (Mackay,1959). Quaternary geological maps show that sedimentary deposits are found in the study area around Komakuk Beach, Herschel Island, Roland Bay and Kay Point. These were found to be predominantly fluvial and glacial. In this work, glaciated and nonglaciated areas are compared in order to improve the distinction between the two. Four parageneses were identified from three heavy mineral provinces by means of heavy mineral analyses. The minerals from a proximal sedimentsource are predominant in the British Mountains. The greenschist fragments,zoisite and epidote originate from stone of the greenshist facies of the Neruopuk Formation. The clinopyroxenes derive from the basalt areas at the border to Alaska. In the region east of the Mackenzie River, in the vicinity of Inuvik, larger deposits of dolomitestone are found, from which dolomites and ... : Supplement to: Hohberg, Stefanie (2017): Sedimentherkunft an der Yukon Küste, Kanada - Hinweise aus Schwermineralen und kornmorphoskopischen Untersuchungen.
