Seiland Island is divided administratively into 3 municipalities (kommuner): Alta, Hammerfest and Kvalsund. For localities in the Hammerfest part of Seiland island see: http://www.mindat.org/loc-212041.html
Note on the zircon localities in the nepheline syenite pegmatites in the southern part of Seiland Island: The locality Store Kufjord is the largest and most well-known locality but there are other, smaller localities.
NB: A large part of Seiland Island is now protected by law as a National Park. For details see FOR-2006-12-08-1364, link listed above. NO mineral collecting is allowed inside the park.

24 valid minerals.
This information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This data will improve over time as more accurate maps and data sets are added.
|Cambrian-Ordovician443.8 - 541 Ma||Cambrian-Ordovician plutonic rocks|
Deep-seated to high-level intrusions are included. Many charnockites, anorthosites, and large ophiolites, classified as plutons, are distinguished in the database using the SIGNIF item. Ophiolites were classified as plutons, even where remnants may be extrusive and/or sedimentary.
|Cambrian - Neoproterozoic485.4 - 1000 Ma||Igneous: intrusive; Intrusive: gabbroic|
