New data on composition of intrusive rocks from Shikotan island (Lesser Kuril Chain)
The article presents new petrologic and geochemical data on gabbroids from Shikotan Island (Lesser Kuril Chain). The results were compared with co-magmatic Late Cretaceous-Paleocene volcanics from the Zelenov Formation, as well as with the rocks from the
