Provenance of mafic outcrops and igneous clasts in Kobuk-Koyukuk sub-basin conglomerates and basin formation from sample geochemistry
Agata Kubiak (BSc student)

Pillow basalt, possible correlative of the Angayucham ophiolite.

The pillow basalt of the Angayucham ophiolite outcrops in the eastern Koyukuk basin. Geochemical samples were collected to confirm the tectonic setting of these rocks and to compare them to analyses of the Angayucham ophiolite to the west. These normal mid-ocean ridge basalts document ocean closure during Brookian Orogenesis.
