From the Nutzotin Mountains along the Alaska-Yukon border to southeast Alaska, Wrangellia forms a thin northwest- to southeast-trending belt in the southwest corner of Yukon. This belt is separated from several small discontinuous exposures of Wrangellia to the southwest by rocks of the Alexander Terrane.
The Seward Peninsula of northwestern Alaska is part of the Arctic Alaska-Chukotka terrane, a crustal fragment exotic to western Laurentia with an uncertain origin and pre-Mesozoic evolution.

The Yukon–Tanana Terrane (YTT) is a tectonic terrane that extends from central Alaska through central Yukon and into northern British Columbia, Canada and Southeast Alaska, USA.
Extending over km, the YTT is the largest tectonostratigraphic terrane in the northern North American Cordillera. Assemblage 2 more strongly resembles the Chulitna Terrane of Alaska rather than either the Windy or McKinley terranes as originally defined.
Assemblage 3 resembles part of McKinley Terrane, as well as the Aurora Peak and Pingston terranes. These terrane re-assignments have implications for the area¿s mineral potential.
All of the major ophiolitic terranes (Angayucham, Tozitna, Innoko, Seventymile, and Goodnews terranes) in the northern and central Alaska belong to the Tethyan-type' of Moores () and were obducted onto Paleozoic and Proterozoic continental and continental margin terranes in Mesozoic time.
Thirty‐six samples from plutons of the Ruby batholith of central Alaska were collected and analyzed for 22 trace elements, and many were analyzed for the isotopic compositions of Sr, Nd, O, and Pb in order to delimit the processes that produced the diversity of granodioritic to granitic compositions, to deduce the nature of the source of magmas at about Ma, and to characterize the deep Cited by: Thirty‐six samples from plutons of the Ruby batholith of central Alaska were collected and analyzed for 22 trace elements, and many were analyzed for the isotopic compositions of Sr, Nd, O, and Pb in Cited by: OFF Ophiolitic terrane bordering the Yukon-Koyukuk basin, Alaska, by Patton, W.W., Jr., OF G Ophiolitic terranes of east-central and southwestern Alaska byCited by: 6.
