Figure 17. Generalized map of major Middle and Late Devonian metallogenic and Mississippian belts and terranes for Alaska, Canadian Cordillera, and adjacent offshore areas. Refer to text for description of metallogenic belts. Adapted from Nokleberg and others (1 997b, 1998). Refer to figure 3 for explanation. (1) sporadic occurrences of marine and continental volcanic and associated rocks and subduction-related -tic r d s in tbe southern part of the craton margin (NSV); (2) units which overlie parts of the Okhotsk (OK), Akekova (w, Omobr~ (OM] cratonal terranes; (3) the Oloy (OL) and Yarakvaam (YA) island-arc terranes; and (4) the Beryozovka (BE) turhi&t-kh tmttne. Associated with this arc was the subduction of the older part of the Galarn (GL) accretionary-wedge terranc alosg tbe d the North Asian Craton and Craton Margin (NSC, NSV), and subduction of the Angayucham and ancestral Pdik- dvng the margin of the North American Craton Margin (NAM). Forming in part of the North Asian Craton M- h WW ihe Omolon terrane was rifted, was the Kedon metallogenic belt which contains deposits related to felsic to adc tnud V- Qr to granitic magmatism in the Kedon arc. In the Alaska and the Canadian Cordillera, the arc is preserved today in sporadic occurrences crf mb~ uakmic and associated rocks and shallow- to deep-level subduction-related granitic rocks in various parts of the Arctic AI& @A), Coldfoot (CO), Ruby (RB), Seward (SD), Yukon-Tanana (YT), and Kootenay (KO) terranes. Occurring in this mc, now pnxu~d in various continental-margin terranes, were the Arctic (AT), Brooks Range (BR), Dawson (DA), franc^ b k (FR), ~ Shuswap (KS), and Tracy (TR) metallogenic belts, which contain deposits related to felsic to mafic marine voitanism or to granitic magmatism. The Devonian arc is interpreted as extending discontinuously from Arctic Alaska to wrt.h Californlr (Rubin and others, 199 1 ; Mortensen, 1992; Smith and Gehrels, 1992; Nokleberg and others, 1994a; Plafker md B-, 1994). (3) In the late Late Devonian, rifting of the North Asian and North American Cratons and Cram P&IW ocwu~ed. Derived from the North Asian Craton (NSC) and Craton Margin (NSV) were the Kotelnyi (KT), Omukvka (OV), hhlp (PR), Nixon Fork-Dillinger-Mystic (NX, DL, MY), Viliga (VL), and Zolotogorskiy (ZL) passive contincod-mugin tat-we, tb. Avekova (AK), Kilbuck-Idono (KI), Okhotsk (OK), and Omolon (OM) cratonal terranes. Derived from he Pevarhtn ~WUEUIU margin arc which formed along the margins of the North Asian Craton Margin were the Beryozovka (BE), OLay OL), d Yarakvaam (YA) terranes (fig. 18). The newly-created terranes migrated into the Angayucham Ocean. Derived from the ~ onh American Craton Margin (NAM) were the Kootenay (KO) and Yukon-Tanana (YT) passive continental-mugm tmw. The .: following metallogenic belts, which contain massive sulfide, carbonatite-related Nb, Ta, and REE, or related depolEi&, Bararcd during rifting: Berezovka River (BE); Cathedral (CA), Dempster (DE), Finlayson Lake (FL); Gataga (GA), hgtnilss {&), Li&, ' (LI), older part of Mystic (MY), Northern Cordillera (NCO), Macmillan Pass (MP), Robb Lake (RL), Selemyakh River (m), ' Sette-Daban (SD), Southern Rocky Mountain (SRM), Tomrnot River (TO), Urulh~n and Sudar Rivers (URQ, md Yarkkdm . .
