TABLE 2. Summary of correlations and tectonic linkages for the Circum-North Pacific - Continued. Kamchatka volcanic and sedimentary basin, East Kamchatka volcanic belt, Eastern Sakhalin sedimentary basin, and the West Kamchatka sedimentary basin. . .-.
9! TABLE ectonic environment of Proterozoic and Phanerozoic metallogenic belts in the Russian Far East, Alaska, and the Canadian Cordillera. Refer to Figures L-1 8 for location of metallogenic belts. For each time interval (time-stage) in the metallogenic-tectonic model, the metallogenic belts are listed in a clockwise order, according to similar tectonic environments, starting with the area of the Russian Southeast and ending with the area of the southern Canadian Cordillera. [Environment refers to metallogenic-tectonic environment of host rocks as defined and described here. Time scale is from Palmer (1983). Metallogenic belts are defined and adapted from Nokleberg and others (1997a, b, 1998b) and as modified herein. Abbreviations given for metallogenic belts as depicted on generalized maps of metallogenic belts and host rocks (figures 2-1 8) and on metallogenic-tectonic model for Devonian through Present (Figures 19-32).] Metallogenic Belt (Abbreviation) I PROTEROZOIC METALLOGENIC BELTS (2500 TO 570 Ma) (Figures 2,3) Major Mineral Deposits Types.

Mesoproterozoic to Neoproterozoic incipient rifting of passive continental margin (sediment-hosted Cu deposits). Lantarsky- Gabbro and anorthosite plutons, Mesoproterozoic rifting of passive continental margin of North Asian Craton and Dzhugdzhur (LD) and alkali granites intruding intrusion of gabbro and anorthosite plutons, relatively younger, Rapakivi-type North Asian Craton. alkalic granite.

Sedimentation along Proterozoic passive continental margin (ironstone deposits). Verkhoyansk fold belt, North Asian Craton Margin. Neoproterozoic incipient rifting of passive continental margin. Omolon (OM) Ironstone (Superior Fe). Marine sedimentation. Sedimentation along Paleoproterozoic passive continental margin. (Verkhny-Omolon)) Omolon terrane. Terrane interpreted as a rifled fragment of North Asian Craton. Kilbuck (KI) Ironstone (Superior Fe). Marine sedimentation. Sedimentation along Paleoproterozoic passive continental margin. (Canyon Creek) Kilbuck terrane (pre-rifting). Rifted fragment of North Asian Craton. Metallogenic Belts Formed During Proterozoic Sedimentation, Rifting, and Hydrothermal Activity Along North American Craton or Craton Margin Sinuk River (SR) Stratiform massive sulfide-barite. Marine volcanism. Interpreted as forming during marine volcanogenic rifting(?) of the North (Aurora Creek, Nelson, Rocky Mountain Creek, Quarry) Stratabound Fe and Mn (American, Bqr, Cub, Monarch) Seward terrane.
