“…The project aims to provide critical information on bedrock geology and geophysics, tectonics, major metalliferous mineral resources, metallogenic patterns, and crustal origin and evolution of mineralizing systems for these regions. Published major companion studies for the project are: (1) a report on the metallogenesis of mainland Alaska and northeastern Russia (Nokleberg et al, 1993); (2) a tectonostratigraphic terrane map of the Circum-North Paciµc at 1:5 000 000 scale with a detailed explana- tion of map units and stratigraphic columns (Nokleberg et al, 1994a); (3) a tectonostratigraphic terrane map of Alaska at 1:2 500 000 scale (Nokleberg et al, 1994b); (4) a summary terrane map of the Circum-North Paciµc at 1:10 000 000 scale (Nokleberg et al, 1997a); (5) detailed tables of mineral deposits and placer districts for the Russian Far East, Alaska, and the Canadian Cordillera in paper format and in CD-ROM format (Nokleberg et al, 1997b); (6) a GIS presentation of a summary terrane map, mineral deposit maps, and metallogenic belt maps of the Russian Far East, Alaska, and the Canadian Cordillera (Nokleberg et al, 1998); and (7) a study of the Phanerozoic tectonic evolution of the Circum-North Paciµc (Nokleberg et al, 2000).…”

The accompanying CD-ROM contains a compilation of geophysical, geologic, and tectonic data for the Bering Shelf, the Chukchi Sea, the Arctic margin, and adjacent landmasses. These data sets focus on Alaska, the Russian Far East, and the continental shelves that link these two landmasses. For compatibility with other available geographic information system (GIS) products, our GIS compilation extends from 120°E to 115°W, and from 40°N to 80°N. This area encompasses the region from the modern Paciµc plate boundary of the Japan, Kurile, and Aleutian subduction zones, the Queen Charlotte transform fault, and the Cascadia subduction zone (in the south) to the continent-ocean transition from the Eurasian and North American continents to the Arctic Ocean (in the north); and from the diffuse Eurasian-North American plate boundary, including the probable Okhotsk plate (in the west) to the Alaskan-Canadian Cordilleran fold belt (in the east). The CD-ROM comprises thematic layers of spatial data sets for topography, gravity µeld, magnetic µeld, earthquakes, volcanoes, geology, tectonostratigraphic terranes, and cultural reference features, and also includes metadata (data about the data) for all these data sets. The spatial data sets can be viewed, analyzed, and plotted with commercial GIS software (ArcView and ARC/Info) or through a freeware program (ArcExplorer) that is included on this CD-ROM. This GIS compilation provides data for studies of the Mesozoic and Cenozoic collisional and accretionary tectonics that assembled this continental crust and of the neotectonics of active and passive plate margins in this region, and for constructing and interpreting geophysical, geologic, and tectonic models of the region. *

“…It is traced in a northwesterly direction and controls the distribution of orogenic gold (Sana, Drazhnoe, Levoberezhnoe, Pil', Malo-Tarynskoe, Yakutskoe), intrusion-related Au-Bi (Ergelyakh), gold-antimony (Sarylakh, Maltan, Tan), tin-tungsten (Bekkemskoe, Rep-Yuryue, Baryllyalakhskoe), and silver (Veshnee) deposits ( Figure 1). The deposits were formed at different stages of the tectono-magmatic history of the region [35][36][37][38]. The Late Jurassic-Early Cretaceous time was marked by the collision of the Siberian craton and the Kolyma-Omolon microcontinent accompanied by folding and faulting, intrusion of S-and I-type granitoids, and formation of orogenic Au and intrusion-related Au-Bi and Sn-W deposits.…”

Granitoids of the Ergelyakh Intrusion-Related Gold–Bismuth Deposit (Kular-Nera Slate Belt, Northeast Russia): Petrology, Physicochemical Parameters of Formation, and Ore Potential

This paper describes features of petrographic and chemical compositions and isotopic dating of the Ergelyakh and Sokh plutons, located within the Kular-Nera slate belt, Verkhoyansk-Kolyma folded region (VKFR), Northeast Russia. Intrusion of the massifs took place approximately 145–150 million years ago. Different isotopic systems on the whole rock samples and mineral separates record at least two stages of later tectono-magmatic activity 130–120 and 110–100 million years ago. Granitoid magmas for the Ergelyakh and Sokh plutons were formed at high temperatures (950–1060 °C) within the amphibolitic lower crust of an island arc setting. The ages of crustal protoliths for granitoids of the Ergelyakh intrusion-related gold–bismuth deposit, calculated on Rb–Sr and Sm–Nd two-stage models, are 1109–1383 and 1199–1322 million years, respectively. Formation of the Ergelyakh and Sokh plutons took place within a significant temperature interval (<450 to 901 °C) and, with regard to the superposition of later events, lasted for a long time. During the cooling process of granitoid melts, at the time of biotite crystallization in both massifs, a significant increase of oxygen fugacity was registered. The ore potential of granitoids of both massifs seems to be similar, but due to some differences in the physicochemical parameters of their formation (redox conditions), it was partially realized only within the Ergelyakh massif with the generation of several minor intrusion-related gold–bismuth deposits. Granitoid melts of the Ergelyakh massif were formed in relatively heterogeneous and oxidizing conditions (∆Ni–NiO = +3.26 to –3.60). Granitoid melts for the Sokh massif (∆Ni–NiO = –2.88 to –9.27) were formed in reducing conditions.
