“…Sparsely populated territories are characterized by barren and otherwise physically unattractive environmental conditions, which can incur additional costs for labor [38] and life-maintaining services, complicate access to energy supplies, and limit technological access and safety conditions [39]. Northern SPTs represent an area of significant natural capital, primarily in the form of mineral resources [27,40]. Natural capital refers to those circumstances intrinsic to the environment that can be capitalized upon by humans, including geographical features and natural ecosystems [41], cryogenic resources [42], and regulatory processes [43], as previously defined.…”

Extreme environmental conditions, sparsely distributed human populations, and diverse local economies characterize the Russian Arctic and Far East. There is an urgent need for multidisciplinary research into how the Arctic and Far East can be developed sustainably as global changes in the environment and the economic priorities of nations accelerate and globalized societies emerge. Yet, when it comes to sustainability indicators, little consideration has been given thus far to sparsely populated and remote territories. Rather, the majority of indicators have been developed and tested while using empirical research gathered from cities and densely populated rural localities. As a result, there is no scientific technique that can be used to monitor the development of sparsely populated territories and inform the decisions of policymakers who hope to account for local specificity. This article suggests a conceptual model for linking sustainability to the unique characteristics of the sparsely populated regions of the Arctic and Far East. We provide an empirical illustration that is based on regional-level data from the sparsely populated territories of the Russian Federation. We conclude by suggesting indicators that could be best suited to promoting balanced regional development that accounts for the environment, economy, and social needs of sparsely populated territories.

Статья поступила в редакцию 30 октября 2018 г. На основе пространственно-статистического ГИС-анализа в статье оценены перспективы развития добычи стратегических минеральных ресурсов в Циркумарктическом поясе (ЦАП). Несмотря на вековую историю горнодобывающих работ, недра ЦАП содержат еще достаточное количество минерального сырья. Однако наибольшее значение для горнодобывающей промышленности в ЦАП в настоящее время имеют Ni, Cu, металлы платиновой группы, Di 1 , P 2 O 5 , Zn, Pb, Au, Ag, Fe-руды, Ti и др. Полученные результаты основаны на анализе наиболее полной базы данных, составленной по месторождениям различных минеральных типов российской и зарубежной Арктики. Выполненный анализ показал, что современное состояние минерально-сырьевой базы ЦАП вполне удовлетворительно и обеспечивает устойчивое развитие экономики стран в его пределах. Такую же оценку можно дать и по отдельным секторам ЦАП. Горнодобывающая промышленность, несмотря на экологические проблемы, имеет значительные перспективы развития практически во всех секторах ЦАП и в частности на территории Арктической зоны России.

Composition and origin of a K2O-rich granite melt in the Mid-Atlantic Ridge, 13°34′ N: Evidence from the analysis of melt inclusions and minerals of the gabbro-plagiogranite association

Participation of seawater in large scale convective circulation in the global system of mid ocean ridges is an important factor of heat and mass transfer resulting in cooling and hydrothermal alteration of the newly formed basic crust and precipitation of sulfide-poly metallic ores on the oceanic floor [1,2]. The deep zones of hydrothermal systems and the areas of hydro thermal-magmatic interaction are the least studied. It is suggested that the local partial melting of the basic crust under the influence of hydrothermal seawater derived fluids and the appearance of oceanic plagiog ranite (OPG), i.e., plutonic quartz-feldspar rocks with occasional pyroxene and hornblende, may be one of the extreme manifestations of such interaction [3,4]. However, there are other models of OPG origin: extreme differentiation of basaltic magma, phase sep aration of differentiated basaltic magma, magmatic assimilation, and partial melting of the hydrated crust [3]. Although the phenomenon of acid magmatism in the modern oceanic crust and paleoanalogs is of spe cial interest, the likely combinations of various petro genetic factors in the generation of OPG melts are poorly studied. In particular, the role of the basic crust composition is not clear.In this paper, we report the results of the study of an occasional biotite bearing gabbro-plagiogranite assemblage discovered in the Mid Atlantic Ridge (MAR), where the formation of the oceanic crust is significantly controlled by mantle magmas of the E MORB type enriched in incompatible elements. The composition of the granitoid melt was estimated by the study of melt inclusions in zircon, the bulk chemistry of OPG veinlets, and clinopyroxene/melt REE parti tioning.The gabbro-peridotite (strongly serpentinized) massif exposed in the footwall of the large offset low angle detachment fault in the range of 13°28′-13°35′ N on the western slope of the MAR was studied and sampled in three cruises of R/V Professor Logachev in 2007-2011 (Fig. 1). It is established that the structure of the massif is complicated by volcanic formations and a series of hydrothermal sulfide fields. In addition, samples of OPG veinlets in amphibolite and gabbro, as well as massive OPG rocks, were dredged at 8 sites ( Fig. 1) [5]. The analysis of fresh lavas with quench glasses from 21 sampling sites showed that within the massif the composition of magmas of volcanic struc tures varied from normal (Nb N /Zr N = 1.2; H 2 O (8) = 0.15 wt %; K 2 O = 0.04 wt %; 87 Sr/ 86 Sr = 0.7024) to sig nificantly enriched (Nb N /Zr N = 3.5; H 2 O (8) = 0.45 wt %; K 2 O = 0.7 wt %; 87 Sr/ 86 Sr = 0.7029) oceanic basalt.Biotite bearing OPGs were found at Sites 97 and 101, on the northern margin of the massif, at a dis tance of ~3 km from each other (Fig. 1). They occur as fine grained biotite-quartz-plagioclase veinlets in coarse graned gabbro. Gabbroids and hydrothermally altered mafic rocks prevailed among the dredged sam ples. Mafic rocks contain quartz-sulfide mineraliza tion. There are samples of massive biotite free OPG as well.S...
