The marginal location of the Sea of Japan and its constrained water exchange with the western Pacific make this sea a subtle subject for the investigation of orbital and suborbital climate changes. However, the response of this unique basin to the climate and sea level changes at the end of the last glaciation and deglaciation and during the Holocene is not fully understood. We provided detailed reconstructions of the dark layers including the timing and mechanisms responsible for their formation, during the last 40°kyr, based on the multiproxy correlation of three cores from the northern and central parts of the sea with well-dated δ18O records of the Greenland ice and China cave stalagmites. High resolution color photo lightness, the conventional color parameters L* and b*, AMS 14C data, chlorin and carbonate calcium content and pollen climate parameters allowed the correlation of the DLs of these cores with Greenland interstadials (GI), Heinrich stadials (HS) and summer East Asian monsoon intensity. DLs 9, 8, 7, and 6, formed after Heinrich stadials 4 (38.5–39.5°ka), were triggered by GIs 8, 7, 6 and 5, coeval with the intensification of the East Asian summer monsoon and the increase of surface water stratification and productivity. The long-lasting GI 8, accompanied by significant climate warming, led to the formation of the more intense DL 9. The accumulation of DL five was forced by a rapid global sea level fall, coeval with cold HS 3, due to the decrease of saline Tsushima Current water input into the sea, increased surface water stratification and a drop in deep water ventilation. DL four was probably launched by GI 3 and summer East Asian monsoon intensification. Further falls in global sea level during the last glacial maximum led to the formation of DLs 3 and 2 during the periods 27.0–24.2°ka and 23.5–17.0°ka, respectively. DL 1 was associated with significant summer East Asian monsoon intensification and environmental warming at the onset of the Holocene.

Морское побережье является одной из самых выраженных естественных географических границ, которая одновременно разделяет и связывает географические структуры суши морей или океанов. В основе формирования типов природопользования в прибрежных зонах, как и на других типах географического пространства, лежит природноресурсный потенциал. Природноресурсный потенциал и типы природопользования как явления пространственнодифференцированные должны быть рассмотрены, прежде всего, в рамках классических географических подходов и оценок, таких как районирование территории и акватории. При этом пространственные сочетания наземных и морских природных, природноресурсных компонентов рассматриваются как важнейшие предпосылки инфраструктурного и хозяйственного развития прибрежных регионов. Необходимым этапом природноресурсного районирования является выявление границ, при пересечении которых существенно меняются природные ресурсы и условия. Данная работа выполнена на примере рассмотрения минеральных ресурсов прибрежных муниципальных образований и является частью исследования природноресурсных сочетаний зоны сушаокеан Дальнего Востока России в рамках изучения пространственной дифференциации факторов, условий и ограничений формирования и развития структур природопользования в прибрежной зоне Тихоокеанской России с учетом воздействия экстремальных природных процессов и явлений. Дана сравнительная характеристика месторождений минерального сырья российской части побережья Японского моря. Определена их видовая и географическая структура. На основе того, что месторождения минерального сырья сгруппированы в 8 основных ресурсных групп ввыполнено районирование российской части побережья Японского моря по сочетанию основных видов минеральных ресурсов. Выделены типы муниципальных образований по сочетанию минеральных ресурсов и показаны особенности каждого из них. Выделены шесть районов по сочетанию минеральных ресурсов. В связи с необходимостью учета географической особенности в сочетании со спецификой минеральных ресурсов, северной и южной частям территории одного типа районов присвоены свои собственные названия. По результатам исследования была построена карта. The seacoast is one of the most pronounced natural geographical boundaries, which divides and connects simultaneously the geographical structures of the land, seas or oceans. The formation of the types of nature management in coastal zones, as well as on other types of geographical space, is based on the natural resource potential. Being spatially differentiated phenomena, the natural resource potential and the types of environmental management should be considered, first of all, within the framework of classical geographical approaches and assessments, such as zoning of the territory and water areas. In this case, spatial combinations of the land and sea natural, naturalresource components are considered as the most important prerequisites for the infrastructure and economic development of coastal regions. Identification of borders, at the intersection of which the natural resources and conditions change significantly, is a necessary stage of natural resource zoning. This work is carried out by example of consideration of mineral resources of coastal municipal unions and appears to be a part of studies of naturalresource combinations of the landocean zone of the Russian Far East in the framework of studies of spatial differentiation of factors, conditions and restrictions of formation and development of structures of nature management in the coastal zone of Pacific Russia, taking into account the influence of extreme natural processes and phenomena. The comparative characteristic of mineral deposits of the Russian part of the coast of the Sea of Japan is given. Their species and a geographical structure are determined. Based on the fact that the mineral deposits are grouped into eight main resource groups, zoning of the Russian part of the coast of the Sea of Japan by a combination of the main types of mineral resources is performed. The types of municipalities are allocated by a combination of mineral resources and their features are shown. Six areas are singled out by a combination of mineral resources. Due to the need to take into account the geographical features in combination with the specifics of mineral resources, the northern and southern parts of the territory of one type of areas have obtained their own names. According to the results of the studies, the map has been compiled.
