The background content of total petroleum hydrocarbons (TPH) in the most common soils of the Lower Amur region and Northern Sakhalin was determined. About 300 samples taken from the surface layers and horizons of 8 typical soil pedons were analyzed. The accumulative nature of TPH distribution in the soil profile was established, and their highest content was revealed in the organogenic horizons. The soils of eluvial landscapes (Podzols, Spodic Cambisols, Fulvic Cambisols) contain a smaller amount of TPH compared to the soils of accumulative landscapes (Histosols, Fluvisols). The maximum content of TPH was found in the Spodic Hyperalbic Technosols. The content of TPH in the anthropogenic abrasives of the Lower Amur region is estimated as acceptable, the level of pollution in the anthropogenic abrasives in Northern Sakhalin varies from low to very high. The results obtained on the background content of TPH can used for assessing of soils pollution and in conducting ecological monitoring studies.

In recent years, highly liquid precious metals have been mined in the Russian Far East. The state fund has no facilities with confirmed reserves. However, there is a real possibility of reviving the ‘old’ mining areas. Based on the Lower Amur region (Khabarovsk region) the prospects of gold reserves accumulation using ‘small’ fields (in 50-80-s conception) are considered. It deems new to determine the potential of these facilities from the viewpoint of large-scale mineralization and to involve the territory under consideration in the assessment of the gold-bearing manifestations. ‘Reference’ deposits were selected and their specific productivity was assessed, which was extended to similar by properties manifestations. Within the Lower Amur region, geological investigations revealed about 300 small deposits and mineral occurrences. 34 objects localized at the clusters of submeridional and sublatitudinal faults intersection, were identified as promising. Basically, the gold-ore blocks were compared with the ‘standards’: Belogorsky (near-surface), Dyappe (subvolcanic) and Zimovye (hypabyssal). The determining factors were the structural features of mineralization localization, facies conditions, the ores composition and metasomatites, the zonality of ore-metasomatic formations, the erosion of objects and the completeness of hydrothermal processes. The author’s assessment is confirmed by the results of exploration works at 15 ‘small’ deposits and ore occurrences, with the transfer of 11 of them to the category of large and medium-sized.

The purpose of the article is to analyze the significance of the Amur River transport activity in the 1990s for interregional Russian-Chinese cross-border coopera-tion in the Far East. Using the materials in Chinese as well as archival documents, the author examines the process of border ties resumption between Russia and China in the Far East after the normalization of rela-tions between the countries. The peculiarities of the river fleet functioning on the Amur during the period of socio-economic reforms of the last decade of the 20th century in Russia are studied. The characteristic of the Amur River transport potential is presented. The prob-lems of the Amur River transport in the development of cooperation between the Russian Amur Region and the Chinese province of Heilongjiang in the context of Rus-sian-Chinese relations at the interstate and interregion-al levels are structured.

Статья посвящена результатам всестороннего изучения гончарных традиций в технологии, формах и орнаментации посуды у носителей осиповской и мариинской неолитических культур в российском Приамурье. Осиповская культура является древнейшей на земном шаре, и ее керамика отражает первые этапы становления гончарного производства в истории человечества. Керамика мариинской культуры характеризует следующий этап развития гончарства и относится к раннему неолиту на этой территории. Авторы приходят к выводу, что эти культуры оставлены разными в этнокультурном плане группами древнего населения. The paper describes results of the comprehensive study of pottery traditions through the prism of technological processes, shapes and ornamentation of vessels developed by the Osipovka and Mariinskoye Neolithic cultures in the Russian Amur Region. The Osipovka culture is the earliest on our planet and its pottery reflects first stages of pottery development in the history of humanity. The Mariinskoye pottery characterizes the next period of pottery development and is dated to the Early Neolithic of this region. The authors conclude that these cultures were left behind by different ethnocultural groups of the earliest population.
