ON THE ORIGIN OF NATURAL BITUMEN AT YASNOYE-8 (SAKHALIN ISLAND)

In this study, we analyze samples of a black substance that was used for restoring a Tym-type vessel at Yasnoye-8, Central Sakhalin. On the basis of similar fi nds from the Japanese archipelago, it was initially assumed to be natural bitumen. However, science-based methods have not been previously u...

Description
Summary:In this study, we analyze samples of a black substance that was used for restoring a Tym-type vessel at Yasnoye-8, Central Sakhalin. On the basis of similar fi nds from the Japanese archipelago, it was initially assumed to be natural bitumen. However, science-based methods have not been previously used to test this assumption. In addition to the identifi cation of natural bitumen, we sought to identify its source. The study was carried out independently at two laboratories, using geochemical and petrographic methods, so the results can be considered reliable. For the fi rst time in Russia, the method of pyrolysis gas chromatography – mass spectrometry was used, along with elemental and petrographic analysis, to identify hydrocarbon from an archaeological site. The results confi rm the use of natural bitumen during the Early Iron Age. It can be procured in suffi cient amounts on Sakhalin Island. Identifi cation of specifi c sources is complicated by the virtually complete lack of geological data (bitumen is not mined for industrial purposes). Available materials suggest that bitumen found at Yasnoye-8 originates from the northern Sakhalin petroleum zone or from adjacent areas. No relationship to bitumen deposits in northeastern Honshu was found. Nor is it likely that the sample is related to superfi cial hydrocarbons of Hokkaido. Представлены результаты исследования образцов вещества, из которого выполнены ленты для реставрации сосуда тымского типа с памятника Ясное-8 в центральной части о-ва Сахалин. На основании аналогичных находок на Японском архипелаге уже изначально предполагалось, что оно является природным битумом. Однако до настоящего времени для подтверждения этого предположения не использовались возможности естественных наук. Кроме идентификации природного битума ставилась задача установления его источника. Изучение образцов проводилось в двух независимых лабораториях различными методами геохимии и петрографии, что позволяет говорить о достоверности полученных результатов. Впервые на территории России ...
