【摘要】:青海都蘭位于古絲綢之路南道上,都蘭吐蕃墓葬群出土了為數(shù)不少的隋唐時期金銀器及飾物,其中一件"粟特銀包金神垱人物連珠牌飾銀絲腰帶"牌飾上的人物具有典型的粟特特征,這對于研究中西方文化交流,有著極為重要的價值。但很多包金銀飾片出土?xí)r腐蝕嚴重需要進行保護處理和相關(guān)的科學(xué)研究。為此,通過電子掃描電鏡、X-射線衍射等分析方法,對工藝類似腰帶牌飾的樣品進行科學(xué)分析。結(jié)果表明,樣品為包金銀器飾物,包金層為金銀合金,而銀本體腐蝕嚴重,腐蝕產(chǎn)物主要是氯化銀,這與環(huán)境的高含鹽量有關(guān),分析結(jié)果可為吐蕃墓出土文物的研究和保護提供理論依據(jù)。
[Abstract]:Dulan, Qinghai Province, is located on the southern road of the ancient Silk Road. A large number of gold and silver objects and ornaments of the Sui and Tang dynasties have been unearthed in the Tubo tombs of Dulan. Among them, one of the characters on the card of "Sogel silver wrapped in gold god Dang character Lianzhu card and silver belt" has typical special characteristics, which is of great value to the study of cultural exchange between China and the West. However, the corrosion of many gold and silver ornaments unearthed requires protection treatment and related scientific research. For this reason, the samples similar to belt ornaments were analyzed scientifically by means of electron scanning electron microscope (SEM) and X-ray diffraction (XRD). The results show that the samples are decorated with gold and silver, and the gold coating is gold and silver alloy, while the body of silver is corroded seriously, and the corrosion product is mainly silver chloride, which is related to the high salt content in the environment. The results can provide a theoretical basis for the research and protection of the cultural relics unearthed in Tubo tombs.
