【摘要】：青海都兰位于古丝绸之路南道上,都兰吐蕃墓葬群出土了为数不少的隋唐时期金银器及饰物,其中一件"粟特银包金神垱人物连珠牌饰银丝腰带"牌饰上的人物具有典型的粟特特征,这对于研究中西方文化交流,有着极为重要的价值。但很多包金银饰片出土时腐蚀严重需要进行保护处理和相关的科学研究。为此,通过电子扫描电镜、X-射线衍射等分析方法,对工艺类似腰带牌饰的样品进行科学分析。结果表明,样品为包金银器饰物,包金层为金银合金,而银本体腐蚀严重,腐蚀产物主要是氯化银,这与环境的高含盐量有关,分析结果可为吐蕃墓出土文物的研究和保护提供理论依据。
[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.
