【摘要】：琥珀是中生代白垩纪至新生代第三纪松柏科和豆科植物的树脂,经过复杂的地质作用而石化形成的一种天然有机混合物。对于相同产地的琥珀而言,琥珀原石通常具有不同的颜色和透明度,而不同产地的琥珀品种其颜色、透明度和宝石学特征方面的差异更明显。本文以不同产地琥珀样品为研究对象,利用折射仪、比重仪和荧光仪等测试方法,对琥珀的基本宝石学特征和包裹体特征进行研究;利用红外光谱、拉曼光谱、紫外可见分光光度计对各种琥珀样品进行光谱学特征测试,与前人对有机物官能团在谱图指示峰位进行比对,剖析了琥珀所含C官能团种类和所含有机物分子特征;通过对不同产地琥珀的稳定性、成熟度、对称性、氧化程度等进行量化比较分析研究,取得了不同产地琥珀的多种宝石学和谱学特征数据,为琥珀的深入研究提供一定的科学依据。通过对琥珀特性的比对研究,不但丰富了现有的理论知识,填补研究的空缺,对市场具有指导意义。一方面,很多宝石的研究和甄别都可以借鉴论文中研究琥珀的方法,从而拓宽了其他宝石鉴别的途径。另一方面,由于对琥珀研究的丰富和发展,对琥珀市场也有着较大的促进作用,能有效的防控一些仿制品的流通,有利于市场的有序发展。
[Abstract]:Amber is a natural organic mixture formed from Mesozoic Cretaceous to Cenozoic Tertiary pine cypress and legume plants through complex geological processes. For amber from the same producing area, amber protostones usually have different colors and diaphaneity, but the color, transparency and gemology characteristics of amber varieties from different producing areas are more obvious. In this paper, the basic gemstone characteristics and inclusion characteristics of amber were studied by means of refractometer, specific gravity meter and fluorescence spectrometer. The spectroscopic characteristics of various amber samples were tested by UV-Vis spectrophotometer. Compared with the former ones, the types of C-functional groups and the molecular characteristics of organic compounds in amber were analyzed. The stability, maturity, symmetry and oxidation degree of amber from different producing areas were compared and analyzed quantitatively, and various gemology and spectrum characteristic data of amber from different producing areas were obtained. It provides a scientific basis for the further study of amber. The comparative study of amber properties not only enriches the existing theoretical knowledge, fills the gaps in the research, but also has a guiding significance for the market. On the one hand, the research and discrimination of many gemstones can draw lessons from the methods of amber research in this paper, thus widening the ways of identifying other gemstones. On the other hand, because of the rich and development of amber research, Amber market also has a greater role in promoting, can effectively control the circulation of some imitation products, conducive to the orderly development of the market.
