摘　　要：为了准确区分不同产地的蛋白石,作者分别选取了多篇国内外研究文献,参考不同的矿床成因,综合比较分析了它们的矿物学特征以及光谱学特征等特征,对现有文献作大致梳理。结果表明,不同产地蛋白石间虽然差异不大,但根据蛋白石不同成因进行鉴定有较好的效果,火山成因型蛋白石与风化壳型蛋白石在光谱图像、色斑特征、结晶程度、内部结构等方面存在显著不同。In order to accurately distinguish opal from different origins,the author selected several domestic and foreign research literatures,referred to the genesis of different ore deposits,comprehensively compared and analyzed their mineralogical characteristics,spectral characteristics and other characteristics,and sorted out the existing literatures.The results showed that although there was little difference between opals from different origins,the identification based on different genesis of opals had better effect.
