Abstract

: Demantoid from Kerman Province in south-east Iran was investigated using microscopy, spectroscopy (optical absorption, FTIR and Raman), chemical analysis (EDXRF and LA-ICP-TOF-MS) and magnetic susceptibility measurements. The samples were transparent to semi-transparent and commonly contained acicular chrysotile inclusions. Their spectroscopic and chemical properties were consistent with demantoid from serpentinite host rock. The samples ranged from yellowish green to deep green, depending on Cr and Fe content. These two elements are also largely responsible for the material’s

伊朗东南部克尔曼省的Demantoid:矿物学和宝石学综述

对来自伊朗东南部克尔曼省的Demantoid进行了显微镜、光谱学(光学吸收、FTIR和拉曼光谱)、化学分析(EDXRF和LA-ICP-TOF-MS)和磁化率测量。样品为透明至半透明，通常含有针状温石棉包裹体。它们的光谱学和化学性质与蛇纹岩寄主岩石的要求样相一致。根据铬和铁的含量，样品的颜色从黄绿色到深绿色不等。这两种元素也在很大程度上负责材料的
