中文摘要：

福建寿山高山桃花石具有独特优美的颜色特征，其中红色斑，电的深浅与大小不一。主要采用光学显微镜、X射线粉末衍射仪（XRD）和拉曼光谱仪（LRM）对高山桃花石样品的颜色成因进行了研究。光学显微镜的观察结果表明，高山桃花石样品中存在透明和不透明矿物，其中不透明矿物形成了艳丽的红色斑，点；XRD测试表明，样品的矿物组成为地开石、赤铁矿、石英以及少量的叶腊石；拉曼光谱测试结果表明，样品的基质部分为地开石，结晶形态完好的红色矿物颗粒与呈浸染状的红色部分均为赤铁矿，无色透明的矿物颗粒为石英。呈浸染状的赤铁矿多围绕晶形完好的赤铁矿分布，该分布特征决定了高山桃花石中的红色斑点有大有小，有深有浅。

英文摘要：

The peach blossom stone from Gao Mountain, Shoushan County, Fujian Province, is of unique and beautiful characterisitc of the colour,in which the red spots have different shade and size. The colour causing of the samples from Gao Mountain are studied by means of optical microscope, XRD and LRM. Under optical microscope,the observational result indicates that the peach blossom stone samples from Gao Mountain contains transparent and distransparent minerals which forms pealike and red spots. The XRD testing result indicates that the mineral compositions in the samples are diekite, hematite, quartz and a little pyrophyllite. LRM testing result shows that the basic part of the samples is dickite, the red minerals with both well crystal shape and dip-dye shape are hematite, and colourless and transparent mineral grains are quartz. What is more, the distributing characteristics that the hematite being dip-dye shape commonly surrounds the well hematite crystal, cause the red sports in the peach blossom stone from Gao Mountain different shade and size.
