摘要:
利用X射线粉末衍射仪、拉曼光谱仪、扫描电子显微镜、电子探针及岩石薄片对昌化鸡血石样品中“地”与“血”的矿物组成、形貌特征、化学成分等进行了研究。结果表明,昌化鸡血石“硬地”“软地”与“冻地”的矿物组合不同;其中,“地”以地开石为主且呈鳞片状,随着石英的增加,特别是明矾石的加入,“地”的硬度变大。“冻地”鸡血石中地开石的结晶粒度比“硬地”鸡血石中的大,但其空间定向性排列没有后者的好。昌化鸡血石中“血”由细小的半自形—他形辰砂微晶集合体组成,其“血”色与辰砂晶体的聚集状态及其杂质成分有关,而杂质成分又与Se元素的质量分数密切相关。

Abstract:
The mineral components,morphological characteristics and chemical compositions of the "Di" and "Blood" of the chicken-blood stone samples from Changhua are studied by means of XRD,LRM,SEM and EPMA with rock slick.The results show that the mineral combinations are quite different among the "Ying Di""Ruan Di" and "Dong Di" of the chicken-blood stone samples.The "Di" is mainly composed of dickite being squama-like.As quartz increases,especially alunite,the rigidity of the "Di" becomes harder.The crystal granularity of the dickite in "Dong Di" is larger than that in "Ying Di" of the chicken-blood stone samples,and the space direction of dickite in "Dong Di" is not good as that in "Ying Di" samples.The "Blood" in the chicken-blood stone sample is composed of fine hypidiomorphic—altotriomorphic cinnabar minicrystal aggregation,where the colour is related with the assemble state of cinnabar crystal and its impurity composition which has correlation with the content of Se.
