| 摘 要： | 采用X射线粉末衍射仪、扫描电子显微镜(配能谱仪)、红外光谱仪分别对产自福建省寿山溪流域的田黄样品的基体、"萝卜丝纹"、风化皮部分的矿物组成及其微形貌特征进行了初步研究.结果发现,田黄样品主要由高岭石族矿物中的地开石与珍珠陶石组成,有的样品中还含有少量的伊利石与石英,其中在基体与"萝卜丝纹"部分中未发现高岭石的存在,而在风化皮中则发现有高岭石.田黄基体中高岭石族矿物的晶体颗粒大小不等,结晶程度不同.有的"萝卜丝纹"与基体的交界处存在一定界限.风化皮中的高岭石族矿物由于水岩反应以及外力作用已失去了具体晶形,但在其表面凹坑中高岭石族矿物仍保持完好的结晶形态. |

| Abstract: | The Tianhuang samples from Shoushan rivulet in Fujian Province are studied respectively on the mineral components and micro-morphological characteristics of the body,Luobosiwen and weathering skin parts by means of XRD,SEM(EDX)and FTIR.The results show that the Tianhuang samples are mainly composed of dickite and nacrite of kaolin-group minerals,but some contain a little of illite and quartz.There is no kaolinite in the body and Luobosiwen parts,but found in the weathering skin part.The crystal size and cry... |
