| 摘 要： | 采用岩相学、痕量元素分析等方法,对产自贵州黔南罗甸境内的透闪石岩进行了初步研究,该透闪石岩化学成分特点与软玉平均值接近,但具有高钙低镁的特点;组成矿物中,偏光显微镜、IR、XRD等揭示其为较纯的透闪石,透闪石含量一般大于95%,多在98%以上。显微结构研究表明,该透闪石岩中透闪石因普遍发育的交织结构,纤维间的互相穿插绞...

| Abstract: | In this paper,tremolitite in Luodian is studied by petrography,trace element analysis and other method,the chemical content of this tremolitite is similar to the average value of nephrite,different in the character of high calcium and low magnesium.In the component minerals,it’s showed to be pure tremolitite by polarizing microscope,IR and XRD,the content of tremolitite is more than 95%,most is more than 98%.The microstructure study shows: the pilotaxitic texture is found in this tremolitite,the alternation of fibers makes it higher hardness and toughness than Hetian jade and Qinghai jade,has the basic characters of quality jade.The primary field study shows: tremolitite occurs in the contact metasomatic metamorphic belt,appears as banding vein,is a new kind of jade,has some geological reserves and can be explored as jade. |
