对新疆阿尔泰地区的芙蓉石及其围岩.白色半透明石英进行了三维热释光谱的分析。芙蓉石在170℃有2个低温热释光峰,发光波段分别为480nm和630nm,而白色石英只有480nm 1个低温峰。480nm波段处的热释光峰是深成岩浆岩石英中最常见的峰,释光中心是Si位置上的(AlO4)^0;表明芙蓉石是深成岩浆作用形成的。630nm、170℃~210℃处的低温热释光峰是芙蓉石的特征热释光峰,可能是由于Fe^3+置换Si4+晶格位置形成的[FeO4]^0芯所引起的。本文还检测到荚蓉石和围岩石英在990nm、330℃处存在很强的高温热释光峰。
The rose quartz is a gemstone of quartz family minerals. Three dimension thermoluminescence spectra of rose quartz and wall rock quartz from in Altay, Xinjiang were analyzed. The 3D TL spectra of rose quartz have two low temperature TL peaks at 480 nm and 630 nm at 170℃, but only one peak at 480 nm is seen in wall rock quartz. The TL peak at 480 nm is related to hypogene magmatism and its luminescence centre is probably (AlO4)^0 on a Si site, which indicate that rose quartz were formed by hypogene magmatism. The TL peak at 630 nm and 170℃ appears to be characteristic of the rose quartz and is proposed to be due to [FeO4]^0 center from the substitutional incorporation of Fe^3+ into the quartz lattice. An intense TL peak at 990 nm and 330℃ is also detected in both rose quartz and wall rock quartz.
