摘要
对产于新疆阿舍勒铜矿的黄铁矿和金鑫金矿的含金黄铁矿进行了二维热释光、三维热释光和光释光分析。铜矿中黄铁矿与含金黄铁矿的热释光特征存在明显差异 ,铜矿中黄铁矿的热释光和光释光强度显著高于含金黄铁矿 ,铜矿中黄铁矿的热释光峰温度比含金黄铁矿高 15— 30℃ ;三维热释光分析中铜矿中黄铁矿的低温 (130—170℃ )发光峰波长为 72 0nm ,含金黄铁矿为 390nm。由于杂质元素的不同而导致黄铁矿的晶体结构和芯型也不同 ,铜矿中黄铁矿主要为电子芯型 ,含金黄铁矿主要为空穴芯型。
The characters of 2D TL, 3D TL and OSL of pyrite occuring in Ashele copper deposit and Jinxin gold deposit, Xinjiang were analyzed. There existed notable difference in TL and OSL of pyrite in copper deposit and auriferous pyrite in gold deposit. The intensity of TL and OSL of pyrite in copper deposit is larger than that in gold deposit. The TL peak temperature of pyrite in copper deposit is about 15-30℃ higher than that in gold deposit. In 3D TL, the wavelength of low temperature (130-170℃) TL peak is 720nm for pyrite in copper deposit and 390nm for auriferous pyrite in gold deposit. The difference of impurity elements results in the difference in crystal texture and center of pyrite, which mainly belongs to electron center type for pyrite in copper deposit and to vacancy center type for pyrite in gold deposit. The different centers brought about the notable difference in TL characters for the two kinds of pyrite.
