摘要
为了探究南岭地区晚中生代与钨锡成矿有关的花岗岩锆石辐射损伤情况及其对U-Pb年龄的影响,本研究采用激光拉曼光谱分析的方法,对赣南铁山垅钨矿成矿花岗岩进行了锆石形态及拉曼光谱特征分析。发现其锆石主要为颜色较浅的低铀锆石和颜色较深的高铀锆石。前者激光拉曼谱线显示出跟标准锆石类似的峰值特征,后者一般较为平坦。锆石形态及激光拉曼研究结果表明,锆石受到了流体作用影响,花岗岩形成于岩浆热液过渡时期。赣南乃至华南晚中生代成岩成矿作用存续时间较长,岩浆热液过程影响深远。
To explore the granite zircon radiation damage related to tungsten-tin mineralization in the late Mesozoic in the Nanling region and its influence on the U-Pb age,the paper analyzed the characteristics of zircon morphology and Raman spectroscopy of metallogenic granite in Tieshanlong tungsten deposit,southern Jiangxi province by laser Raman spectroscopy.The results show that the zircons are mainly light-colored zircons with low uranium and dark-colored zircons with high uranium.The laser Raman spectral lines of the former zircons demonstrate similar peak features to that of the standard zircon,while the latter is generally flat.The results of zircon morphology and laser Raman manifest that zircon is affected by fluid,and granite is formed in the magmatic-hydrothermal transition period.The petrogenesis and mineralization last a long time in the late Mesozoic in southern Jiangxi province and even South China,and the magmatic-hydrothermal has a deep effect.
