    摘要:

    乌拉嘎、平顶山、老柞山金矿是佳木斯地块三个重要的金矿。研究表明,石英是金 矿中重要的脉石矿物,也是金的主要载体。SiO2含量低于98%,而∑(Al2O3+K2O+Na2O)含量 高于1.3%的石英为含金石英;含金或富含金石英的热释发光谱以双峰或多峰为其主要特征。 因此,上述石英的标型特征可作为金矿床重要的找矿标志,对佳木斯地块的矿点评价和扩大找 矿远景有着重要的意义。

    Abstract:

    Wuliga, Pingdingshan and Laozuoshan gold deposits are three important gold deposits in Jiamusi Massif. Studies show that quartz is not only an important gangue mineral but a main carrier of gold as well. Quartz with SiO2content lower than 98% but∑(Al2O3+K2O+Na2O) content higher than 1.3% is auriferous quartz, whose thermoluminescent spectra are characterized by double or multiple peaks. Therefore, these typomorphic characteristics serve as important ore-prospecting indicators for gold deposits and are hence of great significance in evaluation of ore occurrences and broadening of ore-prospecting vista in Jiamusi Massif
