桂北南天门金矿区石英的成因矿物学特征

Genetic Mineralogical Feature of Quartz from Nantianmen Gold Deposit in Northern Guangxi Province

矿区石英成分、晶胞参数、热发光、包裹体、红外谱等的研究揭示，石英的杂质含量、１２０℃±和２５０℃±发光峰强、爆裂脉冲数高、多峰等特征，是南天门金矿区的富矿标志，其深部具找矿远景。

The studies on tbe composition,lattice parameters thermoluminescence fluid inclusion,and in-fra一red spectrum of quartz samples from the gold deposit reveal that their impure constituent contents , thermo-luminescent strength at 120C and 250C,high impulse number,and multi一peak feature of explosion when heat-ed, are the indicators for enrichment of gold in Nantianmen gold ore district.It is considered that the deep part of the mine is of good prospect for gold.
