摘　　要：研究东北寨金矿床石英的化学成分、稀土元素、晶胞参数、红外吸收光谱、热发光效应等方面的矿物学特征,提取了有参考价值的成因信息和找矿标志。认为东北寨金矿床系浅成低温热液成因。其矿质来源于地层围岩,并指出有一定的铝碱含量(0.1903％～0.3004％)、含少量砷(5.58×10^(-6)～34.56×10^(-6)、晶胞参数V_0>112.742A^(03)、红外光谱向低频方向移动几个波数,具三峰型热发光曲线(320～330℃、340～350℃、350～380℃)特征的石英是寻找“东北寨”金矿的重要找矿标志。The quartz of mineralogic characteristics of the chemical composition,REE,unit cell parameter,infrared absorption spectra,themoluminescence effect et al. from Dongbeizai gold deposit were studied in this paper. The valuable information of genetic and prospecting criteria are got. The authors consider that Dongbeizai gold deposit is an epithermal one,the gold source was from wallrock. The quartz with some aluminium and corresponding alkaline elements (0. 1903%-0. 3004%)and As(5. 58×10-6-34. 56×10-6,unit cell parameter V0>112. 742 A03, infrared spectrum displacement several wavenumber toward low frequency and with three peaks thermoluminescence curve (320-330℃,340-350℃,350-380℃)are the important prospecting criteria for searching Dongbeizai type'gold deposits.
