The study of the mineralogy indicates:(1)Few impurity and poor sulfur in thestibnite of Shalagang antimony.(2)From the stibnite's cell parameter, it finds that thecell parameter of Shalagang antimony's stibnite approachs the standard value. And iteduces the forming temperature of the stibnite is between 150℃～200℃.(3)Thequartz in different period have different thermoluminescence curve, and thethermoluminescence curves of the quartz in rich ore havethe characters of gently curve, unconspicuous peak and the luminous intensity has therelationship of positive correlation with the temperature.

矿物学研究发现：(1)沙拉岗锑矿床辉锑矿以所含杂质少，贫硫为主要特征；(2)利用晶胞参数测定得出，沙拉岗锑矿床辉锑矿晶胞参数接近于标准值，推算形成温度在150℃～200℃之间；(3)不同期次石英具有明显不同的热释光曲线，其中主成矿期石英的热释光曲线以发光曲线平缓，峰位不明显，发光强度随温度升高而增强为特征。
