摘要
论述了石英的微量元素、稀土元素、包裹体、热发光的标型特征及其在矿床成因研究和找矿意义。石英中Ｋ＋，Ｎａ＋，Ａｌ３＋以类质同象代替Ｓｉ４＋，Ｋ２Ｏ／Ｎａ２Ｏ比值可判定矿化深度。成矿温度３０５～３４３℃，成矿物质来源于深部。
The present paper deals emphatically with such typomorphic characteristics of quartz from Yuerya gold deposit as trace elements, REE, inclutions, natural themoluminescence as well as its significance in the study of ore genesis and prospecting. Investigation shows that K +, Na + and Al 3+ are substituted in the lattice of quartz, that K 2O/Na 2O of quartz can be used in judging depth of mineralization, that the mineralizing temperature of Yuerya gold deposit is 305～343℃, and that ore-forming fluid in Yuerya gold deposit originates from the deep crust.
