| 摘 要： | 雪峰山中段铲子坪和大坪等金矿区目前发现的岩金矿脉均赋存于剪切带中，说明剪切作用本身也就是成矿作用。通过剪切作用过程中的应力分析，发现剪切带中金矿脉走向与剪切带走向的交角遵循一定的数学关系，从而提出二者交角的数学表达式，该数学表达式推算出的理论值与实测值可以相互对照。

| Abstract: | At present, gold ore veins which were found in Au mine district of Daping and Chanzhiping at middle Xuefengshan mountain range occur in shear zone, it indicates that shear action is just metallogenesis. Based on the stress analysis during shear process, the author finds that the intersection angle between strike of Au ore vein and shear exists the math's relationship, and puts forward the intersection angle's math's formula, the theory value being calculated by the math's formula can match with the practice measure one each other. |
