| 摘 要： | 本文在对拉日玛金矿床区域地质背景、矿床构造基本特征研究的基础上，同步运用激光光弹模拟实验、动态重结晶石英、石英位错密度、应变藻球粒等方法与手段，对矿床构造不同变形区段、不同位置的构造能量、古应力（动力）的分布及作用，进行了配套研究。结果表明：成矿元素的活化、成矿流体运移势、矿体定位，固然受构造变形空间的控制，更为重要的是构造动力作用参与了成矿，并受动力作用强、弱的支配。因此，对于金矿床的形成而论，构造动力作用是决定的主因。

| Abstract: | On the basis of regional geologic setting and structural feature of Larima gold deposit in combination with laser medel experiment ,dynamic recrystallization of quartz ,dislocation density of quartz and strain algal spherulite ,tectonic energy and paleostress state in different tectonically deformed sectors of the deposit are comprehensively researched. The research indicates that remobilization of ore-forming elements,migration power of the ore fluid and emplacement of the orebodies were controlled by space from tectonic deformation and that tectonic dynamic took part in the ore-formation. Therefore ,tectonic dynamic played a decisive role in the formation of Larima gold deposit. |
