| 摘 要： | 本文以辽宁兰家沟钼矿床为例，说明了石英变形纹数字动力学分析（ＮＤＡ）技术的原理、方法及其在控矿构造研究中的应用。在弱变形情况下，该技术能够较为快速、定量地提供控矿古构造应力场的有关信息。应用效果与构造岩结构及定向薄片产状有很大关系。

| Abstract: | In relatively weakly deformed areas such as the Lanjiagou Mo deposit,Liaoning Province,quartz deformationlamellae numerical dynamic analysis (NDA)technique is useful to extract quickly quantitative information of anore-controlling structural stress field. Effectiveness of the application is strongly bound up with factors such as attitudes of the directional sections, textures of the tectonites. |
