| 摘 要： | 本文通过青海都兰沙柳河多金属矿床控矿构造的宏、微观特征的研究，确定了矿区不同方向控矿构造的形变历史；近ＥＷ向构造至少有３期构造变形，即一期塑性变形和至少两脆性变形，ＮＷ向和ＮＥ向构造各具有两构造变形，本文还探讨了矿区构造演化史和不同方向构造在矿产形成中的作用。

| Abstract: | Based on the study of the mega and micro ore-controlling structures in the polymetallic ore deposits in Shaliuhenanqu,Dulan,Qinghai Province,the deformation histories of variously trending structures were determined:E-W-trending structure experienced at least three stages of deformation,the NW-trending and the NE-trending structures two stages of deformation each.Therefore,the authors proposed the tectonic development of that area and also discussed the role of the variously oriented structures in the formation of the deposit. |
