摘　　要：通过对研究区进行野外观测,对重点区域进行大量的构造要素测量,分析了梭罗沟金矿一带现今构造变形特征。矿区北侧的构造变形强度从西向东呈现出整体增强的趋势。矿区北侧西段处挤压应力为S-N向与NW-SE向挤压,中段为NW-SE向挤压,在东段转为S-N向挤压。梭罗沟金矿区构造变形强度总体上呈现出东部变形强烈,西部变形较弱,从西向东为增强的趋势。将矿区西段、中段、东段分别与矿区北侧西段、中段、东段进行对比,可以看出矿区的构造变形程度明显低于矿区北侧。整个梭罗沟金矿一带从北向南,从东到西变形程度呈现出减弱的趋势,挤压应力主要来自于北方、东方,或者北东方向。梭罗沟金矿一带经历了多期次应力作用,由于受到来自于北西向的挤压应力,金矿区中段观测处呈现出右行走滑,而在东段观测处呈现出左行走滑。The degree of tectonic deformation of the Suoluogou Au deposit increases gradually from west to east.The compressive stress at the west section of the north side of the deposit was longitudinal direction,at the middle section was NW-SE direction and at the east section was longitudinal direction.The compressive stresses was mainly from the north,east,or north-east direction.The Middle section shows a right-hand slip,while the eastern section shows a left-lateral strike-slip.
