| 摘 要： | 肖板金矿床控矿构造是在变质岩构造基础上发育起来的蒲洋变质核杂岩构造之北西侧的剥离构造－低角度正断层系，具有产状平缓、延伸稳定、明显穿切变质岩片理等特征，为以压扭性为主的韧脆性变形，上盘向北西运动，构造岩以千枚岩或构造片岩为主。低角度断层是重要的储矿构造，其控制了矿体的形态、产状、规模和分布，其压扭性力学性质决定了交代为主的矿化蚀变类型，而且在成矿过程中也起到地球化学界面作用。

| Abstract: | The ore-controlling structure in Xiaoban gold deposit is a low-angle fault-detachment faultof north-western of Puyang metamorphic core complex, developing on the metamorphic structure. It is characterized by the flat occurrence, stable extension and frequent dissection to theschistosity of metamorphic rocks. It is a ductile-brittle compreso-shear deformation belt with itsupper side moving towards the western. The fault rocks in the lower-angle fault are mainlyphyllonite and tectoncaschist. The low-angle fault is the important impounding structure, whichcontrols over shape, occurrence, scale and distribution of the gold ore-body, and the dynamicpropelty of the compresso-shear constrains the mineralization alteration type. The ore-controlling structure also plays an important rule of geochemical interface in the gold mineralization. |
