摘　　要：湘西地区脉状钨锑金矿床矿体严格受构造控制,并普遍具有沿倾向发育较深、侧伏和板柱状赋存的规律。文章阐述了矿体侧伏的控制因素,并以沃溪金矿和泥潭冲金矿为例,分析了褶皱和断裂控制的板柱状矿床(体)的构造特点,总结了矿体板柱状赋存的成因以及矿体侧伏和板柱状赋存的规律,认为应该利用矿体的侧伏和板柱状赋存的规律指导勘查工作。Ore bodies of the vein-like W-Sb-Au deposits in western Hunan are strictly controlled by structure, and extend tabularly to more depth along dip. This paper elaborates control factor of pitch of the ore bodies in case of Woxi and Nitanchong gold deposits and analyses characteristics of fold or fault control on the deposit and tabular ore bodies and summarizes genesis of the extension and pitch pattern to guide further exploration.
