| 摘 要： | 柳西地区自古生代以来形成的柳园－俞井子裂谷带等构造奠定了金矿床产出的地质背景、金矿成矿作用受一定的地层、构造、岩浆岩控制，不同级别和规模的构造分别控制着金矿成矿带、矿床（体）的产出，同时控制着金矿的矿床类型及成矿元素组合。找矿方向为柳园－俞井子裂谷带南北缘深大裂带及其内部次级大断裂两侧。

| Abstract: | Gold deposits in Liuxi area were formed under the background of Liuyan-Yujingzi rift zone which took shape since Paleozoic Era. Ore formation is controled by certain stratigraphic units, tectonics and magmatism. Tectonics or stractures in varied scales control ore belt, ore deposits(bodies) and ore deposit type and ore element assemblages respectively. The further exploration should be oriented to deep and large fractural zones in the south and north margins of the rift and the subscale fractures in itself. |
