| 摘 要： | 落因背斜两翼地层构造、地层岩相、含矿的差异性,证明背斜轴部存在生长断层。凡有长断层出现,因民组、落雪组岩相剧变,伴随碱性火山喷发-喷溢活动形成细碧岩、基性熔岩、角砾岩之处成为成矿必要条件。

| 关 键 词： | 裂谷早期 裂堑盆地 生长断层 碱基性火山喷发 喷溢热水沉积成矿 |

| Abstract: | The differences in strata, structure, rock facies and ore - bearing of two limbs of Luo - Yin anti- cline prove that there is the fauh in the anticlinal axis. The necessary conditions of metallogenesis are appearance of growth fault; intense variation of Yinmin Formation, Luoxue Formation rock facies; the places of forming spilite, basic lava, breccia. |

| Keywords: | Earlier Period of Rift Graben Basin Growth Fault Alkaline - Basic Volcanic Eruption Ef-fusive Hydrothermal Sedimentary Metallogenesis |
