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,伴随碱性火山喷发一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。
落因揹斜兩翼地層構造、地層巖相、含礦的差異性,證明揹斜軸部存在生長斷層。凡有長斷層齣現,因民組、落雪組巖相劇變,伴隨堿性火山噴髮一噴溢活動形成細碧巖、基性鎔巖、角礫巖之處成為成礦必要條件。

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.
