| 摘 要： | 芦柴冲矿床位于滇东南砚山县境内，属南岭地区西南端－－滇东南早泥盆世的层控矿带。经野外调研和室内系统研究，发现矿床为典型非火山成因的、严格受沉积相（台盆相区）控制的海底喷流沉积成因矿床。矿床中发育的南北向同生扩张断裂是重要的控盆和控矿构造，是海底喷流成矿的含矿流体运移的通道，它具周期性的振荡运动的特点，导致海底喷流成矿具周期性的沉积旋回。

| Abstract: | The deposit located in Yanshan county of southeast Yunnan Province. It is part of early Devonian stratabound ore zone. A systematic study showed that the deposit was a typical unvolcanogenic,sedimentary facies-controlled exhalation sedimentary deposit. The south-north trending synsedimentary fault is an important basin and ore control structure, migrational channel of metaliferous fluids in exhalogene deposit. The mineralization process has characteristics by vibratory motion in periods and exhalative-sedimentary mineralization cycles. |
