湖南邵东县石桥铺铅锌矿是产于岩体构造破碎带中，属中—低温热液裂隙充填型矿床，位于关帝庙穹窿内，成矿时代为新华夏系。目前该矿区的一号断裂带、四号断裂带和九号断裂带中的局部地段发现有铅锌矿体和矿化体。岩浆期后的断裂带为后期矿体的形成提供了有利的矿液运移通道和储矿空间；新华夏系断裂控制着本矿区内矿体的形态、大小、产状等，是矿区内的主要控矿、容矿构造。且矿体具有明显的垂直分带特征，上部主要为萤石矿、重晶石矿，中、下部为铅锌矿。本文根据矿体地质特征、变化规律，分析矿床成因，总结找矿标志，为矿区找矿前景进行探讨和分析，为外围找矿提供思路。
湖南邵東縣石橋鋪鉛鋅礦是產于巖體構造破碎帶中，屬中—低溫熱液裂隙充填型礦床，位于關帝廟穹窿內，成礦時代為新華夏繫。目前該礦區的一號斷裂帶、四號斷裂帶和九號斷裂帶中的跼部地段髮現有鉛鋅礦體和礦化體。巖漿期後的斷裂帶為後期礦體的形成提供瞭有利的礦液運移通道和儲礦空間；新華夏繫斷裂控製著本礦區內礦體的形態、大小、產狀等，是礦區內的主要控礦、容礦構造。且礦體具有明顯的垂直分帶特徵，上部主要為螢石礦、重晶石礦，中、下部為鉛鋅礦。本文根據礦體地質特徵、變化規律，分析礦床成因，總結找礦標誌，為礦區找礦前景進行探討和分析，為外圍找礦提供思路。

The lead-zinc deposit in the Shiqiaopu, Shaodong County, Hunan is a structure controlled meso- and epi-hydrothermal fissure filling type of lead-zinc mine and occur in an intrusion, which is located in the Guandimiao dome and formed in the Neocathaysian. The lead-zinc ore and mineralization bodies have been discovered in local sections of the NO.1, NO.4 and NO.9 fault belts in the deposit area. Post-magmatism fault belts provide favorable channel for the migration of ore-bearing solutions and ore-accumulating space for the late stage ore bodies. The neocathaysian faults control the shape, scale and occurrence of the ore bodies and are the mian ore-controlling and ore-hosting structures. The ore bodies have obvious vertical zoning with fluorite and barite deposits in the upper and lead-zinc deposits in the lower. Based on the geological characteristics and the change regulation of ore bodies, analyses the genesis of mineral deposit, sum marizes the criteria for ore prospecting and discuss the prospecting potential , in order to provide ideas for prospecting on the periphery of this mineralized ifeld.
