摘要
文章论述了垭都-蟒硐铅锌成矿带成矿地质条件,断层控岩、控矿特点。从区域地质地球化学背景、典型矿床产出特征,总结了垭都-蟒硐断裂带铅锌成矿规律。找矿实践证明,垭都-蟒硐断裂带内铅锌矿体主要呈陡脉状产出,旁侧次级断裂带中则呈层状产出;断层活动强度与铅锌矿化常成正相关关系;成矿地质条件、物化探异常特点、铅锌矿化富集特征显示,垭都、筲箕湾、羊角厂矿区深部及外围具备寻找大型铅锌矿床的潜力。
This paper discussed the geology and metallogeny of lead - zinc mineralization in the YaDu - - MangDong metallogenic belt. Based on re-gional geological and geochemical background and characters of known typical deposits and occurrences in the region, the lead - zinc mineralization rules are summarized. The exploration in the region shows that faults in the YaDu - - MangDong lead - zinc mineralization belt are the main ore-controlling structures, ore - bodies in major fractures are mainly occurred as steeply dipping veins, whereas and ore - bodies in nearby subsidiary fractures are mainly stratiform. The fault activity strength is positively related with the lead - zinc mineralization intensity. The geology, geophysical and geochemical anomalies and mineralization concentration rules all suggested that there are exploration potentials for discovering large lead - zinc deposits in the deeper section of the YaDu, ShaoJiWan and YangJueChang mining areas and also peripheral areas of the mines.
