摘要
宣恩县滕家湾沉积型铅锌矿产于下奥陶统南津关组底部生物碎屑灰岩中,与生物化学作用有关,形成于开阔潮下带。含棕红色闪锌矿条带生物碎屑灰岩是最重要的找矿标志。与滕家湾铅锌矿相类似的矿点还有曾家垱、郑家、郭家坡、肖家湾、陆家坡5处,形成北东向铅锌矿化带,长20 km以上。铅锌矿化带中存在明显的Pb、Zn异常,具有较大的找矿潜力。
The sedimentary Tengjiawan lead-zinc deposit of Xuan＇en County of Hubei occurs within the Lower Ordovician bioclastic limestone of Nanjinguan Formation. It formed under an open tidal zone, with biochemistry activities. The outstanding indicator for ore-prospecting is the brown-red aphalerite- bearing banded bioclastic limestone. Other similar ore occurrences include： Zengjiadang, Zhengjia, Guojiapo, Xiaojiawan and Lujiapo spots in NE mineralization zone which extends more than 20 km. The ore zone correspondent to the optimal anomalous zone of lead and zinc in southwest Hubei. which means a huge potentiality for ore prospecting.
