摘　　要：湘中响涛源-祖塔锰矿带位于湖南省桃江县、安化县、宁乡县境内,呈近东西向分布.长约近20 km,含矿岩系出露长度达50 km,矿带从南往北可分为6个含矿段,分别是木鱼山矿段、南石冲矿段、斗笠山矿段,黑油洞矿段、毛腊矿段、月山铺矿段和祖塔矿段.成矿带受控于桃江成锰沉积盆地中的同生沉积NNW向断裂带.锰矿的最佳富集区为盆地中心亚相的黑色页岩夹碳酸锰矿微相.岩性组合为黑色页岩、含锰碳酸盐岩及粘土岩.为一热水成因矿床.冲天腊烛向斜一带具有良好的成矿条件及找矿前景.Xiangtaoyuan-Zuta Manganese metallogenic Belt extending in EW direction in Central Hunan Province is located in Taojiang, Anhua and Ningxiang Area. The length is nearly 20 km long with the ore-bearing rock series exposed up to 50 km long, and the ore belt from south to north is divided into six ore section, namely Muyushan ore block, Nanshichong ore block,Doulishan ore block, Heiyoudong ore block,Maola ore block, Yueshanpu ore block and Zuta ore block. The metallogenic belt is controlled by the NNW-trending synsedimentary faults in the manganese-bearing basin of Taojiang. The optimal enrichment area of manganese ore is in black shale-manganese carbonate microfacies. The lithology is composed of black shale, manganese carbonate and clay rock. It is a hydrothermal deposit. It has favorable conditions for manganese mineralization and prospecting prospects in the syncline area of Lazhu, Chongtian.
