基　　金：湖南祁阳地区铅锌多金属矿远景调查(编号:[2013]01-017-030);湖南省祁阳县戴家岭矿区铅锌矿普查(编号:20130524)资助

摘　　要：戴家岭矿区位于衡阳盆地西南缘铅锌多金属矿重点勘查区中部,成矿地质条件优越。本区铅锌矿体按赋存层位可划分为三类:第一类为赋存于主干断裂破碎带中的铅锌矿体;第二类为赋存于主干断裂破碎带下部次一级裂隙带中的铅锌矿体;第三类为推测的矽卡岩型铅锌矿体。主干断裂破碎带下部的次级裂隙带是本区主要容矿空间,下一步要将找矿重点放在主干断裂破碎带下部次级裂隙带中,厘清次级裂隙带中铅锌矿体的含矿层厚度,同时加大对矿区深部矽卡岩型矿体的探索,应用钻探结合井中磁测等物探方法进行综合勘查,以期取得找矿突破。本文主要根据近年来在该区开展的地质勘查工作中所取得的成果和认识,对该区今后的找矿方向及方法提出几点建议,为后期该区域的找矿工作提供参考和依据。Daijialing Pb-Zn deposit is located in the middle of Southwestern margin of Hengyang basin Pb-zn polymetallic belt. There are three types of lead-zinc mineralization in Daijialing： the first is the lead and zinc ore-bodies occurred in the main fractured zone; the second is the lead and zinc ore ore-bodies in the lower secondary fissure zone of the main fracture zone; the third is skarn-type lead and zinc ore-bodies. The secondary fissure zone in the lower part of the main fracture zone is the main storage space of the ore bodies in the area, the next step is to focus on the secondary fissure zone in the lower part of the main fracture zone. The thickness of the ore deposits of lead and zinc ore-bodies in the secondary fissure zone is clarified. At the same time, the exploration of the deep skarn type lead and zinc ore-bodies in mining area should be increased. Adopt drilling and borehole magnetic measurement etc. geophysical techniques can carry on for comprehensive exploration.
