摘　　要：长江中下游七大矿集区之一的庐枞矿集区矿产资源丰富,拥有多个大中型矿床,是我国重要的铁、铜、铅锌矿产区。本文在综合前人研究成果的基础上论述了庐枞矿集区内矿床的分布规律及其控矿构造。区内断裂构造和火山构造极为发育,是区内最重要的控矿构造。其中断裂构造是以基底NE向主干断裂和一系列与其平行的断裂为主导,与其他多个方向断裂组成复杂断裂网,为矿浆提供涌流通道和储矿空间;庐枞矿集区本身为一负向火山岩盆地,区内火山机构分布广泛,众多火山机构周围分布着环状断裂及放射状断裂,是成矿的有利部位。Luzong ore concentration area is one of the seven ore concentration area in middle-lower reaches of the Yangtze River region, which is rich in mineral resources and has many medium-sized deposit. It＇s an important producing areas of iron, copper, lead and zinc in China. This paper discusses the deposit distribution regularity and the ore-controlling structure of Luzong ore concentration area on the basis of previous research. Fault structure and volcanic tectonic are the most important ore-controlling structure of Luzong ore concentration area. The NE-trending main fault with series parallel sub-faults and different trending faults make up a fault system, which supply the migration channel for lfuids and provide the space for ore accumulation. Luzong ore concentration aera is a negative volcanic basin with much volcanic apparatus. The ring and radiant fractures around the volcanic apparatus become the favorable position for ore formation.
