通过对禄丰-武定地区成矿地质背景、成矿物质来源、成矿过程调查及与东川式铁铜多金属成矿条件对比研究，进一步阐明禄武地区是一个东川式铁铜多金属矿床的成矿集中区域，其成矿物质大部分来自于地球深部幔源，与火山岩浆活动有关，少部分来自于下伏地层和海盆地。成因总的归结为同生喷流热水沉积加改造。稀矿山式、落雪式、桃园式三种类型的矿床构成了本区域昆阳群褶皱基底层中一个完整的火山期后海相热液喷流、热水沉积-改造型成矿系列。这对禄武地区铁铜多金属成矿带找矿具有重要意义，也对丰富完善该区铁铜多金属矿床的研究和形成机制具有借鉴作用。

Based on the investigation of ore-forming geological background, ore material source and metallogenic process of Lufeng-Wuding area in comparison with the metallogenic conditions of the Dongchuan type iron-copper polymetallic deposits, the authors further prove that the Lufeng-Wuding area is a concentration area of Dongchuan type iron-copper polymetallic deposits, that the ore materials were mostly derived from the mantle source in the interior of the earth in relation to magmatic activity, with a minor part derived from the underlying strata and sea basin, and that the ore deposits resulted from syngenetic exhalative hydrothermal deposition with the addition of late reformation. Three types of ore deposits, i.e., Xikuangshan type, Luoxue type and Taoyuan type, constitute a complete post-volcanic marine hydrothermal spout, hot-water deposition-reformation style metal-logenic series in the folded basement bed within this region. The results obtained by the authors are of impor-tant significance for ore-prospecting work in iron-copper polymetallic ore-forming belt of Lufeng-Wuding area and also provide the reference for enrichment and improvement of the study of the metallogenic mechanism of iron-copper polymetallic deposits in this area.
