| 摘 要： | 本溪盘岭地区铜、铅锌矿床类型主要有沉积－变质矿床、沉积－强烈改造矿床、沉积－变质 (改造 )－岩浆热液叠加矿床、后成矿床 4种类型。通过对矿床地质特征、沉积环境、沉积相、矿区构造等方面的研究，认为矿床 (化 )明显受沉积环境、地层的岩性、岩相的控制，并受构造岩浆活动的影响，成矿条件有 4种：矿床原始沉积条件；成矿物质来源条件；后期改造富集条件；成矿的物理场和地球化学场条件。通过成矿条件分析，本区海湾浅海环境的氧化－还原的环境是铜、铅锌有利的沉淀场所，富含有机质的薄层互层带是矿物赋存有利空间。

DISCUSSION ON METALLOGENIC CONDITIONS OF Cu,Pb Zn DEPOSITS IN PANLING AREA OF BENXI,LIAONING |
| |
| Abstract: | Cu,Pb Zn deposits in Panling area of Benxi mainly were divided into 4 types:sedimentary metamorphosed deposits,sedimentary strong reformed deposits,sedimentary metamorphosed(reformed)magmatic hydrothermal superimposed deposits and subsequent deposits. Analysis on geological characteristics of deposits,environment and facies of sedimentary and tectonics in the studied areas shew that the metallization of the Cu,Pb Zn deposits were obviously controlled by environment of sedimentary,lithology and phases of strata, and influenced by tectonomagmatic activities. There were 4 ore forming conditions:original sedimentary condition,sources condition of ore forming materials, subsequent reformed and enriching condition,ore forming physical field and geochemical condition.Through study on the ore forming conditions,oxidation reduction environments in gulf shallow sea were considered to be favourable to the sdimentary of Cu,Pb Zn, and thin interbedded belts rich in organic materials to be favourable to the occurring of ore forming materials. |
