| 摘 要： | 长江中下游地区是我国重要的硫铁矿产地之一 ,已探明的 47个矿床主要集中分布在宁芜、庐枞、铜陵、宁镇等 7个成矿区内。主要矿床可划分为 4种成矿类型 ,即陆相火山型、夕卡岩型、斑岩型及热液型。通过对硫铁矿成矿地质条件分析认为 ,陆相火山型、夕卡岩型硫铁矿床成矿规模大、分布集中 ,为今后找矿的主攻类型。在铜陵、宁芜、庐枞 3个成矿区可分别圈定出找矿有利地段。

| Abstract: | Along the middle and lower reaches of the Yangtze river, one of the most important pyrite producing areas in the country, 47 pyrite deposits have so far been proven, concentrating to seven metallogenic provinces including Nanjing Wuhu, Lujiang Zongyang, Tongling, Nanjing Zhenjiang, and so on. The leading deposits may be grouped into four types, namely, continental volcanic, skarn, porphyry and hydrothermal among which, according to analysis of mineralizing conditions, the former two types have larger sizes and concentrated distribution, thus probably regarded as preferred targets for deposit prospecting. Districts favorable for ore hunting can be mapped in three provinces of Nanjing Wuhu, Lujiang Zongyang and Tongling. |
