| 中文摘要: |
| 安徽省地处华北陆块、秦岭-大别造山带和扬子陆块三个Ⅱ级构造单元的拼合部位，构造活动强烈，矿产资源较丰富。主要成矿作用有沉积作用、沉积变质作用、岩浆作用与风化作用等。省内地层从新太古界到第四系均有出露，沉积类型多样，伴随着沉积作用形成了丰富的煤、石煤、岩盐、石膏、铁、锰、硫、磷、重晶石矿床及铜、钼、银等矿化层；沉积变质作用形成了丰富的铁、锰、磷、菱镁矿床；岩浆活动强烈，金属矿床大都与燕山期中基性-中酸性侵入岩、浅成斑岩及中基性火山岩有关；与风化作用有关的矿化以砂金、锰、金红石、稀土、磷等为主。文章在安徽省矿产资源潜力评价项目研究的基础上，系统总结了省内主要矿床成矿作用特征，依据"全国矿床成矿系列"方案将全省矿产资源划分为21个成矿系列、31个成矿亚系列，并归并为5个成矿系列组合，其基本涵盖了省内目前已发现的所有金属矿产和部分非金属及化工矿产。对成矿亚系列进行了重点描述，其对深入研究安徽省区域成矿规律和指导矿产勘查工作具有参考意义。 |

| Lying in the juncture of three classⅡgeotectonic units (North China plate, Qinling-Dabie orogenic belt and Yangtze plate) Anhui Province is characterized by intense tectonic movements and rich mineral resources. The ore-forming process includes sedimentation, sedimentary metamorphism, magmatism and weathering; All strata From Neo-Archaeozoic to Quaternary are well developed and widely distributed. Abundant sedimentary ore deposits were found from different ages of strata, such as coal, stone coal, halite, gypsum, iron, manganese, sulfur, phosphorus, barite and mineralized layer of copper, molybdenum, argentums; Many of iron, manganese, phosphorus, magnesite are related to sedimentary metamorphism; In addition, magmatic activities were very strong, especially in Yanshan period. Many of metallic deposit are related to intermediate-mafic-intermediate-acid intrusions, hypabyssal porphyry and intermediate-mafic volcanicrocks; Placer gold, manganese, rutile, rare earth and phosphorus are related to weathering. Based on the assessment of mineral resource potential of Anhui Province, this paper summarizes the major mineralization characteristics; According to the academic thought of minerogenetic series in regional metallogeny (Chen, et al, 2006), 21 minerogenetic series and 31 minerogenetic sub-series are recognized here. Furthermore, they are classified to 5 series groups; Specifically, minerogenetic sub-series were mainly introduced. Almost all of the metallic ore deposits, part of non-metallic ore deposits and chemical mineral resources are included in such a classification of minerogenetic series. This classification is of far-reaching significance for studying the regional metallogenic regularity and mineral exploration in Anhui province. |
