    安徽北淮阳地区金成矿地质背景地质条件和成矿作用

    A STUDY ON GEOLOGICAL BACKGROUND,GEOLOGICAL CONDITIONS AND GOLD MINERALIZATION IN THE NORTH HUAIYANG REGION,ANHUI PROVINCE

    • 摘要: 安徽北淮阳地区位于大别山碰撞造山带北坡,其南北分别以磨子潭-桐城深断裂和金寨-舒城深断裂为界,向东被郯-庐断裂带截切。区内晚侏罗世火山岩带中发育一系列金矿床(点),可划分为浅成侵入热液型、次火山热液型和火山热液型三类金矿床。火山岩带基底为古元古界大别群杂岩和震旦系佛子岭群变质岩系,其原岩为基性火山-沉积岩建造,夹有大量镁铁质和超镁铁质岩块,含金丰度较高,为良好的原生矿源层。磨子潭-桐城深断裂对本区的地质构造发展、中生代岩浆作用及金成矿作用起着重要的控制作用。研究表明,本区晓天金矿田三种类型金矿床在垂向上可能具有"三层楼"结构分布特征,这对本区找矿方向将具有重要意义。

       

      Abstract: A series of gold deposits and spots occured in Late Jurassic volcanic rock zone of north Huaiyang region, Anhui province.They can be divided into three types:hypabyssal magmatic, subvolcanic and volcanic hydrothermal types,The zone located in north of Dabie collision orogenic belt bounded by the Mozitan-Tongcheng,the Jinzai-Shucheng deepseated fault in south and north respectively, with truncated by Tancheng-Lujiang fault zone in east and extends westwards into Henan province, The basement of the volcanic rock zone consists of Paleoproterozoic Dabie Group complex and Sinian Foziling Group. Their primary rocks are a suite of basic volcanic-sedimentary rock formation with the mafic-ultramafic rock as a primary mineral source bed of gold. The tectonic development, Mesozoic magmatism and gold-mineralization are controlled by the Mozitan-Tongcheng deep fault.The distribution of the three types gold deposits is characterized by vertical zonation, similar to a building with three storeys,which has important significance for exploration of the gold deposit in this area.
