摘要
枞阳县安凤地区铜矿位于长江中下游铁、铜、金(硫)成矿带中段,庐枞火山岩盆地矿集区西南部,成矿潜力较大。本文通过对区域地质背景、矿区及矿床地质特征等方面的综合分析,认为矿体主要赋存在安山玢岩、粗面安山岩、粉砂岩及蚀变凝灰质粉砂岩中,呈透镜状;矿床成因属与次火山岩有成因联系的低温热液充填矿床。
With great metallogenic potential,the copper deposits in Anfeng Area of Zongyang County are located in the middle section of iron,copper and gold(sulfur)metallogenic belt in the lower Yangtze valley and in the southwest of Luzong volcanic basin ore concentration area.Based on the comprehensive study and analysis of the regional geological background and geological features of the mining area and the deposit,this paper concluded that The ore bodies are lenticular and mainly exist in andesitic porphyrite,trachyte andesite,siltstone and altered tuffaceous siltstone.The genesis of deposits is a low temperature hydrothermal filling deposit which has genetic connection with subvolcanic rocks.
