红十井金矿大地构造位于塔里木陆壳板块由断裂控制的北山裂谷活动带。该区分布非常多的金矿床点,找矿潜力巨大。矿区内主要分布有两大类金矿,即蚀变岩、大青山式石英脉复合型和构造破碎蚀变岩型金矿床。该矿处于断裂活动多发且强烈的红十井断裂带上,其成矿的范围与规模受到由断裂派生的次级构造形成的构造断裂蚀变带的控制,成矿条件优越。文中在对红十井金矿地质特征进行分析的基础上,探讨该矿床成因,并总结其找矿标志,为今后区内找矿提供参考。 相似文献

滩北雪峰位于祁漫塔格地区西段,是利用化探手段新发现的构造蚀变岩型金矿,探讨该金矿的化探异常特征及其找矿前景,对在祁漫塔格地区寻找金矿具有重要指导意义。在滩北雪峰地区开展了1/1万土壤地球化学测量,结果显示Au为富集元素,变异系数较大,R型聚类分析显示Au与Bi呈显著正相关,表明该区金成矿可能与中低温热液活动有关。进一步分析元素地球化学特征,并结合矿区地质背景,圈定出13个土壤综合异常,选择AP7、AP9异常区开展了异常查证工作,发现1条金矿化蚀变带,带内圈定出3条金矿体,地表亦发现多处金矿化线索。结合成矿地质条件,初步建立了地质、地球化学和构造等方面的找矿标志,探讨了矿床成因,指出今后找矿方向。土壤地球化学研究表明:该区具有良好的找矿前景,是寻找构造蚀变岩型金矿的有利地区。 相似文献

研究区大地构造位置处于东昆仑与西秦岭衔接部位,经历了复杂的构造演化过程,出露地层主要为中—下三叠统隆务河群,中酸性岩浆岩发育,成矿地质条件优越,已发现显龙沟锑金矿、加吾金矿等矿床,但区内以前未发现有钨矿化。以1/5万水系沉积物测量原始数据为依据,对研究区内地质、地球化学特征及成矿条件进行分析,结合实际找矿工作,认为区内W、Au、Ag、As、Sb元素富集程度较高,在钨矿找矿方面具有很大潜力,指出有利找矿地段为隆务河群第二岩性段内钨异常分布区,赋矿岩性为中薄层砂岩及板岩段内厚大的中薄层砂岩夹层,矿化类型以蚀变岩型及石英脉型为主。 相似文献

结合步阴尾地区相关地质勘探成果,对该区成矿地质背景、矿区地质特征、矿床形成条件及成因进行了详细分析,研究表明:①金矿的形成经历了后期构造及岩浆岩多期多次的反复作用,其过程处于多期多次反复强烈的构造活动中;②发现的3个金矿化体全部产于矿区北东走向断层破碎带中,矿体完全受构造控制。矿石品位在1.47g/t~2.21g/t,厚度在2.07m~2.11m;③该矿床为破碎带蚀变岩型金矿床,金矿受断裂破碎蚀变带控制,矿体的形态、产状与断裂蚀变带一致,矿体成脉状、透镜状,有分支复合的现象。在上述分析的基础上,总结该区矿床成因及找矿标志,对于类似矿床找矿具有一定的参考价值。 相似文献
