【摘要】 湘东北地区已知规模较大的金矿床主要为石英脉带型。目前构造蚀变岩型金矿床较少,因此有关此类矿床构造地球化学成矿模型的研究甚少。文章选取区内规模最大的构造蚀变岩型金矿床——正冲金矿为研究对象,从微量元素特征入手,分析其元素相关性、地球化学参数及组合参数特征。类比已有构造叠加晕模型,总结出该区的构造地球化学成矿模型具多期多阶段性,将此认识应用于矿体的深部找矿预测,取得了较好效果。更多还原

【Abstract】 The main types of large scale gold deposits are quartz veinlets in Northeast Hunan.At present,tectonic alteration rock type gold deposits are rarely found,there are few studies on structural geochemical metallogenic models of tectonic alteration rock type gold deposits.In this study,the researchers were selected the largest tectonic alteration rock type gold deposit of Zheng Chong gold ore-body as the research object in the region.The characteristics of trace elements were studied,and element correlation,geochemical parameters and combination parameters were analyzed,Analogy analysis other existing constructed stacking halo models,and The structural geochemical metallogenic model has multiple periods and stages this area.It is applied to the prediction of deep prospecting and has good prospecting results.更多还原
