摘要:
三山岛断裂带蚀变岩型金矿床控矿断裂产状变化部位含矿性存在差异,使得矿体不连续,勘查标识不明确。通过对三山岛北部海域金矿床30号勘探线的多个钻孔和三山岛井下坑道进行系统编录和样品采集,研究矿物共生组合与矿脉之间的穿切关系。研究表明:北部海域金矿床可划分为4个成矿阶段,即石英—黄铁矿—钾长石阶段(Ⅰ)、石英—黄铁矿—黄铜矿—自然金阶段(Ⅱ)、石英—黄铁矿—方铅矿—闪锌矿—自然金阶段(Ⅲ)和贫矿菱铁矿—方解石阶段(Ⅳ),其中Ⅱ和Ⅲ阶段是金的主要成矿阶段。利用短波红外光谱对控矿断裂含矿和贫矿部位样品进行分析,发现蚀变矿物组成、Al-OH吸收峰位和结晶度(IC)等存在明显差异,高的Pos2200和IC值与金矿体之间存在明确的正相关关系。对各钻孔的品位数据进行统计分析后,引入机器学习算法进行分析,强调IC值具有更高的权重影响。黄铁矿微量元素研究显示:As、Pb、Bi、Te和Sb等元素与Au元素含量之间具有显著正相关性。由此,基于断裂产状、短波红外光谱指标和黄铁矿元素含量等变化情况,建立了全新的勘查标识,对实际找矿勘查工作具有指导意义。
