摘要:
红外光谱可有效识别与成矿有关的中低温指示矿物,在野外利用红外光谱仪器开展矿物填图是目前国内外找矿勘查工作中广泛应用的一项高新技术,具有采样密度高、数据量大、效率高、成本低等优势。文章重点介绍了国内外红外光谱仪器研发历史及现状,以及近年来运用国产CMS350A型全自动数字化岩芯扫描仪开展的矿物填图范例,较全面地展示矿物填图技术及其应用效果。红外光谱矿物填图技术基于海量数据客观勾绘矿化蚀变特征,精准识别具有重要找矿意义的蚀变矿物,获取矿物离子交换信息并反演热液流体性质,为区域找矿潜力评价及下一步找矿部署提供指导。红外光谱矿物填图技术的发展方向为工作波段向热红外扩展、设备小型化、提高光谱分辨率及拓展应用领域。
Abstract:
As an effective indicator for low-middle temperature minerals related to mineralization, infrared spectrum has been extensively employed in-site mineral mapping. This high technology is characterized by high sampling density, large data volume, high efficiency and low cost. With an emphasis on introduction to the latest development and status of infrared spectroscopy instrument and application of Domestic CMS350A digital core scanner, this study presents application of the technique and its results. On the basis of mineralization and alteration features outlined by mass data, the study precisely indentified altered minerals which are significant to prospecting, obtained ion exchange data of minerals and deduced the properties of hydrothemal fluid, providing guidance for potential evaluation of regional prospecting and further deployment for mineral exploration. Thus, the study direction of infrared spectrum mineral mapping technology should focus on the outreach of working band toward thermal infrared, miniaturization of equipment, improvement of spectral resolution and expansion of applicable fields, etc.
