Shortwave infrared (SWIR) data of hydrothermal alteration from the island of Milos, Greece (NERC Grant NE/L002434/1)

This dataset provides an overview of hydrothermal alteration samples from the island of Milos, Greece, that were analysed using a portable infrared mineral analyser (PIMA) or AgriSpec spectrometer. During data acquisition, spectrums were input into The Spectral Geologist (TSG) to provide an instant and estimated mineral identification using the shortwave infrared (SWIR) part of the electromagnetic spectrum. The samples were acquired during field visits between 2017 - 2019 by the British Geological Survey and the GW4+ Doctorial Training Partnership (NE/L002434/1). This data was primarily used to aid sample collection for further hydrothermal alteration analyses to improve our understanding of regional and local paleo-hydrothermal activity across the island. Identification by the TSG provides an estimation only, and the raw data files in .txt, .fos and .csv formats, are supplied for each analysis in the attached zipped file. This may be useful within the metallic and industrial mineral mining sector and associated researchers. The data includes grid references (± 5 m), TSG interpretations, and field/sample observations noted during data acquisition. GW4+ Doctoral Training Partnership (NE/L002434/1) is supported by grant award GA/09F/139 – RMS E3557, and the British Geological Survey’s University Funding Initiative (BUFI S345).

本数据集概述了希腊米尔奥斯岛上经便携式红外矿物分析仪（PIMA）或AgriSpec光谱仪分析的 hydrothermal alteration 样品。在数据采集过程中，光谱数据被输入至 The Spectral Geologist（TSG）系统，利用电磁波谱中的短波红外（SWIR）部分，以实现矿物识别的即时与估计。样品采集于2017至2019年间，由英国地质调查局（British Geological Survey）与GW4+博士培训伙伴关系（NE/L002434/1）在实地考察中进行。此数据集主要被用于辅助样本收集，以进一步进行 hydrothermal alteration 分析，从而深化我们对岛屿区域及局部古水热活动的理解。TSG 的识别仅提供估算，所提供的原始数据文件，包括 .txt、.fos 和 .csv 格式，均附于所附压缩文件中，供每次分析使用。这些数据可能对金属和工业矿物采矿行业及其相关研究人员具有实际应用价值。数据集包含网格参考（±5米）、TSG 解释以及数据采集过程中的现场/样本观测记录。GW4+博士培训伙伴关系（NE/L002434/1）由资助项目GA/09F/139 – RMS E3557支持，并得到英国地质调查局大学资助计划（BUFI S345）的支持。
