1）数据内容：本次数据是关于甲玛矿区典型钻孔（含3000m深钻）的热红外和短波红外光谱数据报告，是对甲玛斑岩成矿系统典型剖面的系统高光谱测量数据。2）数据来源及加工：数据来源野外一线仪器的直接测量。其中，短波红外波谱数据采用美国ASD公司生产的FieldSpec4光谱仪进行测量，热红外波谱测量使用美国Agilent 4300热红外波谱仪。3）数据质量评述：其中，光谱数据测量均按照设计要求开展，并采用The Spectral Geologist™（TSG光谱地质专家）分析软件结合镜下鉴定分析处理。4）数据应用成果及前景：甲玛矿区高光谱数据是对甲玛厚大矽卡岩矿体光谱数据的系统总结，建立了典型的光谱勘查模型，有助于运用于类似矽卡岩矿床的勘查和评价。

1) Data Content: This dataset is a report on thermal infrared and short-wave infrared spectral data from typical drill holes (including a 3000m deep drill hole) in the Jiama Mining Area, and constitutes systematic hyperspectral measurement data collected from the typical section of the Jiama porphyry metallogenic system. 2) Data Source and Processing: The data were obtained via direct field measurements using on-site instruments. Specifically, short-wave infrared spectral data were collected with a FieldSpec4 spectrometer manufactured by American ASD Inc., while thermal infrared spectral measurements were conducted using an Agilent 4300 thermal infrared spectrometer. 3) Data Quality Assessment: All spectral data measurements were conducted in strict accordance with the design requirements, and were analyzed and processed using The Spectral Geologist™ (TSG) analytical software combined with thin-section identification. 4) Data Application Achievements and Prospects: The hyperspectral data from the Jiama Mining Area is a systematic summary of the spectral data of the thick and large skarn orebodies in Jiama, and a typical spectral exploration model has been established, which can facilitate the exploration and evaluation of similar skarn deposits.
