TSG files contain PLS-scalars applied to the Eucla Basement hyperspectral drill core data

GSWA collected hyperspectral reflectance spectra from drill holes intersecting the Eucla Basement (FOR004, FOR010, FOR011, MAD002, MAD014, HDDH001) using a HyLogger3 located at GSWA’s drill core library in Carlisle, WA. A PLS-based approach was used to model three geochemical indices, including the Magnesium number (“Mg#”; Mg/(Mg+Fe)), Silica Calcium Iron Magnesium number (“SCFM”; SiO2/(SiO2+CaO+FeOtot+MgO)), and Aluminium saturation index (“ASI”; Al2O3/(Na2O+K2O+CaO)) from the hyperspectral data. The accompanying CSIRO report EP184011 provides a detailed description of applied processing methods using The Spectral Geologist (TSG) software, including the feature extraction scripts (base and Multiple Feature Extraction Method (MFEM) scripts), and Partial Least Squares (PLS) modelling of geochemistry. \nLineage: In the frame of AuScope's NVCL Infrastructure Program and GSWA's EIS Program, hyperspectral reflectance spectra were collected by GSWA from drill holes FOR004, FOR010, FOR011, MAD002, MAD014 and HDDH001 using a HyLogger3 located at GSWA’s drill core library in Carlisle, WA. The HyLogger3 data were processed further CSIRO using The Spectral Geologist software (TSG).

西澳大利亚地质调查局（GSWA）利用位于西澳大利亚州卡莱尔市其岩心库中的HyLogger3设备，采集了穿越尤克拉基底（Eucla Basement）的钻孔（FOR004、FOR010、FOR011、MAD002、MAD014、HDDH001）的高光谱反射光谱。研究采用基于偏最小二乘（PLS）的方法，利用高光谱数据对三个地球化学指数进行建模，包括镁指数（"Mg#"；Mg/(Mg+Fe)）、硅钙铁镁指数（"SCFM"；SiO₂/(SiO₂+CaO+FeOtot+MgO)）和铝饱和指数（"ASI"；Al₂O₃/(Na₂O+K₂O+CaO)）。随附的澳大利亚联邦科学与工业研究组织（CSIRO）报告EP184011详细描述了使用光谱地质学家（The Spectral Geologist，TSG）软件的应用处理方法，包括特征提取脚本（基础脚本和多特征提取方法（MFEM）脚本）以及地球化学的偏最小二乘（PLS）建模。
