Test Data of Yalongri Porphyry Cu-W Deposit, Xizang (Tibet)
Description
These two supplementary datasets support the mineralization analysis of the Yalongri porphyry Cu-W polymetallic deposit in the Gangdese Metallogenic Belt, Tibet. Supplementary Data S1 contains whole-rock geochemical test results of surficial rocks, including sampling location coordinates (X, Y, elevation H), unique sample numbers (e.g., YP01-01), and measured values of ore-forming elements (Cu, W, Au, Ag, Pb, Zn, Mo). This dataset is used to analyze the spatial distribution of mineralized elements, delineate mineralization anomalies, and evaluate the ore-forming potential of the deposit. Supplementary Data S2 consists of three worksheets: the "SWIR" worksheet provides short-wave infrared spectral data (sample IDs, coordinates, mineral characteristic absorption peak parameters, and mineral identifications like chlorite "chl" and epidote "ep"); the "TIR" worksheet includes thermal infrared spectral data for high-temperature mineral phase recognition; and the "Drill hole" worksheet contains drill core spectral data. This spectral dataset helps identify characteristic minerals in ores, invert the activity intensity of ore-forming fluids, and establish a vertical spectral-mineralization relationship model by comparing surface and drill core data. Together, the two datasets form a complete "geochemistry + spectroscopy" data chain, meeting the reproducibility requirements of academic journals and supporting the integrated research methodology of SWIR-TIR spectroscopy and element geochemistry.

Steps to reproduce
Field sampling: Collect surface rock and drill core samples from the Yalongri porphyry Cu-W polymetallic deposit, record geographic coordinates (X, Y, elevation) and unique sample numbers for each specimen. Whole-rock geochemical test: Analyze concentrations of Cu, W, Au, Ag, Pb, Zn, Mo elements by standard geochemical analytical procedures to obtain the dataset in Supplementary Data S1. Spectral measurement: Test short-wave infrared (SWIR) and thermal infrared (TIR) spectra of rock samples using mineral spectral instruments, extract mineral absorption feature parameters of chlorite, epidote and other alteration minerals to generate spectral data in Supplementary Data S2. Data sorting: Organize all geochemical and spectral test results into two Excel files, classify SWIR, TIR and drill core spectral data into separate worksheets, and label all sampling information and test indicators uniformly for secondary analysis with software such as TSG and RW.
