Whole rock geochemical data from Arizona porphyry mineral systems (2024)

September 11, 2025

This report includes whole rock geochemical data from a newly collected suite of samples from igneous systems across Arizona. The data release includes samples collected in calendar year 2024 that support an ongoing, multi-year project dedicated to characterizing magmatic porphyry systems toward understanding possible basement influence on porphyry style mineralization. This preliminary dataset includes samples from basement host rocks, plutonic rocks, and associated mineralized/barren porphyries from across the state. The release includes two spreadsheets (as csv files). The first sheet (Whole Rock Data.csv) includes the sample identification information (i.e., sampling locations, mapped geologic units, rock type) as well as the results of major and trace element geochemical analysis determined by wavelength-dispersive X-ray fluorescence and inductively coupled plasma-optical emission spectroscopy, respectively. The second spreadsheet (Reporting Limits.csv) includes the reporting limit thresholds for each element and oxide weight percent that was measured by both analytical methods. Empty cells in the "Whole Rock Data.csv" spreadsheet indicate measurements fell above or below the respective reporting limit thresholds.
