LA-ICP-MS data from Dorado (2024) - PhD Thesis

The dataset contains trace elements raw data of glass, plagioclases, feldspars and clinopyroxenes from the active Teide-Pico Viejo volcanic complex, obtained using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) at the Peter Hooper GeoAnalytical Lab, Washington State University.

Analyses were performed using an Agilent 7700 Series ICP-MS coupled with a New Wave UP-213 laser ablation system. A 30 μm laser spot size was used with a beam energy of ~10.6 J/cm³ at 20 Hz. Feldspar and glass analyses were conducted along transects parallel to crystal faces to minimise potential mixing between chemical zones, with track lengths varying from 100 to 500 μm depending on crystal size. Due to their smaller size, clinopyroxenes were analysed using spot analyses only. Data were normalised to the NIST 610 standard, using ²⁹Si as an internal reference, and the BCR-2 standard was used for external calibration. Analyses showing clear evidence of contamination from inclusions or microlites were excluded.

This dataset is structured by analytical session, with separate files provided for each session to maintain data reproducibility. Information about the samples can be found in Dorado (2024).
