Chemical analyses of Macquarie Island basaltic glasses and melt inclusions quantify volatile and metallic elements. The dataset likely contains major and trace element concentrations in weight percent and ppm, as well as radiogenic isotope ratios. Data were collected from Macquarie Island samples and analyzed using electron microprobes, FTIR spectroscopy, LA-ICP-MS, SIMS, and multicollector mass spectrometry.
Use Cases
- Modeling sulfur budgets during seafloor alteration based on sulfur and chlorine concentrations.
- Investigating fractional crystallization and degassing processes based on volatile and trace element distributions.
- Correlating ore-forming element systematics with the origin of seafloor massive sulfide deposits.
- Analyzing mantle melt evolution using radiogenic isotope ratios (Nd, Sr, Pb).
Strengths
- Analyses performed using state-of-art techniques including electron microprobes, FTIR spectroscopy, LA-ICP-MS, SIMS, and multicollector mass spectrometry.
- Data includes major petrogenetic elements, trace elements, and radiogenic isotope ratios, covering a wide range of geochemical parameters.
- Samples are from a specific, documented location (Macquarie Island) with references to published geological studies.
Limitations
- Row count is unknown, which may limit suitability assessment.
