About this Research Topic
This Research Topic aims to underscore (1) advances in the understanding of isotopic and trace element signatures in accessory minerals, notably zircon, apatite, titanite, and monazite as they pertain to magmatic evolution in fertile and barren terranes; and (2) textural and petrological factors affecting accessory mineral compositions that may lead to indeterminate classification of plutonic suites and incorrect assessment of magmatic fertility. The Research Topic will provide useful guides on how to successfully apply accessory mineral geochemistry in assessing intrusion-centered magmatic-hydrothermal systems as well as develop some novel geochemical classifiers/tools, with the compilation of accessory mineral composition data and application of machine learning methods.
Submissions underlining accessory minerals (e.g., zircon, apatite, titanite, and monazite) from intrusion-centered magmatic-hydrothermal systems (e.g., porphyry and skarn deposits) are welcomed. Key themes include, but are not limited to:
• In-situ analysis of isotopic, major, and trace elements in accessory minerals
• Geochemical mapping of accessory minerals to identify the compositional variation within accessory minerals
• Contrasts of accessory minerals of magmatic and hydrothermal origin and their roles in explaining magmatic-hydrothermal systems
• New accessory mineral-based geochemical tools through the combination of machine-learning and other statistical approaches
Keywords: accessory mineral, fertility, oxygen fugacity, granite, zircon, apatite, titanite, porphyry, skarn, mineral exploration
