攀枝花钒钛磁铁矿样品的钒同位素组成

本研究致力于探究层状侵入体的形成机制及其岩浆演化过程，样品取自中国西南部攀枝花层状侵入体的全岩及矿物分离体（斜长石和磁铁矿）。利用多收集器电感耦合等离子体质谱（MC-ICP-MS）测定全岩和矿物分离体的钒同位素数据。综合上述数据，旨在通过钒同位素视角揭示层状侵入体的岩浆起源、演化机制以及化学层状结构的形成过程，特别是探讨钒同位素分馏在岩浆分异和硅酸盐不混溶过程中的作用，从而为理解层状侵入体的成因提供新的证据和视角。This study aims to investigate the formation mechanism and magmatic evolution process of layered intrusions. Samples were collected from the whole rocks and mineral separates (plagioclase and magnetite) of the Panzhihua layered intrusion in southwest China. Vanadium isotope data of whole rocks and mineral separates were measured using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). By integrating these datasets, this study intends to reveal the magmatic origin, evolution mechanism and formation process of the chemical layered structure of layered intrusions from the perspective of vanadium isotopes, particularly exploring the role of vanadium isotope fractionation during magmatic differentiation and silicate immiscibility processes, so as to provide new evidence and perspectives for understanding the genesis of layered intrusions.
