Abstract

Abstract

Biotite is not only a robust ⁴⁰Ar-³⁹Ar geochronometer, but also commonly used to constrain the physico-chemical conditions, magma source and evolution process, mineralization potential and tectonic settings of the parental magma. In this study, we have obtained the ⁴⁰Ar-³⁹Ar age and major element compositions of biotite from the most widely outcropped aegirine-nepheline syenite of the Saima alkaline complex. We further discuss the physicochemical property, the evolution process and tectonic settings of the rock by the combination of equilibrium calculation using pMELTS software on previously reported data. The biotite crystals from the aegirine-nepheline syenite have high Fe and Ti contents and belong to annite in both the APSE classification diagram and Mg-(Fe³⁺+Al^Ⅵ+Ti)-(Fe²⁺+Mn) diagram for biotite. On the basis of the major element compositions of the biotite, the crystallization temperatures and oxygen fugacity (lgf_O2) are estimated to range from 770 to 800℃ and -16 to -14, respectively, while the equilibrium calculation by pMELTS indicates that the magmatic system crystallized at >1 300℃ and the oxygen fugacity have decreased since the crystallization begun. The high temperature and decreasing oxygen fugacity prevent the early exsolution of a fluid phase, and the alkalis and volatiles are therefore retained in the melt and finally enriched in the hydrothermal fluids related to the late sodic lujavrite. Some of the biotite plates show oscillatory zoning, high TiO₂, Na₂O but low SiO₂ contents and low Fe³⁺/(Fe³⁺+Fe²⁺) ratio from the core to the rim, further indicating that the residual magmas after biotite crystallization would have lower temperature, lower oxygen fugacity but higher alkalis contents. The Saima alkaline complex is part of the E-W-trending alkaline rock belt at the northern margin of the NCC, and it is formed at~222 Ma as indicated by biotite ⁴⁰Ar-³⁹Ar age in post-collisional extension tectonic settings after the closure of the palaeo-Asian Ocean.
