随着原位微区分析技术的发展,金红石作为常见的副矿物,受到越来越多的关注。结合目前地学研究的热点科学问题,文中总结了金红石在变质岩石学中研究进展及存在的问题:(1)金红石在变质岩中的产状及形成过程;(2)金红石Zr含量温度计的进展及在低级、中级及高级变质岩中的应用;(3)金红石微量元素在弧岩浆过程和俯冲带变质作用的行为;(4)金红石U-Pb定年在变质岩中的应用。以上4个方面的研究一直是国内外的研究热点,结合对中国几条著名的俯冲带的深入研究,将会在有关金红石的变质岩石学研究方面取得更多的优秀成果。
Rutile is a very common accessary mineral in metamorphic rocks.Its geochemical characteristics attract more and more researchers along with the development of in-situ analysis method.This paper aims to provide an overview of the applications of rutile in metamorphic petrology,based on a review of data published in recent years.The focus lies on the following progress and some problems in the study of rutile in metamorphic rocks:(1) rutile occurrences and the reactions by which rutile grew in metamorphic rocks;(2) Zr-in-rutile applications in metamorphic rocks;(3) the role of rutile in arc volcanic process and subduction metamorphism;and(4) rutile U-Pb geochronology application in metamorphic rocks.Combined with the study of unique paleo-subduction zones in China,great interest will be focused on the research of rutile application in metamorphic petrology.
