摘要
稀土矿物独居石、xenotime和allanite是严格意义上的稀土矿物,因为镧系元素(La…Lu)和钇是它们的关键成分。磷灰石不需要稀土元素,但由于磷灰石在许多岩石中含有大量的稀土元素,因此被列入本次评述。这四种矿物还含有异常高的放射性核素浓度,特别是Th和U,这构成了它们作为地球计时器的基础。这四种辅助矿物在岩石年代学中发挥着越来越重要的作用,因为它们提供了将可靠的现场年龄与岩石成因(P-T)条件联系起来的方法,从而可以为基于其他矿物的岩石成因年代学提供背景。本文的第一部分介绍了进行综合岩石年代学分析的基本条件。首先分析了四种稀土矿物的个体特征,即它们的晶体化学性质和稳定性关系。接着讨论了用于示踪岩石成因的温度计和微量元素地球化学,最后总结了它们的年代学。第二部分介绍了案例研究,以突出ree矿物的特定优势,用于解决从成岩到岩浆条件的广泛过程的动力学。最后,在最后的简短部分概述了当前的一些挑战和未来工作的前景。为了时髦地介绍四种稀土矿物,让我们回顾一下它们名字的由来。这三种磷酸盐都有受人尊敬的希腊祖先,而allanite则有坚实的苏格兰根源,但这四种磷酸盐在词源或类型材料上都表现出独特性。磷灰石长期以来一直困扰着博物学家,因为它表现出巨大的化学和物理变异性,并且与其他矿物相似。经过鉴定后,亚伯拉罕·戈特利布·沃纳将其命名为磷灰石。他的推理参考了希腊词根“πατ ο ω”,并给出了精确的拉丁语翻译:decipio。从字面上看,两者都意味着“我欺骗”或“我误导”,这听起来像是这种矿物对愚弄的恰当忏悔……
Petrochronology Based on REE-Minerals: Monazite, Allanite, Xenotime, Apatite
### REE-minerals
Monazite, xenotime, and allanite are REE1-minerals sensu stricto because lanthanides (La…Lu) and yttrium are critical constituents in them. Apatite does not require REE, but because it contains substantial REE in many rocks, it is included in this review. All four minerals also host unusually high radionuclide concentrations, notably Th and U, forming the basis of their utility as geochronometers.
This quartet of accessory minerals is playing an increasingly important role in petrochronology because they provide ways to link robust spot ages to petrogenetic ( P–T ) conditions so can lend petrogenetic context to chronology based on other minerals. Part I of this review assembles the basic requisites prior to integrative petrochronologic analysis. Individual characteristics of the four REE-minerals are addressed first, i.e., their crystal chemistry and stability relations. Thermobarometers and trace element geochemistry used for tracing petrogenesis are discussed next, and finally their chronology is summarized. Part II presents case studies to highlight the specific strengths of REE-minerals used to resolve the dynamics of a broad range of processes, from diagenetic to magmatic conditions. Finally, a brief section at the end outlines a few of the current challenges and promising perspectives for future work.
To introduce the four REE-minerals in style, let us recall the origins of their names. The three phosphates have well respected Greek grandparents, and allanite has solid Scottish roots, yet of all four of them show idiosyncracies in etymology or type material.
Apatite had long puzzled naturalists, as it shows great chemical and physical variability and can resemble other minerals. Once properly identified, Abraham Gottlieb Werner named it apatite. His reasoning referred to the Greek root ἀπατὰω and giving the precise Latin translation: decipio . Taken literally, both mean “I deceive” or “I mislead”, which sounds like an apt confession from this mineral for having fooled …
期刊介绍:
RiMG is a series of multi-authored, soft-bound volumes containing concise reviews of the literature and advances in theoretical and/or applied mineralogy, crystallography, petrology, and geochemistry. The content of each volume consists of fully developed text which can be used for self-study, research, or as a text-book for graduate-level courses. RiMG volumes are typically produced in conjunction with a short course but can also be published without a short course. The series is jointly published by the Mineralogical Society of America (MSA) and the Geochemical Society.
