通过测定矿物中元素H ,C ,O和S的同位素比值 ,认识矿物体系中的同位素效应 ,不仅能够确定矿物之间和矿物与流体之间的同位素平衡关系 ,而且能够了解影响矿物平衡和动力学同位素性质的因素。文中评述了稳定同位素分馏系数校准的理论计算、实验测定和经验估计方法 ,讨论温度、压力、化学成分和晶体结构等对矿物同位素性质的影响。由于同位素效应取决于矿物的物理和化学性质 ,因此应用稳定同位素来作为示踪剂不仅能够追索各种矿物学反应的路径 ,而且能够提供证据来阐明矿物晶体结构的某些细节。
By measuring the isotopic ratios of elements H, C, O, and S in minerals, understanding isotope effects in mineral systems can not only determine the isotopic balance between minerals and minerals and fluids, but also understand the effects of mineral balance and kinetics Isotopic nature of the factors. In this paper, theoretical calculations, experimental measurements and empirical estimation methods for the calibration of stable isotope fractionation coefficients are reviewed. The effects of temperature, pressure, chemical composition and crystal structure on the mineral isotopic properties are discussed. Because isotope effects depend on the physical and chemical properties of the minerals, the use of stable isotopes as tracers not only recapitles the pathways of various mineralogical reactions but also provides evidence to elucidate some details of the crystalline structure of minerals.
