STUDY OF STRONTIUM ISOTOPIC GEOCHEMICAL CHARACTERISTICS OF APATITE AND THEIR APPLICATIONS

An accurate determination has been made of the concentrations of rubidium and strontium of a number of apatites from different kinds of granitoid rocks in China on the mass spectrometer, and an intensive investigation has been carried out on the strontium isotopic geochemical characteristics of different kinds of apatite together with their applications in the study of petrogenesis, evolution of magma, division of rock belts, tectenic movements, isotopic geochronology, reconnaissance survey and ore prospecting, etc.     

磷灰石中锶同位素地球化学特征及其应用的研究

本文用质谱法精确地测定了我国各种类型花岗质岩石中若干磷灰石的Rb,Sr含量及Sr同位素组成;着重研究了各种磷灰石的Sr同位素地球化学特征及其在岩石成因、岩浆演化、岩带划分、构造运动、同位素地质年代学以及普查找矿等方面的应用。
