摘　　要：锆石是岩浆岩、变质岩、沉积岩和月岩中最重要的副矿物。本文分别从锆石的形态、以及影响锆石形态的因素、锆石的主量、微量、稀土元素地球化学和氧同位素特征等方面进行系统综述。同时 ,论述了目前国内外有关锆石U Pb法定年的研究进展 。Zircon is one of the most important accessory minerals in igneous rocks, metamorphic rocks, sedimentary rocks and lunar rocks. The paper deals with the morphology,major element,trace element and rare earth element geochemistry and oxygen isotopes of zircons.Advances in various U Pb dating methods including thermal ionization techniques, sensitive high resolution ion microprobe, evaporation techniques, laser probe inductively coupled plasma mass spectrometry and electron microprobe are reviewed,and the applicability and limitation of the above dating method are also presented in this paper.
