摘　　要：磷灰石广泛分布于各类岩石和矿床中,具有高度的稳定性和不易受到风化和蚀变的影响。这一特性使得磷灰石能够有效地记录和保留岩浆和热液活动的原始信息,被视为一种非常理想的常用示踪矿物。该文在总结前人对磷灰石研究成果的基础上,重点对磷灰石在矿床学领域被用来研究各种各样的科学问题的梳理和分析。本文综述了磷灰石在矿床学研究中的主要应用方向为:磷灰石中因富集多种重要微量元素,成为了解决地质年代问题的关键矿物;同时磷灰石是交代作用过程的指纹和岩石圈地幔流体流动记录仪,也是示踪成矿岩浆和热液流体来源及划分岩石和矿床类型的理想探针。因此开展磷灰石的原位地球化学分析为揭示矿床学研究具有重要的指示意义。Apatite is widely distributed in various rocks and deposits,which has high stability and is not susceptible to weathering and alteration.This property allows apatite to effectively record and retain the original information of magmatic and hydrothermal activity,and is regarded as a very ideal common tracer mineral.On the basis of summarizing the previous research results on apatite,this paper focuses on sorting out and analyzing various scientific problems that apatite has been used to study in the field of mineral deposit science.The main application directions of apatite in mineral deposit research are summarized as follows:Apatite has become the key mineral to solve the geological age problem because of its enrichment of many important trace elements;Apatite is the fingerprint of metasomatism process and the recorder of fluid flow in the lithosphere mantle.It is also an ideal probe for tracing the source of metallogenic magma and hydrothermal fluid and classifying the types of rocks and ore deposits.Therefore,in situ geochemical analysis of apatite is of great significance for revealing genesis of mineral deposit.
