摘要

钨矿的成矿年代学是该类矿床的重点研究课题之一

其成矿年龄测定方法包括直接测定和间接测定。原理主要为同位素年代学方法

具体包括:辉钼矿Re-Os法、黑钨矿和白钨矿Sm-Nd法、地质体定年法、含矿石英脉Rb-Sr法、含矿脉体中云母K-Ar法及Ar-Ar法等。此外

对上述方法的测试原理、样品选择原则、主要测试单位等进行系统详细的阐述。钨成矿年龄的确定

将有助于划分成矿期次、建立成矿序列、掌握成矿规律

是进一步探讨区域内成矿与成岩关系的重要前提。

Abstract

The metallogenetic chronology of tungsten is one of the most significant research topics of such tungsten deposits.The detection methods for the metallogenic age are divided into direct dating and indirect dating.There are a series of isotopic geochronolog methods in dating

which include Re-Os dating of molybdenites

Sm-Nd dating of wolframite and scheelite

geological body dating methods

Rb-Sr dating of ore-bearing quartz veins

K-Ar or Ar-Ar dating of mica in the ore-bearing veins

etc.In addition

the testing principle

samples selection principle and main test authorities of above methods were described detailedly.The determination of tungsten mineralization age could help to identify metallizing phase

built metallogenic sequence and summarize metallogenic regularity.The age is also the significant premise for discussing the relationship between diagenesis and mineralization in research area.
