随着分析技术的飞速发展，从而使地质学研究逐渐由定性描述向数据定量评价转化。但多数地质分析测试技术对某些含量很低或比较特殊的样品分析时仍存在不足或不能满足研究目的；然而，激光剥蚀电感耦合等离子体质谱（ LA-ICP-MS）微区分析技术可以实时、快速、高灵敏度、高分辨率及多元素同时测定，并可提供同位素比值信息而使上述问题得以解决。近年来，LA-ICP-MS分析技术在金矿中的应用，对准确厘定金矿床的成矿时代，探讨成矿物质来源、了解矿床的成矿机制及正确认识矿床的成因等方面具有重要意义。
With rapid development of the analysis technology ,the geologic study gradually converts from qualita-tive description to quantitative evaluation of data .But most of the geological analysis and testing technology for some low content or special samples still have been insufficient or cannot meet the research purpose ;However ,Laser abla-tion-Inductively Coupled Plasma -Mass Spectrometer ( LA-ICP-MS) microanalysis technology can be real-time,rapid, it has high sensitivity ,high resolution and is able to test the multiple elements at the same time ,also it can provide iso-tope ratio information so as to solve the above problems .In recent years ,the LA-ICP-MS analysis technology has been applied in gold deposits ,which has great significance in calculating the metallogenic age of gold deposits accurately , discussing the ore-forming material sources , understanding the metallogenic mechanism of deposits and knowing the genesis of mineral deposit correctly ,etc.
