Abstract

In-situ micro-area compositional analysis of minerals is a core technical approach in geological science, materials science, mineral resource exploration and other fields. Its core value is to realize accurate, non-destructive and in-situ detection of chemical compositions of minerals at the micro-scale, providing critical data support for the interpretation of ore deposit genesis, research on mineral formation mechanisms, and exploration of strategic mineral resources. Aiming at the shortcomings of traditional in-situ micro-area compositional analysis techniques for minerals, such as low spatial resolution, significant matrix effect, low analytical efficiency, and insufficient detection accuracy of trace elements, this paper systematically discusses the innovation directions and implementation paths of in-situ micro-area compositional analysis techniques for minerals by integrating research advances in instrument upgrading, analytical method optimization and data processing technology innovation in recent years.
