Integrating rotational components to optical properties observed in petrographic thin sections via automated image acquisition and analysis
The analysis of petrographic thin sections is a widely used process for the identification of the mineralogy of rocks and the analysis of their textural and microstructural characteristics. Despite the benefits of petrographic thin section analysis, it remains a time-consuming process with the …
