<p>Electron Backscattered Diffraction (EBSD) is widely used to analyze rock petrofabrics, providing critical insights into deformation history and regional geodynamics. However, discrepancies often arise when comparing EBSD-derived petrofabric interpretations with those obtained through petrology, geochemistry, or even among different researchers studying the same region. These inconsistencies highlight concerns regarding the reliability of EBSD petrofabric data. While numerous studies employ EBSD to investigate mineral fabrics, researchers often overlook variations in geological conditions, data acquisition, processing, and representation, as well as their collective impact on data reliability. The lack of systematic and quantitative assessments of these factors undermines the robustness of geological interpretations based on EBSD. This study systematically evaluates factors influencing the reliability of EBSD petrofabric data, categorizing them into instrumental and geological factors. A systematic approach is applied to assess the correlation between individual factors, minimizing their mutual interference and isolating their respective effects on data reliability. Key factors such as sample preparation, calibration methods, step size, data cleaning, and projection techniques are quantitatively analyzed alongside geological parameters, including mineral species, rock composition, deformation conditions, water content, and melt presence. The results reveal strong correlations between influencing factors, with geological conditions exerting a more substantial impact on petrofabric reliability than previously recognized. Contrary to conventional assumptions, instrumental factors primarily act as amplifiers of geological influences rather than independent determinants of data reliability. This deeper understanding of contributing factors suggests that refining sample selection strategies in EBSD studies can lead to more accurate geological interpretations. By providing a systematic and quantitative evaluation of the factors affecting EBSD petrofabric reliability, this study enhances the methodological framework for EBSD-based geodynamic research. These findings underscore the need for a more comprehensive approach to data interpretation, ultimately improving the reliability and applicability of petrofabric analyses in structural geology and tectonic studies.</p>
