This video provides crucial data validation and robust QA/QC procedures for processing historical geochemical data, tackling issues like varying detection limits, effectively handling below detection limits, and highlighting the critical role of metadata importance for accurate data interpretation and data normalization. We'll delve into effective analytical methods, the significance of certified reference materials for ensuring precision and accuracy, and best practices for sample collection to minimize contamination control. Learn about comprehensive data processing techniques, including how to perform a thorough laboratory audit based on standard operating procedures and adherence to standards like ISO 17025, and how to utilize control charts for continuous laboratory QC. We will demonstrate strategies for integrating disparate datasets using regression analysis and emphasize responsible data management to make your valuable geochemical information FAIR (Findable, Accessible, Interoperable, Reusable) for diverse applications, including geochemical exploration and environmental geochemistry. This guide is essential for all geologists and earth science professionals seeking to optimize the reliability and utility of their geochemical datasets for modern exploration and research.
