Short summary
Choosing samples from large sections of hard-rock cores often relies on preliminary chemical analyses, which can be limited and therefore misrepresentative of full chemical variability. This study adapts X-ray fluorescence core-scanning techniques for use on hard-rock basalt cores to outline a method that provides accurate chemical information in greater detail relative to traditional analytical methods. The presented workflow suggests significant contributions to new and legacy core research.
