A novel 3D sampling method of geological rock-core using X-ray fluorescence

TL;DR

This paper introduces a new 3D X-ray fluorescence scanning technique for geological rock-cores that enables detailed elemental mapping, reducing sample preparation time and costs while providing richer surface composition data.

Contribution

It presents a novel 3D XRF method for geological samples, allowing comprehensive elemental analysis and mapping of rock-cores in a more efficient manner.

Findings

Successful reconstruction of 1D, 2D, and 3D elemental maps

Reduction in sample preparation time and costs

Enhanced surface elemental distribution information

Abstract

The current work describes a proof of concept of a 3D XRF scanner, which is able to perform elemental analysis over the cylindrical surface of geological rock-core and to reconstruct a 1D, 2D and a 3D elemental map of the scanned area. The presented method will reduce the time and cost for sample preparation, but also will reveal more information about the distribution of the elements over the surface.
