Tools for Parsing and Analysing Itrax Core Scanner Data.
The Itrax Core Scanner (Cox Analytical Systems, Sweden) is a multi-sensor device for analysing geological and sediment cores. It produces high-resolution line-scan photography, line scan x-radiographs, and energy-dispersive x-ray florescence elemental composition analysis. The scanner is non-destructive, automated and capable of high resolution (~0.2 mm) down-core resolution.
The datasets produced by the scanner can be large and complex. This software, written for the R environment, will assist users in parsing the data, including tasks like integrating multiple, possibly overlapping core sections, repeat scans of core sections and assigning depth information to the scan data.
It has functions to assist with plotting image and compositional data, as well as visualising raw scan data. It also has functions for performing various common multivariate analyses on the compositional data, like PCA and clustering.
