| contents | The Ōrākei paleolake micro-facies has been studied via the application of a combination of light microscopy, aided by high-resolution µ-XRF data sets (using appropriate elements or elemental ratios), EMPA enabled spatial elemental mapping, and/or the results of the RADIUS application (Rapid Particle Analysis of digital images by ultra-high-resolution scanning). The results of this work are made available in this repository. Both the elemental mapping and RADIUS results serve to support the interpretation of the µ-XRF line data. Spatial elemental mapping was undertaken as a trial since this approach provides additional spatial data that helps to better characterize variation in elemental composition within laminations, unlike elemental µ-XRF line scanning. Furthermore, RADIUS is a technique developed at Johannes Gutenberg University in Mainz (Germany) and is a procedure that allows the detection of allochthonous sedimentation events such as flood layers, dust, and turbidites. |
