The main idea was to see what was easily available on ironstones. From there what is their distribution telling us about possible parent bodies that presumably are not outcropping or absent.

The model given by DRE in the initial announcement suggests a blind carbonatitic intrusive with radiating and arcuate dykes/veins/sills.





With the release of the thorium data and DT confirming some 20% of the targets show evidence of ironstones worthy of follow up the model may need to be re-examined. Or, multiple parent bodies added? Or.

This PDF is a combination of literature research - much going over previously covered papers. Pirjano et al's Gifford Creek Complex paper has some photos that show what led HAS and others to look at the ironstones. Too technical for most but some useful images.

I did wonder if Bayan Obo in Inner Mongolia could offer some clues. Probably not but an interesting place to look at if all the sites (1-5) at the end are REE related. Maybe some hint of the overall scale that could emerge in the Gascoyne. Too large so put in PDF.
