GA lesions were separated by hammer and stainless-steel chisel from surrounding unaffected tissue before a scalpel was used to collect skeletal powders for elemental analysis by scraping to the full tissue depth into the skeleton from the apical area of the lesion or unaffected fragment. The skeleto...
Oolitic pyrite (Py-O), which has two sub-generations, occurs in the upper part of the oolitic bauxite. Typically, Py-O2 has a core and rim structure, where the core may contain altered primary Py-O1. While Py-M appears as occurs in the form of interstitial material in the lower part...
