Micro PIXE analyses of Furnace and Converter Mattes for the determination of trace element distribution and concentrations
… (PIXE) were performed to investigate the distribution and concentration of trace elements. These levels of sensitivity are beyond that of the electron microprobe. The objective of these analyses was to examine low level concentrations (ppm or ppb) in phases such as alloys, oxides and …

Kinetic processes of mantle minerals
… spinel coexist in peridotite compositions. The trace element distribution among the product phases (opx and cpx) subsequent to the garnet breakdown reaction is in disequilibrium, due to the differences of diffusivity between major and trace elements. The presence of disequilibrium distribution …

Influence of Solution Composition and Temperature on the Strontium Content of Amorphous Calcium Carbonate and Subsequent Calcite
… and vital effects are known to affect the trace element composition of the CaCO₃ biomineral products. The recent discovery that calcifying organisms produce amorphous calcium carbonate (ACC) as an intermediate phase during the crystallization process calls into question whether this pathway …

Constraining Metamorphic and Tectonic Evolution in Convergent Terranes: How Trace Elements and Mineral Inclusions Shape Mechanical and Reconstructive Models
… to a low-density polymorph may occur. Trace element uptake, particularly Ti, have been characterized in quartz and understood to be the result of a temperature- (and to a lesser extent, pressure-) sensitive substitution for Si4+. However, the application of the Ti-in-quartz …
