Micro and nanoscale textural and compositional zonation ...
Textural and compositional microscale (10100 mu m) and nanoscale (10100 nm) zoning in a plagioclase phenocryst from a fresh, synmineralization diorite porphyry (Black Mountain porphyry CuAu deposit, Philippines) was characterized for major and trace elements using electron microprobe, laser ablationinductively coupled plasmamass spectrometry, and atom .
