英文摘要	Adularia sample was collected from epithermal Au-, Ag-bearing quartz-adularia veins from Hishikari, Japan. This adularia is rich in K, Or=94.63, clear, transparent, fine-grained and closely associated with quartz. In this study, it was determined by XRD, IR and Si-29, Al-27 MAS NMR methods. The adularia studied is of high sanidine with triclinic domains in it. The occupancy of Al 2t(1)=0.60, IR ordering theta=0.15. Si-29 NMR spectrum of this adularia shows a broad triplet peak, i.e, 3 poorly separated peaks at -94.9, -96.7, -99.9. This kind Si-29 NMR spectrum for natural high sanidine has never been reported before. And the Al-27 NMR spectrum gives an asymmetry peak with chemical shift at 58.7 extending slightly to the low frequency. Under a violent boiling environment, Hishikari adularia rapidly crystallized from a supersaturated solution.
