| Abstract: | Piemontite quartzite is from the ductile shear zone of the southern Kudi western Gaizi in the Aoyitag of Aketao County，Kezilesu kerkezi autonomous state of Xinjiang，China.It is a part of the ophiolite suite of nothern part of the Western Kunlun Mountains，or a part of the Aoyitag Kudi suture zone of the Western Kunlun Mountains，in the alternation of strata made up of piemontite quartze，marbles，calcareous siltites，silty mudrock.Its mineral composition is simple，and mainly made up of quartz，piemontite，a litter of calcite and so on.Oxides of primary importance of piemontite quartze are SiO2(3545～3664)，Al2O3(1958～2133)，Fe2O3/FeO(766～912)，Mn2O3/MnO(1102～1132)and CaO(2283～2414).It is a conditions of formation which lower temperature(4055)and high pressure.Formed the protolith of the piemontite quartzite is derived from highly oxidized ferromanganese oxide and impure siliceous pelagic sediments for the piemontite schist.Piemontite quartzite are considered low greenschist and high pressure metamorphic facies series，in the process of A pattern subduction of Tarim plate，since Eocene Oligocene. |
