Abstract: Abstract The Tiemurt Pb-Zn-Cu deposit (metal reserve: 0.29 Mt (Pb + Zn) and 0.14 Mt Cu) is hosted in the Kangbutiebao Formation volcanic-sedimentary rocks in the Chinese Altay Orogen, NW China. Although some geological and geochemical characteristics of… read more here.

Abstract: Abstract High‑uranium (~4200 to 8500 ppm U) columbite-group minerals (CGMs) from No. 1 pegmatite at Dakalasu, the Chinese Altay orogen were used to assess the effect of metamictization on the U Pb isotopic systematics. Backscattered electron (BSE)… read more here.
