This preliminary study of the geochemical features in Puchiya area, Xaitongmoin, Tibet, was based on the 1∶50 000

stream sediment survey. It included element distribution characteristics, element anomalies, element correlation and element

anomaly assemblage. The result shows that the study area might be a prospective area for Pb, Zn and Cu. It is inferred that ore

deposits in Puchiya area are probably volcanic type lead-zinc polymetallic deposits and acidic intrusive-associated porphyry

copper polymetallic ore deposits. The Zhanzanmubu area is expected to be a prospective area for volcanic type lead-zinc

polymetallic deposits and the Seyao area is likely to have copper polymetallic ore deposits associated with intermediate-acidic

intrusive rocks.
