Abstract

Adakites have an indicative significance to deep-seated structures of orogenic belt and thermal regime, and a closely relationship with the minralization of Cu and Au. The metallogenic mother rock of Sangbujiala skarn copper deposit, in Zetang, southern margin of the East Gangdise metallogenic belt is Late Cretaceous granodiorite. The major elements are characterized by higher SiO₂ (>56%), Al₂O₃ (>15%), Na₂O (≥ 3.5%) and K₂O (>2%), lower MgO ( < 3%). Na₂O/K₂O is 1.03~1.43, with an average of 1.22. The analyzing results of race earth and trace elements show higher Sr (>400×10^-6), lower Yb ( < 1.9×10^-6) and Y ( < 15×10^-6), higher Sr/Y (86.88~132.22, >20) and La/Yb (>10), enriched in LREE and depleted in HREE, and no negative anomalies of Eu, similar to those of adakite. By geochemical and geological characteristics, it was may be formed in partial melting of subduction oceanic plate of the O-type adakites, which interacted with mantle peridotite, showing that the southern margin of Gangdise has O-type adakites mineralization.
- Gangdise metallogenic belt,
- skarn copper deposit,
- adakite,
- Late Cretaceous
