Geochemistry Features and the Tectonic Setting of Intrusive Rocks in Halegati, Xinjiang

Abstract:

Halegati Fe-Cu deposit of skarn was located in the Boluokenu metallogenic belt. With the research of the geochemistry characteristic of granodiorites, the results showed that the rocks belonged to I type granite with the features of siliceous, metaluminous, low magnesium , high-k and alkalic. The intrusive rocks had a close association with the mineralization, which had the features of enrichment of large-ion lithophile elements (K, Rb, Ba, Th) and relative depleted in high-field strength elements (Nb, Ta, P, Ti).The intrusive rocks in Halegati had the characteristic of strongly differentiation between LREE and HREE and negative Eu anomalies obviously. The REE distribution curves had the right types. The intrusive rocks were formed in the environment of volcanic arc, which produced in the tectonic setting of supra subduction zone.
