Abstract

The Tebai gold deposit is located in the Yabulai - Bayinuoer archaeozoic continental arc fold belt in the east of Alashan platform uprise. The ore bodies occur in the Carboniferous slate and phyllite of the Mesoproterozoic Agulucou Formation, surrounding by the Hercynian Guancaitaolugai granite porphyry. This gold deposit belongs to the black rock series gold deposit. The ore-forming fluid has the characteristics of low temperature (150 - 250 ), low salinity (1% - 6%), low density (0.7g/cm3- 0.9g/cm3). The hydrogen and oxygen isotopes and trace elements features of the ore-forming fluid accoed with the characteristics of the magmatic hydrothermal mixing meteoric water. Concerning the geology characteristics, it is confirmed that this fluid sourced from the Guancaitaolugai granite porphyry. This granite porphyry is a post-collisional A-type granite, which may be formed by the post-collisional extension of the Zongnaishan-Shalazha volcanic arc and the Alxa Block. The metallogenic process and fluid feature of the Tebai gold deposit are similar with the other black rock series gold deposits along western part of the northern margin at the North China Craton, which reflect the unique characteristics of the black rock series gold deposits in this area.
