Western Tianshan, Xinjiang, is endowed with good exploration prospecting for porphyry-type copper deposit but also faces great challenges. Some sulfide mineralized rock enclaves (monzonite porphyry and fine-crystalline diorite) were recently discovered in the andesite in the Tawuerbieke gold district, Tulasu Basin.  Based on copper mineralization, acid hydrothermal alterations, the high-sulfidation and the low-sulfidation epithermal gold deposits in the basin, it is believed that the porphyry-epithermal Cu-Au metallogenic system might occur in the Tulasu basin, western Tianshan, and the Tawuerbieke may be an important target for porphyry Cu-Au exploration.
