DISCUSSION ON THE GEOLOGY AND GENESIS OF LIBA GOLD DEPOSIT IN LIXIAN, GANSU PROVINCE

Liba gold deposit in Lixian, Gansu Province, belonging to altered fracture zone type, is hosted in Devonian epi-metamorphic fine clastic rocks. The ore bodies are strictly controlled by faults. The ore-forming matters are derived mainly from deep strata. The ore-forming fluid is a mixture of meteoric water, metamorphic water and magmatic water. The Zhongchuan granite serves as the heating dynamics for metallization.
