Abstract:

We research geological setting and ore-controlling factors of Co polymetallic ore in Kendekeke mine area by using the technology of geology and geophysical-geochemical,and the methods of trenching,drilling,geologygeophysical-geochemical profiling measurement.The results of the research show that Kendekeke area is a typical composite deposit,the elements of iron, gold, cobalt, bismuth, lead, zinc, molybdenum and copper can be constitute orebody independent.Ore-forming elements not only can symbiosis,but also they can be associated,they are close contact in the space.The main orebody is calcareous clay chert,it shows strip and worm shape,and it has obviously thermoplastic deformation,the genesis can be attributed to hot water deposition-reworking type deposit.

Key words: Co polymetallic ore, Geological characteristics, Ore genesis, Prospecting criteria, Kendekeke mine, Qinghai Province
