Abstract:

Yelonggou gold mine is located in the east of Kunlun metallogenic belt.It occurs in the early Proterozoic Baishahe rock group and Variscan granodiorite area.Through 1∶5 million stream sediment survey,we preliminary identify the distribution and assemblages of elements,unusual intensity and concentration zone characteristics in the area.Furthermore,we circle a higher peak gold anomaly in the area.Through 1∶2.5 million stream sediment,we find two alteration fractured zone which containing gold,and gold grade is 2.8～7.28 g/t.We analyze the ore body shape, occurrence,structure and spatial distribution of mineralization and geological structures,stratigraphy and magmatic relations and other aspects of ore bodies and abnormal distribution,study the formation of deposit,fracture tectonic system and distribution of magmatic rocks.On this basis,we analysis of the relationship between polymetallic ore mineralization spatial distribution and tectonics,formation,magmatic rocks.Finally,we establish the indicator for prospecting and to learn the role of the direction.

Key words: Geological characteristic, Geochemistry characteristic, Prospecting indicator, Yelonggou gold mine, Qinghai Province
