Abstract:

Chadong silver-gold field occurs at the intersection of the northernmost of Wuchuang-Sihui NE trending main fault zone and the Guizi-Tashi WE trending arcuate fault zone，of which the fault and the secondary fault controls the gold distribution.Chadong silver-gold field is the very profitable tectonic metallogentic field with the advantageous conditions whose structural is relatively well developed.The survey resumed the relationship between the geologic features，remote sensing geological interpretation and the mineral vein which mainly combined the geological exploration results of Chadong silver gold field.Resulted from the analysis of the ore-controlling factors and the summary of the metallogenic regularity and the main ore-controlling factors，the result had been gotten that: There is a close relationship between the faulted structure and the vein.The faulted structure is the main factor of which controls the size of ore bodies，the occurrence and the morphology.Besides it also creates a good space for the activity of the ore solution and filling.And the 36 vein is possibly to extending to the southwest，which is worth recourse strengthening of the surface to the south.Investigation of the NE-NNE veins should been strengthened to finding new veins as the close relationship between the faulted structure and the vein.This area is expected to find large silver gold polymetallic deposit.By analyzing the ore potential，puts forward suggestions on the nest step prospecting direction.
