Abstract: The linglong goldmine is mainly controlled by the NEE and NE treading faults, whose forming and motion features are closely related to the activity of Tanlu Fault.The main ore bodies are concentrated on the combination parts of two groups of faults.In the early Mesozoic,this area was affected by the Tanlu Fault.The NNE treading Ling long Fault is a sinistral strike-skip moving fault.while the character of the NE treading Podouqing Fault is mainly squeezable and sinistral movements.In the late Early Cretaceous,the NNE treading faults was moving dextrally,while the NE treading fault was on sinistral movement.All these suggest the multi-periodicity and complexity in the motion of faults.The characters of tectonic rocks imply that the ore-control fractures have suffered two stages of transformation- the ductile stage an d the brittle stage.Ore bodies are mainly occurred in lower plates .The scale of ore body an d ore-control fracture are positively correlated .
