Abstract
The characteristics, distribution and the origin mechanism of geothermal anomaly in the North China Basin were discussed in this study. It is proposed that the uplifting of the giant sub-mantle plume is the dominant power for the crust breaking, faulted depression as well as the origin and evolution of geothermal fields in the North China. And the geothermal gradient distribution resulted from secondary uplifts and depressions within the North China faulted depression shows the representation of structure controlled geothermal anomaly.
