摘要
The inhomogeneity of relationship between lithospheric thinning and mineralization were put forward and discussed.The basic mechanism for mineralization of gold,molybdenum and tungsten in large in the eastern China was that gold,molybdenum and tungsten deposits,which were inhomogeneous in lithosphere because of lithospheric thinning,were depleted and taken into earth crust.The time ranges for mineralization of gold,molybdenum and tungsten in large caused by lithospheric thinning in North China Craton,began from tectonic transition and ended in period of magma transforming from enriched mantle source to depleted mantle source,could be from 163~136 Ma to 117~80 Ma.The important reason for the difference of time-space distribution of gold,molybdenum and tungsten deposits and ore concentration areas could be the inhomogeneous lithospheric thinning in time and space.
