Thrust nappe structure and its ore-controlling effects in the North Wuyi area

The North Wuyi area is characterized by advantageous mineralizing geological conditions and widespread mineral resources, but the formation and conservation of ore deposits are mainly controlled by thrust nappe structure. Many problems seriously affect the results of geological survey and mineral exploration. These problems include: whether regional thrust nappe structure form before, during or after mineralization, how about its fine structure characteristics, whether it has rock- and ore-controlling effects, and whether destruction, if any, may cause orebodies to be enlarged or buried or absent. This paper proposes the following: carry out areal and tracing geological reconnaissance, ascertain the regional distribution of thrust nappe structure and attitudes and structural patterns of different units, use 40Ar-39Ar and Re-Os dating techniques to determine the ages of formation of the thrust nappe structure and orebodies, use quantification analysis and fine structural analysis to study the genetic relations between the thrust and ore deposits and predict the possible location of hidden orebodies, and then further provide reference for looking for hidden ore deposits and enlarging ore prospects in the North Wuyi area.
