Southwest of Fujian is one of main ore districts of China, thrust controlling mineral deposits model over there means that there may be deep concealed deposits in the overlapping areas of the thrust, and refection seismic which has great depth penetration and higher resolution has great potential to delineate these complex structure and give some clues to mineralization. In 2015, an experimental 13.8 km 2D reflection seismic survey named Fujian 2D was conducted in this region. For the data acquisition, the designed shot and receiver intervals were 60 m and 20 m, respectively, and all 691 receivers recorded seismic signals for each shot. Due to the properties of the tested environment, some shot points were re-designed but the average fold reached 64 in the middle at more than 10 km distance. During the data processing procedure, conventional technologies involving statics, noise elimination, deconvolution, and iterative velocity analyses were applied. After the pre-stack time migration failed to obtain a ...
