Coal Geology & Exploration
Fujian, located in the orogen region of the coastal areas of southeast China, exhibits well-developed structures and complex surface conditions, which make deep seismic reflection surveys challenging. In response to the diversity and complexity of seismogeological conditions in Fujian, this study optimized the seismic excitation means based on previous deep seismic surveys. Specifically, the combination of large, medium, and small guns was transitioned into the layout of normal guns (spacing of shot points: 600 m) and large shots (spacing of shot points: 15 km), leading to enhanced folds of large shots. Through simulation analysis, this study calculated the spacing of …

Coal Geology & Exploration
As an effective method to accurately reveal the deep geological structures and tectonic features of the Earth, deep seismic reflection profiling has been increasingly applied to the exploration of the continental and oceanic crusts, as well as the upper mantle of the lithosphere, making it internationally recognized pioneer technique for deep Earth exploration. This study examined the deep seismic reflection profile spanning across the Xiong’an New Area in Hebei Province, aiming to reveal the crustal structure and tectonic features of the study area. Key findings are as follows: (1) The crust in the study area can be divided into the …

Coal Geology & Exploration
Deep seismic reflection profiling has been internationally proven to be a leading technology for deep earth exploration. With longer arrangement and greater energy than those used in oil seismic exploration, this technology can detect the fine-scaled structures and tectonic features from the earth surface to the upper mantle. Therefore, it is widely applied to the detection of continental and marine crust and upper mantle, with fruitful achievements having been made in revealing deep earth dynamic processes, expounding on the geotectonic evolution, determining the basin-mountain coupling, inferring the metallogenic and reservoir formation conditions, and analyzing earthquake disasters. This paper systematically reviews …
