INITIAL REPORT ON THE MIDDLE-LOWER YANGTZE METALLOGENIC BELT SEISMIC EXPERIMENT

From May 2012 to June 2014, China University of Geosciences (Beijing) deployed a temporary broadband seismic network that was designed to explore the crustal and upper mantle structure of the Middle-Lower Yangtze Metallogenic Belt (MLYMB) and its adjacent regions with an average station spacing of ~50 km. The first phase of this experiment consists of 20 CMG-3ESPC broadband seismometers. Given the importance of data collected in this experiment to, and the timely nature of, the study of the deep geodynamic process and magmatic activity mechanism of the MLYMB, this initial report presents the experiment setting, initial data collected, and results of preliminary data analysis in the spirit of promoting data exchange and collaborative study of the MLYMB. This project is supported by the Ministry of Land and Resources of China
under the Project SinoProbe-03, the National Science Foundation of China 41374057, and the Program for New Century Excellent Talents in University (NCET).
