The lithospheric structure and deep processes of the Mesozoic mineral systems in east China: constrained from integrated geophysical data

Summary Financed by the SinoProbe, a national collaborative multidisciplinary Earth science research project in China, the authors has conducted multi-scale and integrated geophysical exploration across the middle and lower reaches of Yangtze Metallogenic Belt (YMB) in east China. The data range in scale from terrane, district to camp or mine. The methods included broad band seismic, reflection seismic profiling, magnetotelluric sounding and gravity and magnetic modelling. The results provide first-order insights into the physical and structural properties of the lithosphere and upper mantle beneath the YMB, and thus provide in depth understanding of the deep processes that control the initiation and evolution of intra-continental mineral system.
