摘要
Deep seismic reflection profiles discovered the fine crustal structure of Luzong deposit area,and we obtained new discovery on studying the deep structure of Luzong volcanic basin and tracing deep process of the mineralization.From Yangtze River to Dabie Mountain,Moho goes deeper from about 30 km to 33 km with 3 km offset beneath the Luohe deposit.Luzong volcanic basin is an "ear-like" asymmetric basin of eastward development along the Luohe fault,there is no other half basin buried under the red layer.Luohe ore is corresponding to the offset of Moho and the transition belt of structure.The weak reflection zone in the lower crust of the Luohe may be the surging and eruption channel of magma and mantle fluid.Tanlu fault,Luohe-quekou fault and Changjiang fault are three important faults in the Luzong area.Tanlu behaves a dissymmetrical flower structure,and cut through crust nearly vertically.Xiaoling and Longqiao ores probably located in two flanks of volcanic rock uplift.
