Reflection seismic first-arrival wave tomography of Longqiao iron deposit and concealed deposit forecast in Luzong iron-polymetallic ore concentrated area.
庐枞铁多金属矿集区龙桥铁矿反射地震初至波层析成像与隐伏矿床预测

For the implementation of Longqiao iron-containing ore bed in the depth of the spatial distribution of the second exploration to the northern part of Luzong area, Anhui Province, this paper makes the use of the small trace space with long-offset geophones to receive the seismic reflection travel-time data, using tomography methods, getting the region over the near-surface velocity structure of 1000m. The results show that seismic waves carry a wealth of upper crustal velocity structure features and interface changes in the structure of information, fine velocity structure of exposed Longqiao iron buried depth and relief of the top interface, and found that there is a clear correlation between the top surface of raised rock and steep changes in the distribution of parts with the ore body. Long-offset deep seismic reflection travel-time tomography method can provide information on the spatial distribution of rock mass for the exploration and research of deep concealed ore deposits in metal concentration area.
