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
|
摘要
为落实安徽庐枞地区北部的龙桥铁矿含矿层位在第二找矿深度的空间分布,本文应用小道距、长排列接收的地震反射初至波走时数据,运用层析成像方法,得到该地区近地表1000m以上的速度结构。研究结果显示,反射地震初至波携带了丰富的上地壳速度结构特征和界面变化的构造信息,精细的速度结构揭露出龙桥铁矿隐伏岩体顶界面深度与起伏形态,发现岩体顶面凸起及陡变化部位与矿体分布存在着明显的对应关系。长排列的深地震反射初至波走时层析成像方法能够为金属矿集区深部隐伏矿床的勘探与研究提供岩体的空间分布信息。
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.
