地震法用于大规模金属矿产勘探并不常见。然而,加拿大地质调查所(CGS)的地面物探处最近推出了一项“最佳公共补偿”(optimum common offset)浅层地震反射绘图技术。这是一种将石油地震勘探技术适当改进后应用于金属矿产勘探行之有效的方法。在适宜的工作环境中,无论地下情况如何复杂,运用该项技术即可精确地绘出覆盖层与基岩的接触面以及覆盖层剖面图。 据加拿大地质调查所Jim Hunter和Susan Pullan报道,一种独特的,应用该技术勘探金矿的先进方法已在安大略省北部地区广泛应用。该地区由厚度不等的粘土和泥 Seismic method for large-scale exploration of metal minerals is not common. However, the Geophysical Prospecting Unit at the Geological Survey of Canada (CGS) recently introduced a shallow seismic reflection mapping technique called “optimum common offset”. This is an effective method for the exploration of metal minerals after the oil seismic exploration technology has been properly improved. In the right working environment, no matter how complex the underground situation is, the technology accurately maps the interface of the overburden with the bedrock and the profile of the overburden. According to Canadian Geological Survey Jim Hunter and Susan Pullan, a unique and advanced method of using this technology for gold exploration has been widely used in the northern part of Ontario. The area consists of clay and mud of varying thickness
