| 摘 要： | 硅化木具有极高的收藏价值和科研价值，但浅埋硅化木的探测仍无较好手段。在即墨马山地区首次使用物探手段进行浅埋硅化木的探测研究。在前期高密度电法探测的基础上，对电阻率异常点进行地质雷达复测，结合区域地质背景和硅化木的产出特征，硅化木异常多表现为小的抛物线突起，且异常深度集中在2～6m，最后对异常点进行钻孔验证，结果表明地质雷达可有效探测浅埋硅化木。

| Abstract: | The shallow buried silicified woods have a high collectible and scientific value , but there is no effective way to detect them . The geophysical exploration method is firstly used in the Ma Mountain of Jimo City for the investigation of shallow buried silic-ified woods .On the basis of previous surveys with high density electrical method ,the abnormal points of electrical resistivity are re-detected by using Geo-radar .Considering the regional geological background and the characteristics of silicified wood occurrence , the abnormalities generated by buried silicified woods appear often as small parabola-shaped convexes and mostly concentrate in a 2~6 m depth .These abnormal points are finally tested through drilling holes and the results indicate that Geo-radar can effective-ly detect the shallow buried silicified woods . |
