【摘要】 对苏北地区主要岩石物性的调查结果发现 ,科学钻探的目标体榴辉岩有很大的密度 ,与其他围岩的密度差达 0 9× 1 0 3kg/m3,具有重力勘探的物性基础 ;除角闪石化榴辉岩的弹性波速与围岩相近外 ,榴辉岩的弹性波速高于其他围岩 ,地震勘探在该区应是一种有效的勘探方法 ;就磁性而言 ,榴辉岩的磁性介于围岩磁性之间 ,与围岩磁性没有明显区别 ,但金红石矿化榴辉岩的磁性有明显差别 ,因此磁法勘探在该区受到岩石组成复杂性的限制 .更多还原

【Abstract】 A petrophysic investigation is carried out in Maobei area, where Chinese scientific drill is located. In general, there is a prominent petrophysical difference between eclogite and its surrounding rock. Density of eclogite is higher 0.9(×10 3kg/m 3) than that of other rock, implying that gravitational exploration is most effective method used to find eclogite body as science drill target. P-wave velocity of eclogite is higher also, suggesting that seismic exploration is effective. Magnetic properties of eclogite are not largely different from wall rock, and effectiveness of magnetic exploration for locating eclogite body is limited by complex assemblage of eclogite and its surrounding rock.更多还原
