| 摘 要： | 广西区域岩石物性调查,给出了区域岩石的密度、磁性、电性特征及其时空分布规律,划分了密度界面,明确了磁性基底的客观存在,构思了岩石层序地球物理模型,提出了不同时代花岗岩的磁性变化特征,建立了隐伏在岗岩的重力低预测模式.在区域构造填图、隐伏花岗岩填图、小盆地油气田构造研究、固定矿产成矿带预测以及某些基础地质研究等方面,具有重要意义. |

| Abstract: | Through regional investigation of physical properties of rocks in Guangxi, the authors have determined the density, magnetism, electric characteristics and temporal-spatial distribution of regional rocks, disclosed the boundary separating different densities, made clear the existence of magnetic basement, worked out a geophysical model for stratigraphic sequence of rocks, indicated magnetic variation characteristics of granites of different ages, and established a pregnostic model for gravity low of concealed granites. These achievements will be surely of great significance in such aspects as regional structural mapping, concealed granite mapping, study of oil-gas structures in small basins, prognosis of solid ore minerogenic belts and basic geological research. |
