80～81年我组与地质配合，在一个约65平方公里的岩体上进行基础地质研究和成矿预测，物探的任务是通过对区域物探资料的研究，提供岩体的空间形态。利用的资料主要有1∶2.5万航磁、1∶1万地磁、1∶5万重力及部分1∶10万电测深资料。其中磁法效果较好，而重力由于岩体与围岩仅有约-0.03克/厘米~3的密度差，在岩体上虽然显示了重力低，但异常形态却
From 1980 to 1981, our group cooperated with geology to carry out basic geological research and metallogenic prediction on a rock mass of about 65 square kilometers. The mission of geophysical prospecting is to provide the space shape of rock mass through the research on geophysical data of the area. The main data used are 1: 25000 aeromagnetic, 1: 10000 geomagnetic, 1: 50000 gravity and 1: 100000 electric sounding data. Among them, the magnetic effect is better, and the gravity is only about -0.03 g / cm ~ 3 due to the difference in density between the rock mass and the surrounding rock. Although the gravity is low on the rock mass, the abnormal morphology
