摘要 湖南雪峰隆起东南部的隐伏岩浆岩体在卫片上的环形影象,与重磁异常有很好的一致性;隐伏或半隐伏的含煤盆地在卫片上也是环形影象,呈重力低反映。这对利用卫片、重、磁综合解译、推断岩浆岩体和含煤构造具有指导意义和实际价值。 The concealed magmatic rock bodies at the southeast of the Xuefeng Upheaval in Hunan are circular in the landsat images. These circular images are identical wonderfully with those in the gravity and magnetic anomalies figure in shape, size and location. The concealed or subconcealed coal basins are also of circular shapes in the landsat images, but show the negative anomalies in the gravity figure. So it is of practical value to make use of the landsat images and the materials of the gravity and magnetic anomalies for explaining and distinguishing the magmatic rock bodies and the coal basins.
