内容記述 | By using the total intensity data of two aeromagnetic survey flights by the 21st Japanese Antarctic Research Expedition, geomagnetic anomalies over the moraine field to the north of Mizuho Station are obtained. The reduced geomagnetic anomaly profile for each survey flight has a relative uncertainty of 20-30nT, and the hand contouring is made at intervals of 100nT. The obtained geomagnetic anomalies have a short wave-length (10-30km) variation from -200nT to 200-300nT with the associated anomaly eyes of 400-500nT amplitude. The free-air gravity anomalies in Mizuho Plateau suggest the existence of a subglacial mound of about 2400m bedrock height, and the aeromagnetically surveyed area is situated at the periphery of such subglacial mound. The obtained short wave-length geomagnetic anomalies may be related to the steep change of bedrock geology beneath the 2000m thick ice sheet. | |||||
