Here, we use airborne gravity and aeromagnetic anomalies for characteristic analysis and inverse calculations. The gravity and magnetic images show three distinct geophysical domains. Based on the gravity anomalies, a dense lower crustal root is modelled to underlie the GSMs, which may have formed by underplating during the continental collision of Antarctica and India. The high frequency linear magnetic characteristics parallel to the suture zone suggest that the upper crustal architecture is dominated by thrusts, consisting of a large transpressional fault system with a trailing contractional imbricate fan. A 2D model along the seismic profile is created to investigate the crustal architecture of the GSMs with the aid of depth to magnetic source estimates. Combined with the calculated crustal geometry and physical properties and the geological background of East Antarctica, a new evolutionary model is proposed, suggesting that the GSMs are underlain by part of a Pan-African age advancing accretionary orogen superimposed on Precambrian basement.<\/jats:p>","DOI":"10.3390\/rs15020306","type":"journal-article","created":{"date-parts":[[2023,1,5]],"date-time":"2023-01-05T02:00:57Z","timestamp":1672884057000},"page":"306","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Tectonic Implications for the Gamburtsev Subglacial Mountains, East Antarctica, from Airborne Gravity and Magnetic Data"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0053-4777","authenticated-orcid":false,"given":"Guochao","family":"Wu","sequence":"first","affiliation":[{"name":"Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"},{"name":"Key Laboratory of Submarine Geosciences, Ministry of Natural Resources, Hangzhou 310012, China"}]},{"given":"Fausto","family":"Ferraccioli","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Oceanografia e di Geofisica Sperimentale, 34010 Sgonico, Italy"},{"name":"British Antarctic Survey, Cambridge CB3 OET, UK"}]},{"given":"Wenna","family":"Zhou","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mineral Resources in Western China (Gansu Province), School of Earth Sciences, Lanzhou University, Lanzhou 730000, China"}]},{"given":"Yuan","family":"Yuan","sequence":"additional","affiliation":[{"name":"School of Geospatial Engineering and Science, Sun Yat-sen University, Zhuhai 519082, China"}]},{"given":"Jinyao","family":"Gao","sequence":"additional","affiliation":[{"name":"Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"},{"name":"Key Laboratory of Submarine Geosciences, Ministry of Natural Resources, Hangzhou 310012, China"}]},{"given":"Gang","family":"Tian","sequence":"additional","affiliation":[{"name":"School of Earth Sciences, Zhejiang University, Hangzhou 310027, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"195","DOI":"10.1016\/S0012-821X(01)00587-8","article-title":"Pan-African intraplate deformation in the northern Prince Charles Mountains, east Antarctica","volume":"195","author":"Boger","year":"2002","journal-title":"Earth Planet.
