This region has a basin and range topography with Neoproterozoic and Palaeozoic units exposed at NW{\textendash}SE trending ranges rising along major intracontinental faults and with intermontane basins filled by Mesozoic and Cenozoic sediments in between. The map shows clear N{\textendash}S tectonic zonation featuring the northerly Precambrian Baidrag microcontinent, the lower Palaeozoic Lake Zone in the centre and the southerly Palaeozoic Gobi-Altai and Trans-Altai zones. Gravity highs are located in the SW part of the map and low to intermediate Bouguer anomalies in the NE part. NW{\textendash}SE trends of gravity anomalies correlate well with the contact between the Trans-Altai and the Gobi-Altai zones but the important first-order geological boundary between the Lake and Gobi-Altai zones cannot be delineated by the gravity gradients.}, year = {2020}, url = {https://www.tandfonline.com/doi/full/10.1080/17445647.2019.1700835}, doi = {https://doi.org/10.1080/17445647.2019.1700835}, }
