| New fault systems have formed throughout Mongolia to accommodate North-South shortening brought on by the collision of the Eurasia and Indian plates. This study uses field measurements and observations, geomorphic indices, and Landsat data to determine whether faults in north-central Mongolia have experienced recent tectonic activity. Two field areas were studied to evaluate recent fault activity and to create geologic maps; Field Area 1 is approximately 2,300 km2 and located near the small town of Hishig-Ondur, and Field Area 2 is approximately 10,800 k2 and is located south of Field Area 1, just south of the Tuul River. There are two faults in Field Area 1 and four faults in Field Area 2 that show evidence of recent tectonic activity based on geomorphic observations observed during field investigations and hypsometric curve analysis using Landsat data. |
