Preliminary 3-D Electrical Resistivity Model of the Ulaanbaatar Region Using Magnetotelluric Array Measurement

The capital of Mongolia is Ulaanbaatar (UB), which is situated in the central region of the country. Over the past few decades, the city has expanded and developed, establishing itself as the most extensively developed metropolis in Mongolia regarding infrastructure and commerce. While this impact has resulted in development for the nation, it has also led to environmental and social concerns, including traffic congestion and air pollution. The resolution of these issues necessitates a more comprehensive understanding of the geological formation of the region, which can be achieved through the sustainable development of renewable energy and road construction. UB is situated at the confluence of the Tuul River and is enveloped by mountains significantly higher than the surrounding terrain. One is the Bogd Uul intrusive/plutonic granite, situated south of Ulaanbaatar. It spans a 200 km2 area and is believed to have been formed during the Late Triassic (Khishigsuren et al., 2006, 2009) to the early Jurassic period, with an age of 208 Ma. One of the strategies to mitigate the challenges previously identified is to drill Bogd Uul for the purpose of constructing the road.
