Geology of the Gobi and Mongol Altai junction enhanced by gravity analysis: a key for understanding of the Mongolian Altaides

Figures & data

Figure 1. Geological position of Mongolia in the frame of CAOB, according to Nguyen et al. (2018), modified from Buriánek et al. (2017).

Figure 2. Position of map sheet L-47-V within geotectonic map of SW Mongolia (modified from Nguyen et al., 2018).

Figure 3. Lithostratigraphic scheme of the Trans-Altai, Gobi-Altai, and Lake zones. Metamorphism: H, M, L – high, medium, low; P, T – pressure, temperature.
