The article discusses the use of magnetotellurics to image the architecture of mineral systems and pathways of ore-forming fluids in Mongolia, focusing on metallogenic zones rich in copper, gold, and rare earth elements. The method is effective in imaging subsurface electrical resistivity distribution and is sensitive to fluid composition, making it suitable for characterizing lithospheric architecture and fault zones. The results reveal low-resistivity anomalies beneath known mineral deposits, suggesting the presence of fossil fluid pathways and aiding in the interpretation of mineral systems and tectonic boundaries in the region.

The article discusses research which analyzed data from magnetotelluric (MT) measurements across southern Mongolia to investigate the whole-lithosphere structure of a mineral system and determine the pathways and source of ore-forming fluids. Topics covered include an exploration of the three dimensional (3-D) models of the electrical resistivity structure throughout the whole lithosphere, and the impact of the structure of the lithosphere and crust on the evolution of ore-forming fluids.
