Compaction‐Driven Fluid Localization as an Explanation for Lower Crustal Electrical Conductors in an Intracontinental Setting

Compaction‐Driven Fluid Localization as an Explanation for Lower Crustal Electrical Conductors in an Intracontinental Setting

We present electrical resistivity models, derived from magnetotelluric data, of the crust beneath the Bulnay region, Mongolia. They reveal that the lower crust contains a pattern of discrete zones (width of ~25 km) of low resistivity (
