文摘
- •
A 3D resistivity model based on EarthScope magnetotelluric data is presented.
- •
The model of the mid-continent constrains Precambrian structure and evolution.
- •
The model shows geometry, extent, and segmentation of the Midcontinent rift system.
- •
The model reveals the distribution of Paleoproterozoic (Penokean) metasediments.
- •
Hydration of the lithospheric mantle occurred in response to melt metasomatism.
