MT Targets: Colorado Plateau Margins and two areas in Central and Eastern USA

• Edges of the Colorado Plateau – examine edge driven convection and the possible delamination process that initiates from the edge of the Plateau.

• Eastern part of the South Dakota Gravity Low (~-200 mGal) and the northern Gulf Coastal Plain, where both heat flow and crustal attenuation are high.

Crustal Attenuation (Lg Q0) vs. Heat Flow

Blackwell, D. D., and Richards, M. 2004.

Blue to green indicates low heat flow (25-59 mW/m2). Yellow to red indicates high heat flow (60-150+ mW/m2).
