Subsidence of a volcanic basin by flexure and lower crustal flow: the eastern Snake River Plain, Idaho

A study was conducted on the northwest edge crustal flexure of the eastern Snake River Plain, ID. The basin's dense load dimensions were modeled using the flexure. Results indicate lower crustal flow from the basin and density-driven subsidence. Subsidence and isostatic equilibrium were found to be caused by density-driven lower crustal flow. Exploratory wells in the area were also found to constrain the timing of subsidence.
