... the Pakoon Formation is the Quantoweap Sandstone deposited in a shallow-marine environment. Overlying the Quantoweap Sandstone is gypsum and gypsiferous siltstone of the Seligman Member of the Toroweap Formation, representing the second regression. During this regression a sabkha developed along what is now...

... Sandstone, through the overlying confining unit, the gypsiferous silty Seligman Member of the Kaibab Formation. Mass-balance modeling suggests that the majority of CO 2 discharge is the product of the quantitative dissolution of CO 2 gas at depth within the fault zone. Upon discharge, most of the carbon...
