Description

The maturation contours show vitrinite reflectance trends and ranges for five key petroleum system horizons within the Uinta-Piceance Province. The horizons are the lower part of the Green River Formation, the base of the Mesaverde Group/top of Mancos Shale, the base of the Mancos Shale, the base of the Phosphoria Formation, and coal within the Ferron Sandstone Member of the Mancos Shale. The ranges of vitrinite reflectance shown for the horizons other than the Phosphoria Formation and the Ferron Sandstone are 1.35. The ranges for the Phosphoria Formation are 4.0; the ranges for the Ferron Sandstone Member are 1.25.
