Sandy fluvial deposit—Consisting of variegated mudstone, siltstone, and sandstone. 

Sandstone generally comprises more than 50 percent of interval.

Variegated mudstone, siltstone, and sandstone with anhydrite—Probably 

deposited in shallow, saline lakes or playa lakes.

Tmax is defined as the pyrolysis temperature at which the 

maximum amount of hydrocarbon is released by kerogen 

during Rock-Eval pyrolysis. H/C is the atomic hydrogen to 

carbon ratio measured in kerogen using an elemental analyzer. 

Depth of sample in feet is included.

Detailed South to North Cross Section Through the Uinta Basin, Utah

Lithologies shown at each drill hole are modified from American Stratigraphic 

Company (Amstrat) descriptions and available mudlogs (many are available at 

http://oilgas.ogm.utah.gov/). Lithologies shown for surface sections on the south end 

of the cross section are modified from Cashion (1967). Interpretations of depositional 

settings are new to this report. Oil yields in gallons per ton based on the Fischer 

assay method were available for seven of the drill holes. Analyses are available at 

Johnson and others (2010b, http://pubs.usgs.gov/dds/dds-069/dds-069-bb/). Other 

information included on the cross section are:

(1) results from drillstem tests and perforations (available at Utah oil and Gas 

website http://oilgas.ogm.utah.gov/),

(2) mudweights used during drilling (from well log headers),

(3) and vitrinite reflectance (Ro

) and Rock-Eval analysis from Anders and others 

(1992).
