<br />GEOLOGIC STRATICPu"PHY AND DESCRIPTIO!' OF ConTINENTAL HELL NO. 1 <br /> <br />Depth (ft) <br />0-100 <br /> <br />650-14,620 <br /> <br />Geologic Description <br /> <br />Alluvial Materials; unconsolifiated sand, <br />silt, and gravel deposited by the Dolores <br />River, Quaternary age. <br /> <br />Hermosa Formation; composed of three units <br />all of the Pennsylvanian Age. <br /> <br /> <br />Upper Hermosa and Honaker Trail member; <br /> <br /> <br />composed of interbedded limestones, <br /> <br /> <br />anhydrite shales, and siltstones. <br /> <br /> <br />Paradox member; saline facies composed <br />of thick salt beds interbedded "ith <br />shales, limestone, and gypsum. Struc- <br />tural deformation has greatly thickened <br />this unit in the Paradox area. <br /> <br />100-14,670 <br /> <br />100-650 <br /> <br />14,620-14,670 <br /> <br />Lower Hermosa or Pinkerton Trail member; <br />similar to Upper Hermosa member in <br />composition. <br /> <br />14,670-14,726 <br /> <br />Molas Formation; of Early Pennsylvanian age, <br /> <br /> <br />composed of varigated siltstone, shale, and <br /> <br /> <br />calcareous sandstone. <br /> <br />14,726-14,968 <br /> <br />Leadville (Redwall) Limestones; Mississippian <br /> <br /> <br />age, composed of limestone containing fractures <br /> <br /> <br />and voids with some Dolomite and Chert. This <br /> <br /> <br />is the proposed formation for brine injection. <br /> <br />There could be other formations below this <br />capable of additional disposal. <br /> <br />(From Well Log of Scorup, etal #1) <br /> <br />FIGLRE 8 <br /> <br />(JOC4i 9 <br />
