| Abstract: | A procedure for calculating the quantities of normative minerals and kerogen in Colorado oil shale was developed and used to analyze a sequence of sodium-rich oil shales in a core hole near the depocenter of the Piceance Creek Basin in northwestern Colorado. The sequence of oil shales was found to average 48. 1 weight percent carbonate minerals, 32. 5 percent silicate minerals, 1. 9 percent pyrite, and 17. 5 percent kerogen. Dawsonite left bracket NaAl(OH)//2CO//3 right bracket and quartz are associated to a high degree in the vertical sequence, but no significant trends between mineral abundances and depth were noted. |
