From the Introduction:

Beginning in 1975, the CGS, in cooperation with the U.S. Geological Survey, has had an on-going project to evaluate the chemical composition of Colorado coals. This project entailed sampling of active and inactive mines and cores from drilling projects throughout the state. The samples were treated in a methodical manner to ensure consistency of results. Proximate, ultimate, and heat-of-combustion analyses are included for all samples. In most cases, trace element analyses are included; in some cases, petrographic analyses. Where available, stratigraphic information is included to aid in estimating, evaluating, and classifying Colorado coals.

The 1975 data for 64 samples are presented in IS-07, including a total of 295 samples from 100 locations collected from 1976-1979, broken down as follows: 270 are coal samples, 25 are rock samples, 114 samples are from coal mines, and 181 are from drill cores.
