A revised version of Graphic Normative Analysis Program (GNAP) with examples of petrologic problem solving
J. S. Stuckless, G. VanTrump
1979, Open-File Report 79-1237
A revised version of Graphic Normative Analysis Program (GNAP) has been developed to allow maximum flexibility in the evaluation of chemical data by the occasional computer user. GNAP calculates ClPW norms, Thornton and Tuttle's differentiation index, Barth's cations, Niggli values and values for variables defined by the user. Calculated values...
Water-quality reconnaissance of lakes in Voyageurs National Park, Minnesota
G. A. Payne
1979, Open-File Report 79-556
Water samples were collected from three lakes in Voyageurs National Park to assess chemical and biological water quality in March and August 1977. Bottom material samples were also collected and analyzed for chemical quality. Results of the analyses show that the water system was dilute; specific conductance ranged from 32...

The mean, variance, standard deviation, skewness, and coefficient of variation are...
Digital-transport model study of Diisopropylmethylphosphonate (DIMP) ground-water contamination at the Rocky Mountain Arsenal, Colorado
James W. Warner
1979, Open-File Report 79-676
Diisopropylmethylphosphonate (DIMP) is an organic compound produced as a byproduct of the manufacture and detoxification of GB nerve gas. Ground-water contamination by DIMP from the disposal of wastes into unlined surface ponds at the Rocky Mountain Arsenal occurred from 1952 to 1956. A digital-transport model was used to determine the...
